South Korea has the highest level of environmental pollution among OECD countries. With a population density of 492 people per square kilometer, it ranks third in the world, with more than half of the population living in the Seoul metropolitan area, which accounts for 11.8% of the land area. Therefore, since the population density of the metropolitan area is 4,169, the environmental pollution problem has a characteristic proportional to the population, so it is natural that the environmental pollution level is high. In addition, it is calculated that urban land will take 3,838 km (1,300 times the area of Yeouido) over the next 20 years, and 65 times the area of Yeouido will be developed as a residential or industrial complex every year. Accordingly, the forest area is decreasing by 78 km, and the tidal flat by 36 km every year, indicating how serious the environmental damage in Korea is. [1]
Moreover, the amount of waste that pollutes the environment is nine times that of the United States, four times that of fertilizer and pesticides, and eight times that of sulfur dioxide is emitted, so the seriousness of environmental pollution is bound to intensify day by day. As if to prove this, the average temperature of the Earth has risen by 0.74 degrees Celsius over the past 100 years, but Korea has risen by 1.5 degrees Celsius, twice as much as this. If Korea's warming trend continues as it is, greenhouse gases could double from the current level by 2030, raising the temperature on the Korean Peninsula to up to 4 degrees Celsius. Accordingly, it is expected that all crops and fruits will lead to a decrease in production by more than 30%. [1]
If the temperature of the Earth rises by 1 degree Celsius, the location conditions of the ecosystem change by 100 kilometers. However, if the temperature in Korea rises by 4 degrees Celsius in the next 20 years, the location conditions of the ecosystem will change by 400 kilometers. In other words, the ecosystem in Busan will lead to a big change in moving north to Seoul. Ecosystems are connected by food chains, so when the ecosystem is relocated, creatures that cannot move will eventually disappear from Earth. The Korean Peninsula is suffering from such climate change, and various environmental pollution issues are bothering us, so environmental issues should be the best challenge for Korea. [1]
The environment can be divided into a geographical environment and a social environment. Geographic environment refers to an objectively and physically given environment. It can be seen that the components of the geographical environment interact to form a unity. In other words, it generally refers to the natural appearance of the natural environment. On the other hand, the social environment refers to the inclusion of ideas, values, and human behavior. It is formed by humans and appears differently depending on the times and society. Pedagogy explains that although it is unclear which environment human behavior is more affected, changing the social environment is more important to human life than changing the natural environment. [1]
Further information: Environment of South Korea
South Korea occupies the southern portion of the Korean Peninsula, which extends some 1,100 km (680 mi) from the Asian mainland. This mountainous peninsula is flanked by the Yellow Sea to the west, and the Sea of Japan to the east. Its southern tip lies on the Korea Strait and the East China Sea. [2]
The country, including all its islands, lies between latitudes 33° and 39°N, and longitudes 124° and 130°E. Its total area is 100,032 square kilometers (38,622.57 square miles). [3]
South Korea can be divided into four general regions – an eastern region of high mountain ranges and narrow coastal plains: a western region of broad coastal plains, river basins, and rolling hills; a southwestern region of mountains and valleys; and a southeastern region dominated by the broad basin of the Nakdong River. [4] South Korea is home to three terrestrial ecoregions: Central Korean deciduous forests, Manchurian mixed forests, and Southern Korea evergreen forests. [5]
South Korea's terrain is mostly mountainous, most of which is not arable. Lowlands, located primarily in the west and southeast, make up only 30% of the total land area. [2]
About three thousand islands, mostly small and uninhabited, lie off the western and southern coasts of South Korea. Jeju is about 100 kilometers off the southern coast of South Korea. It is the country's largest island, with an area of 1,845 square kilometers (712 square miles). Jeju is also the site of South Korea's highest point: Hallasan, an extinct volcano, reaches 1,950 meters (6,400 feet) above sea level. The easternmost islands of South Korea include Ulleungdo and Liancourt Rocks, while Marado and Socotra Rock are the southernmost islands of South Korea. [4]
Korea is high in the east and low in the west. During the Cenozoic era, the crust spread widely on both sides in the middle of the East Sea, and at this time, the land of Korea rose up under the power transmitted horizontally transmitted. In this process, the east rose higher than the west, forming the current topography of Donggo West. The Nangrim Mountains and Taebaek Mountains, which stretch north and south along the east coast, were also created during this period. And the high, rugged mountains, hills, and valleys developed widely around the two mountains. [6]
