The coast, also known as the coastline, shoreline or seashore, is defined as the area where land meets the ocean, or as a line that forms the boundary between the land and the coastline. Shores are influenced by the topography of the surrounding landscape, as well as by water induced erosion, such as waves. The geological composition of rock and soil dictates the type of shore which is created. The Earth has around 620,000 kilometres (390,000 mi) of coastline. Coasts are important zones in natural ecosystems, often home to a wide range of biodiversity. On land, they harbor important ecosystems such as freshwater or estuarine wetlands, which are important for bird populations and other terrestrial animals. In wave-protected areas they harbor saltmarshes, mangroves or seagrasses, all of which can provide nursery habitat for finfish, shellfish, and other aquatic species. Rocky shores are usually found along exposed coasts and provide habitat for a wide range of sessile animals and various kinds of seaweeds. In physical oceanography, a shore is the wider fringe that is geologically modified by the action of the body of water past and present, while the beach is at the edge of the shore, representing the intertidal zone where there is one. Along tropical coasts with clear, nutrient-poor water, coral reefs can often be found between depths of 1–50 meters.
Lebanon is a small country in the Eastern Mediterranean, located at approximately 34˚N, 35˚E. It stretches along the eastern shore of the Mediterranean Sea and its length is almost three times its width. From north to south, the width of its terrain becomes narrower. Lebanon's mountainous terrain, proximity to the sea, and strategic location at a crossroads of the world were decisive factors in shaping its history.
Industrial waste is the waste produced by industrial activity which includes any material that is rendered useless during a manufacturing process such as that of factories, mills, and mining operations. Types of industrial waste include dirt and gravel, masonry and concrete, scrap metal, oil, solvents, chemicals, scrap lumber, even vegetable matter from restaurants. Industrial waste may be solid, semi-solid or liquid in form. It may be hazardous waste or non-hazardous waste. Industrial waste may pollute the nearby soil or adjacent water bodies, and can contaminate groundwater, lakes, streams, rivers or coastal waters. Industrial waste is often mixed into municipal waste, making accurate assessments difficult. An estimate for the US goes as high as 7.6 billion tons of industrial waste produced annually, as of 2017. Most countries have enacted legislation to deal with the problem of industrial waste, but strictness and compliance regimes vary. Enforcement is always an issue.
Water pollution is the contamination of water bodies, with a negative impact on their uses. It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from one of four main sources. These are sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater. Water pollution may affect either surface water or groundwater. This form of pollution can lead to many problems. One is the degradation of aquatic ecosystems. Another is spreading water-borne diseases when people use polluted water for drinking or irrigation. Water pollution also reduces the ecosystem services such as drinking water provided by the water resource.
New Jersey Meadowlands, also known as the Hackensack Meadowlands after the primary river flowing through it, is a general name for a large ecosystem of wetlands in northeastern New Jersey in the United States, a few miles to the west of New York City. During the 20th century, much of the Meadowlands area was urbanized, and it became known for being the site of large landfills and decades of environmental abuse. A variety of projects began in the late 20th century to restore and conserve the remaining ecological resources in the Meadowlands.
Marine debris, also known as marine litter, is human-created solid material that has deliberately or accidentally been released in seas or the ocean. Floating oceanic debris tends to accumulate at the center of gyres and on coastlines, frequently washing aground, when it is known as beach litter or tidewrack. Deliberate disposal of wastes at sea is called ocean dumping. Naturally occurring debris, such as driftwood and drift seeds, are also present. With the increasing use of plastic, human influence has become an issue as many types of (petrochemical) plastics do not biodegrade quickly, as would natural or organic materials. The largest single type of plastic pollution (~10%) and majority of large plastic in the oceans is discarded and lost nets from the fishing industry. Waterborne plastic poses a serious threat to fish, seabirds, marine reptiles, and marine mammals, as well as to boats and coasts.
Marine pollution occurs when substances used or spread by humans, such as industrial, agricultural and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean and cause harmful effects there. The majority of this waste (80%) comes from land-based activity, although marine transportation significantly contributes as well. It is a combination of chemicals and trash, most of which comes from land sources and is washed or blown into the ocean. This pollution results in damage to the environment, to the health of all organisms, and to economic structures worldwide. Since most inputs come from land, either via the rivers, sewage or the atmosphere, it means that continental shelves are more vulnerable to pollution. Air pollution is also a contributing factor by carrying off iron, carbonic acid, nitrogen, silicon, sulfur, pesticides or dust particles into the ocean. The pollution often comes from nonpoint sources such as agricultural runoff, wind-blown debris, and dust. These nonpoint sources are largely due to runoff that enters the ocean through rivers, but wind-blown debris and dust can also play a role, as these pollutants can settle into waterways and oceans. Pathways of pollution include direct discharge, land runoff, ship pollution, bilge pollution, atmospheric pollution and, potentially, deep sea mining.
Environmental issues in Venezuela include oil spills, illegal mining, deforestation, tourism, water shortages, pollution, poor waste management and hazards such as earthquakes, floods, rockslides, mudslides, and periodic droughts.
Jieh is a seaside town in Lebanon with an estimated population of 5000, 23 km south of Beirut, in the Chouf district via a 20-minute drive along the Beirut to Sidon highway south of the capital. In Phoenician times it was known as Porphyreon and was a thriving natural seaport, which still functions today. The town is also known for its seven kilometre sandy beach, a rarity along Lebanon's mainly rocky coastline.
Marine Protection, Research and Sanctuaries Act of 1972 (MPRSA) or Ocean Dumping Act is one of several key environmental laws passed by the US Congress in 1972. The Act has two essential aims: to regulate intentional ocean disposal of materials, and to authorize any related research. While the MPRSA regulates the ocean dumping of waste and provides for a research program on ocean dumping, it also provides for the designation and regulation of marine sanctuaries. The act regulates the ocean dumping of all material beyond the territorial limit and prevents or strictly limits dumping material that "would adversely affect human health, welfare, or amenities, or the marine environment, ecological systems, or economic potentialities". The MPRSA authorized the Environmental Protection Agency (EPA) to regulate ocean dumping of materials including, but not limited to, industrial waste, sewage sludge, biological agents, radioactive agents, NBC, garbage, chemicals, and biological and laboratory, as well as other wastes, into the territorial waters of the United States through a permit program. The EPA can issue permits for dumping of materials other than dredge spoils if the agency determines, through a full public notice and process, that the discharge will not unreasonably degrade or endanger human health or welfare or the marine environment. The law also has provisions related to creating marine sanctuaries, conducting ocean disposal research and monitoring coastal water quality.
The Jiyeh Power Station oil spill is an environmental disaster caused by the release of heavy fuel oil into the eastern Mediterranean after storage tanks at the thermal power station in Jiyeh, Lebanon, 30 km (19 mi) south of Beirut, were bombed by the Israeli Air force on July 14 and July 15, 2006 during the 2006 Israel-Lebanon conflict. The plant's damaged tanks leaked up to 30,000 tonnes of oil into the eastern Mediterranean Sea