If you go east along the Yeongdong Expressway, which runs from Incheon to Gangneung, and enter Gangwon Province, we can meet several tunnels. The reason why there are many tunnels is because of the topography of the east and west. There are many high and rough mountains in Gangwon-do in the east, so we had to make a tunnel through holes in the mountain to make a road. So tunnels are concentrated in the east, where there are many mountainous areas in Korea. [6]
The topography of Donggo West and West also affected the flow of rivers. Since water flows from high to low, most rivers in Korea start from the east and flow to the west. South Korea's Han River, Geumgang River, and Yeongsan River, as well as North Korea's Daedong River and Yalu River, flow west. It also affected the development of the plains. Because plains are developed in the downstream of the river, the plains are spread out in the downstream of the river in the west. [6]
In Korean rivers, the watershed is biased toward the east coast, so the rivers flowing into the East Sea are short and there are many rapid currents, but the rivers flowing west or southwest are gentle and long. Usually, rivers flow through the old valley and semi-plain to form an extremely gentle equilibrium river, and erosion basins, floodplains, and natural embankments are developed in the middle and downstream due to long-term erosion, and there are many places that form a river terrace in the upper stream. Due to the uneven distribution of precipitation according to the season, it is difficult to develop and use the river due to the large change in rainfall, especially due to the heavy rains in the summer, which accumulates in the lower part of the river, causing frequent flooding. [13]
There are a total of 24 Ramsar registered wetlands in South Korea. First, the Ramsar Convention is the first international agreement on conservation and wise use of natural resources and habitats, and it presents basic directions for conservation and wise use of wetland resources. [17]
The types are Daeamsan Yong Wetland, Upo Wetland, Jangdo Wetland, Suncheonman Bay and Boseong Mudflats, Jeju Mulyeongari Wetland, Duung Wetland, Mujechi Wetland, Muan Mudflat, Jeju Muljang Orio Wetland, Jeju 1100 Wetland, Seocheon Mudflat, Gochang Wetland, Dongbangdo Island, and Daebangdo Wetland. [18]
Suncheonman Bay, which is well-known as a representative coastal wetland in Korea, is formed on Daedo Island, Suncheon-si, Jeollanam-do. Suncheon Bay Wetland is a representative ecotourism destination in Korea, as it was designated as a must-see list in the 2011 Michelin Green Guide Korean edition. At low tide, the wide tidal flats around the estuary are exposed, making it a destination for various migratory birds, and the Dongcheon Estuary turns into a deep tidal valley. Rice paddies, salt fields, tidal villages, aquaculture fields, low hills, and mountains are adjacent to the surrounding land, forming a unique ecosystem, scenery, and culture. In particular, the area of Suncheonman Bay tidal flat is 22.21 km2, of which reed colonies account for 2.3 km2. [19]
The national parks of South Korea are as follows. It refers to a park designated and managed by the state for the purpose of protecting and fostering representative scenic spots of the state and contributing to the improvement of people's health, rest and emotional life. The national park is a designated natural landscape representing Korea's landscape, including natural scenery, historic historical sites, and protecting rare animals and plants. In Korea, after consulting with representatives of related ministries and offices to hear the opinions of the competent governor, it is designated by the Minister of Environment after deliberation by the National Land Construction Comprehensive Development Council. Therefore, the Minister of Environment decides on the park plan to promote the efficient protection and use of the park. [20]
In addition to Jirisan Mountain, there are Gyeongju, Gyeryongsan Mountain, Hallyeohaesang, Songnisan Mountain, Hallasan Mountain, Seoraksan Mountain, Naejangsan Mountain, Gayasan Mountain, Odaesan Mountain, Deokyusan Mountain, Juwangsan Mountain, Taean Coast, Dadohaean Mountain, Bukhansan Mountain, Woraksan Mountain, Wolchulsan Mountain, Byeonsan Peninsula, Mudeungsan Mountain, and Taebaeksan National Park. [21]
The representative national park of Korea is Juwangsan National Park. Developed at the end of the Taebaek Mountain Range, this place is famous for its strange rocks and bizarre stones surrounded like a bottle, and it is said that King Juwon, the prince of Silla, lived and practiced asceticism. The tourist resources here include Zahaseong Fortress at the foot of the mountain, as well as Giam, Zahaam, Juwanggul Cave, and Haksodae, and Dalgi Mineral Spring is also famous nearby. [22]

Floating is the activity of jogging and picking up trash, which protects health and the environment together. It first started in Sweden in 2016. The meaning of the term is also a flogging made by combining 'pick up' and 'jogging' in Swedish. In Korean, the term 'picking up' is also used. It is a job to pick up conspicuous garbage and clean it while jogging, and it can be seen as an environmental protection movement that takes care of health at the same time as exercise. [23]
Recently, along with ESG management, flogging campaigns have been carried out in various places such as local governments, public institutions, companies, and organizations. In addition, flogging websites, communities, and small groups were formed. Flogging campaigns are steadily and widely spreading through SNS. [24]
Examples of floating include Samyang Group's recent flogging activities, [25] a flogging mountaineering club with celebrities, [26] and Jeju Olle Trail flogging day. [27] Changing the perception of small citizens through flogging and leading actions are the solutions for environmental problems. Therefore, it is time to recognize and respond to this. [28]
Carbon neutrality is the concept of making the actual emission of carbon dioxide "zero" by taking measures to absorb carbon dioxide as much as it emits carbon dioxide. Carbon neutrality is also called carbon zero. The main purpose is to reduce or eliminate greenhouse gas emissions to prevent global warming. Since the late 2010s, ESG management has become a hot topic, and as domestic carbon emission rights and carbon borders between countries have emerged, each company declared RE100. Here, RE100 stands for Renewable Energy 100, and refers to an international enterprise-to-business agreement project to replace 100% of the electricity used by companies with renewable energy by 2050. To achieve this, it is necessary to use only power generated from renewable energy or to purchase a certificate of supply of renewable energy (REC) as much as the power used. [29]
The domestic policy situation of the Republic of Korea is as follows. In February 2020, the 'Low Carbon Social Vision Forum', which consists of 100 experts, submitted a report to the Ministry of Environment. Based on this, 15 government ministries were created. On October 28, 2020, President Moon Jae In announced the "2050 Carbon Neutrality Declaration" at the plenary session of the National Assembly. [30] On January 19, 2022, the Ministry of Environment presented four major goals this year: establishing a basic carbon-neutral green growth plan, implementing a carbon-neutral practice point system, creating a green converting economic ecosystem, and fostering 1,300 high-quality workers. [31]
Let's look at the current status of carbon neutrality in domestic companies. In 2021, Ssangyong C&E declared de-coal management to be the first in the industry to reduce the amount of bituminous coal used to '0'. It also announced that it will invest a total of 282 billion won by 2030 to make large-scale facility investments. [32] In addition, Hyundai Motor has released a video on carbon neutrality. [33] In his New Year's address in 2022, Chae Hee-bong, president of the Korea Gas Corporation, cited carbon neutrality as a project for carbon neutrality this year, especially related to the environment of "introduction of overseas green hydrogen, mixing natural gas pipes and hydrogen". [34]
Korea has a lot of social contradictions and careers as it is rapidly industrialized and is rushing to grow into an advanced country. Particularly serious is the environmental issue. A representative example that can explain Korea's environmental pollution is the Nakdong River phenol pollution incident by Doosan Electronics in 1991. Due to this incident, water sources in Daegu and Busan were contaminated, so tap water could not be consumed for several days. Because I knew that the water was very polluted. [35]
The garbage problem is also being treated as a major challenge for the city. In the meantime, nearly 400 "waste mountains" with illegal waste have been created throughout the country. Local governments sometimes have serious disputes in Seoul, Incheon, and Gyeonggi Province because they cannot find a place to throw away garbage. This is worth calling a 'waste mess'. The problem of automobile exhaust is also an urgent problem that cannot be neglected. [36]
Recently, according to an analysis of the "2019 World Air Quality Report" published by Air Visual, a global air pollution research institute, Korea ranked first among OECD members and was the worst air pollution country. Since such air pollution has been affected by weather conditions, the number of days of high-concentration fine dust in Korea is continuously increasing. Therefore, it is time to respond strongly to the climate crisis to reduce atmospheric congestion caused by climate change, and a ban on fossil fuel reduction and use is suggested as a fundamental solution. Greenhouse gas reduction should also be considered at the same time as reducing air pollutants. [37]
Korea faces a big climate crisis. According to several international official reports, South Korea is expected to experience more frequent storms and problems as sea levels rise, even if various measures are taken. And if the sea level rises by 2 to 3 meters, cities that seemed irrelevant will be greatly affected. [38]
The climate crisis also affects domestic agriculture. Among the changes caused by the climate crisis, water shortage is the factor that will affect domestic agriculture the most. Although precipitation increases due to the climate crisis, drought persists for crops as rainfall patterns change differently than they do now. In addition, the amount of water that rains naturally supply to arable land is expected to decrease significantly, so the damage from the climate crisis is expected to become more and more serious. [39]
The climate crisis response is also our 'self-help'. Heat waves, wildfires, droughts, and floods all over the world are no one else's business. Large-scale disasters can occur at any time in Korea, and forest fires in Gangneung in 2017, heat waves in 2018, Goseong in 2019, and Sokcho have already occurred amid the climate crisis trend. Natural disasters will become more frequent and stronger if climate policies are not prepared to respond to the climate crisis. [40]

Global warming is a problem that is applied to Korea as well as the world. Global warming means that the global average surface temperature rises over a long period of time in a broad sense. Compared to 1850, the average global surface temperature has risen by more than 1 degree and is steadily increasing. [52]
Global warming started with the start of industrialization. At the beginning of the Industrial Revolution, the concentration of carbon dioxide in the atmosphere was 280 ppm. However, it increased exponentially after the Industrial Revolution, reaching about 405 ppm in December 2017. If there are no regulations on carbon dioxide emissions in the future, it is estimated to exceed about 450 ppm by 2050. Modern global warming is evaluated to be due to the increase in greenhouse gases containing carbon dioxide due to human activities. [53]
The situation of global warming in Korea is as follows. Korea's climate is an appropriate mix of cold and temperate zones, where four seasons are clearly visible. However, in the summer of 2007, we discovered that our country's climate was entering a subtropical climate more than ever before. Recently, the summer weather in Korea has weakened the rainy season in July, but the phenomenon of localized torrential rains in August is becoming remarkable. In the past, precipitation in Korea was concentrated during the rainy season from late June to late July, but recently, precipitation was concentrated in late July and August, resulting in a reversal. In other words, this change in climate shows that the average surface temperature in Korea has increased. [54]
In addition, abnormal climate phenomena have been frequently seen in Korea recently. Even though the weather is clear, dark clouds suddenly come and pour out rain, and the sun rises again as if it were ever. In addition, drought occurred in spring, the rainy season was prolonged, and flooding occurred. This climate change is expected to threaten various ecosystems and have a great impact on our lives. [55]
Air pollution in Korea is increasingly a threat to people and the environment. Air pollution starts with many causes, both at home and international. Since rapid industrialization, many forms of pollution have increased, especially in Seoul and other cities. Seoul is one of the most polluted cities, according to the National Aeronautics and Space Administration (NASA) Since 2009 and 2013, the city's average PM10 has been higher than many large cities around the world, such as Los Angeles, Tokyo, Paris, and London. In addition, it is estimated that about 16% of the deaths in 2010 in the Seoul metropolitan area were air quality. This has led to health and environmental problems. Koreans are buying masks and air purifiers to breathe cleaner air, and trying to reduce Korea's air pollution emissions. [56]
Pollution in Korea has increased since World War II. In 1960, Korea was still a developing country with few manufacturing industries and was heavily dependent on foreign aid. South Korean society began a major transition from an agricultural economy to an industrial economy, which was accelerated only by the Korean War. In the aftermath of the war, the United States provided significant aid to South Korea through the sponsorship of the United Nations Reconstruction Organization of Korea. The Korean economy, once a newly industrialized nation, grew by 10% annually until the 1980s and 1990s. Today, Korea is a manufacturing and export powerhouse, the world's 11th-largest gross domestic producer as of 2015, but this has been driven by coal-fired power generation and high vehicle emissions. The rapid growth has contributed to Korea's major air pollution, including diesel vehicles, construction equipment, heating and cooling, and power plants. [57]
The number of deaths from fossil fuel fine dust (2012) was the second highest in India (2.5 million) after China (3.9 million), but Bangladesh (36.5%) was the second highest after China (40.2%). Korea's fossil fuel fine dust mortality rate was the fourth highest at 30.5%. Looking at the death rate grid distribution, it was found that 4,000 to 5,000 people die annually in the metropolitan area. The average annual concentration of ultra fine dust was the highest in China with 62.9 μg/m3, followed by Bangladesh (52.3%), India (42.9%), and Korea (38.8%). The concentration of ultra fine dust in North Korea was also high at 30.5 μg/m3, resulting in a 26.2% death rate of fine dust in fossil fuels. [58]
The topography of the Korean Peninsula has the characteristics of east, west, and west. In other words, there are high mountain ranges in the east and most of the large rivers in the west, forming a granary where rice paddy farming can develop greatly. In the 1970s, the Park Chung-hee administration promoted a reclamation project to achieve national revival. In other words, in 1961, the Public Water Reclamation Act was enacted, and a reclamation project to secure farmland and agricultural water by blocking the estuary of the river and tidal flats flowing into the West Sea was carried out extensively. Moreover, two-thirds of the precipitation in Korea falls at once during the summer rainy season and goes down to the sea. Therefore, if an artificial lake that can store water flowing in the stream is not created, it will inevitably suffer from a serious lack of water. Therefore, there are 3,960 small and medium-sized rivers in Korea, with 18,800 appeals. However, there are only five natural appeals, and the rest are formed by artificial structures such as dams, estuaries, and reservoirs. [62]
Korea's total annual water resources are 127.6 billion tons, of which 45 percent, or 54.5 billion tons, are lost due to evaporation and penetration, and 39 percent, or 49.3 billion tons, are lost to the sea in the event of flooding. However, only 23.8 billion tons, or 18%, are usually leaked, so the total usage is far below 33.1 billion tons. Therefore, water use is 16.1 billion tons of river water, 13.3 billion tons of dam use, and 3.7 billion tons of groundwater use, which is a financial burden to solve the water shortage problem. By use, it is divided into 15.8 billion tons of agricultural water (48%), 7.3 billion tons of living water (22%), 2.9 billion tons of industrial water (9%), and 7.1 billion tons of maintenance water (21%). [62]
Meanwhile, 18,800 appeals in Korea are actually turning into hotbeds of water pollution. On top of that, a huge reservoir has been installed to promote the development of the four major rivers, and all parts of the country are suffering from serious water pollution. [62]
It is also called the "Samsung 1: Hebei Spirit Oil Spill Accident." A total of 12,547 km (78,918 barrels) of crude oil from the tanker tank leaked to waters near Taean when the Hong Kong-registered tanker Hebei Spirit collided with Samsung Heavy Industries' Samsung No. 1 off Taean, Chungcheongnamdo on December 7, 2007. It is generally called the Taean oil spill accident. [63]
Many fish and shellfish from nearby fish farms died as the oil spill caused turbidity in seawater and reduced dissolved oxygen. In addition, as fishing grounds become dilapidated, it affects the livelihood of the region and affects the local economy. It usually takes about 10 years at the earliest to normalize the local economy, and it will take 20 to 30 years at the longest (in the case of the Sea Prince oil spill off Yeocheon, Jeollanamdo, it was confirmed that oil slicks were found at the bottom of the sunken sea in 2005, 10 years after the incident). It is also expected that it will take up to 100 years for the marine ecosystem to return to its original state. [63]

The biodiversity crisis caused by the climate crisis is becoming a reality. The protection of vulnerable species in the climate crisis should be considered the top priority of the government's biodiversity maintenance policy. In addition, climate crisis measures are urgently needed for the management of endangered species. [69]
Recently, the weather has become serious, with summer in Korea becoming the hottest ever and winter becoming unprecedentedly warm. In the past, this phenomenon was described in terms of "climate change", but the extent of it got worse, and now it's called a "climate disaster". In particular, the climate disaster has threatened to mass extinction of barely surviving animals and plants. Although they live on the Korean Peninsula, there are representative animals in Korea that are sensitive to climate change, whose habitats are threatened by climate change without our perception. [71]
Korea's biodiversity is also faltering amid a global climate disaster. If animals in Korea disappear without adapting to the rapidly changing climate, changes in the ecosystem connected to them threaten the survival of other creatures. Therefore, we need the active interest and support of the Korean people to respond to the climate crisis now so that the ecosystem can be maintained healthy from the climate disaster and mankind can live safely in it. [78]
A social enterprise is a company that establishes and operates a business model that can realize social value and generate profits at the same time. There are various social enterprises operating in relation to the dual environment. The waste discharged is reborn and branded. Examples include LAR, high cycle, and beautiful shops. [79]
ESG stands for Environment, Social, and Government. In other words, it means the environment, society, and governance, which are non-financial elements of a company. These days, interest in ESG management is increasing as the social responsibility factor increases, not just the traditional method of emphasizing corporate performance or profits. Looking at the company's ESG management, it has emerged that the company's behavioral style can benefit society and have a positive impact. [83]
ESG management has already been introduced as a disclosure obligation system by Germany, Canada, Belgium, France, and Sweden, led by the UK in 2000. And South Korea introduced it in January 2021, and announced that it plans to expand all KOSPI-listed companies by 2030. It is not an option, but ESG management, which is now an obligation. [84]
As a recent example, ESG management has been accelerated by the practice of environmental protection in the life of Kyobo Life Insurance. Kyobo Life Insurance held a donation ceremony for Vietnam's Hope Tree and an environmental flogging campaign for executives and employees. [85]
There's also Coway's strides. Coway conducted the 2022 Coway River Flogging Campaign to clean up the environment in August this year, and also conducted the in-container challenge (a project to encourage executives and employees to use multiple containers instead of disposable products to participate in environmental protection), and the Clean School Classroom Project. [86]
The term "non-profit organization" means an organization that does not distribute profits from the operation of the organization to those who have paid for the establishment of the This includes small private businesses, consumer organizations, and charity and relief organizations. A non-profit organization uses all of its profits only for its operations. Non-profit organizations related to the environment include the Seoul Korea Federation for Environmental Movements, Noeul Park, Environmental Justice, and Happy Bean. [87]
The Seoul Korea Federation for Environmental Movements deeply recognizes that the sky, land, water, and ecosystems are being seriously destroyed by people's reckless behavior, and aims to turn the world into a safe and peaceful place for us and our descendants through our lives and environmental movements. [88]
Noeul Park is a group created to restore the ecological life of the old Nanjido land and give peace and cultural values to children growing up with clear nature instead of trash and the wisdom and peace of life instead of pain. [89]
Environmental Justice Environmental Justice is an environmental civic group that gathers people who try to solve environmental inequality in our society. In addition, there are Happy Bean and the Green Union. [90]
Vegan refers to an active vegetarian who does not eat any animal food (meat, milk, eggs, etc.). Recently, social interest in vegan has been increasing. For example, in Korea, an eco-friendly vegan brand recently entered Daiso. [91] In addition, there are cases of treating mourners with vegan food in funeral culture, [91] and the case of Korea's first upcycling vegan bread launch, "The Bread Blue," a vegan bakery brand that announced that it will launch the first vegan bread using upcycling ingredients with food upcycling company "Rihabest." [92]
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently for years or decades or seasonally for a shorter periods. Flooding results in oxygen-poor (anoxic) processes taking place, especially in the soils. Wetlands are different from other land forms or water bodies due to their aquatic plants adapted to oxygen-poor waterlogged soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods exist for assessing wetland functions and wetland ecological health. These methods have contributed to wetland conservation by raising public awareness of the functions that wetlands can provide. Constructed wetlands are a type of wetland that can treat wastewater and stormwater runoff. They may also play a role in water-sensitive urban design. Environmental degradation threatens wetlands more than any other ecosystem on Earth, according to the Millennium Ecosystem Assessment from 2005.
The environment of China comprises diverse biotas, climates, and geologies. Rapid industrialization, population growth, and lax environmental oversight have caused many environmental issues and large-scale pollution.
The natural environment or natural world encompasses all living and non-living things occurring naturally, meaning in this case not artificial. The term is most often applied to Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity. The concept of the natural environment can be distinguished as components:
Environmental issues in Nepal include a number of issues, such as deforestation, climate change, energy and species conservation. Many of these issues have been precipitated by rapid industrialization without major environmental regulation.
Marine ecosystems are the largest of Earth's aquatic ecosystems and exist in waters that have a high salt content. These systems contrast with freshwater ecosystems, which have a lower salt content. Marine waters cover more than 70% of the surface of the Earth and account for more than 97% of Earth's water supply and 90% of habitable space on Earth. Seawater has an average salinity of 35 parts per thousand of water. Actual salinity varies among different marine ecosystems. Marine ecosystems can be divided into many zones depending upon water depth and shoreline features. The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live. The benthic zone consists of substrates below water where many invertebrates live. The intertidal zone is the area between high and low tides. Other near-shore (neritic) zones can include mudflats, seagrass meadows, mangroves, rocky intertidal systems, salt marshes, coral reefs, lagoons. In the deep water, hydrothermal vents may occur where chemosynthetic sulfur bacteria form the base of the food web.
The Korea Federation for Environmental Movements (KFEM) is a non-profit organization in South Korea that focuses on environmentalism.
The environment of the United States comprises diverse biotas, climates, and geologies. This diversity leads to a number of different distinct regions and geographies in which human communities live. This includes a rich variety of species of animals, fungi, plants and other organisms.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity. Physical water scarcity is where there is not enough water to meet all demands. This includes water needed for ecosystems to function. Regions with a desert climate often face physical water scarcity. Central Asia, West Asia, and North Africa are examples of arid areas. Economic water scarcity results from a lack of investment in infrastructure or technology to draw water from rivers, aquifers, or other water sources. It also results from weak human capacity to meet water demand. Many people in Sub-Saharan Africa are living with economic water scarcity.
Freshwater biology is the scientific biological study of freshwater ecosystems and is a branch of limnology. This field seeks to understand the relationships between living organisms in their physical environment. These physical environments may include rivers, lakes, streams, ponds, lakes, reservoirs, or wetlands. Knowledge from this discipline is also widely used in industrial processes to make use of biological processes involved with sewage treatment and water purification. Water presence and flow is an essential aspect to species distribution and influences when and where species interact in freshwater environments.
Wetland conservation is aimed at protecting and preserving areas of land including marshes, swamps, bogs, and fens that are covered by water seasonally or permanently due to a variety of threats from both natural and anthropogenic hazards. Some examples of these hazards include habitat loss, pollution, and invasive species. Wetland vary widely in their salinity levels, climate zones, and surrounding geography and play a crucial role in maintaining biodiversity, ecosystem services, and support human communities. Wetlands cover at least six percent of the Earth and have become a focal issue for conservation due to the ecosystem services they provide. More than three billion people, around half the world's population, obtain their basic water needs from inland freshwater wetlands. They provide essential habitats for fish and various wildlife species, playing a vital role in purifying polluted waters and mitigating the damaging effects of floods and storms. Furthermore, they offer a diverse range of recreational activities, including fishing, hunting, photography, and wildlife observation.
The natural environment, commonly referred to simply as the environment, includes all living and non-living things occurring naturally on Earth.
The effects of climate change in Saskatchewan are now being observed in parts of the province. There is evidence of reduction of biomass in Saskatchewan's boreal forests that is linked by researchers to drought-related water stress stemming from global warming, most likely caused by greenhouse gas emissions. While studies, as early as 1988 have shown that climate change will affect agriculture, whether the effects can be mitigated through adaptations of cultivars, or crops, is less clear. Resiliency of ecosystems may decline with large changes in temperature. The provincial government has responded to the threat of climate change by introducing a plan to reduce carbon emissions, "The Saskatchewan Energy and Climate Change Plan", in June 2007.
Climate change has led to extreme weather events in South Korea that affects: social, economy, industry, culture, and many other sectors. South Korea is experiencing changes in climate parameters. Such parameters include annual temperature, rainfall amounts, and precipitation.
The environment of North Korea comprises the diverse ecosystems of the part of the Korean peninsula controlled by the Democratic People's Republic of Korea. This includes alpine, forest, farmland, freshwater, and marine ecosystems.
The wildlife of South Korea includes 8,271 plant species, 18,117 animal species and 3,528 species of fungi and others. 30,000 species are known to exist in South Korea, but it is estimated that there are more than 100,000 species.
The State of Israel is one of the smallest countries in the world, around 20,000 sq. km, and has relatively few natural resources. Due to its limited space, semi-arid climate, high population growth and resource scarcity, Israel is highly susceptible to environmental crises. These include water shortages and pollution, shrinking of the Dead Sea, waste production and disposal, air pollution and population density. As a result, resource development, in particular water, has benefited from relatively high government support throughout most of the country's history. For example, Israel's water conservation and reclamation infrastructure is one of the most advanced in the world, with approximately half its water supply derived from reclaimed and treated waste water, brackish water and desalinated water.
Israel, like many other countries in the Middle East and North Africa, experiences adverse effects from climate change. Annual and mean temperatures are increasing in Israel, with mean temperature expected to increase between 1.6 and 1.8 °C by 2100. There is a reduction in annual precipitation and delayed winter rains. Israel is already experiencing droughts and water shortages. Heatwaves are other natural hazards expected to increase with climate change.
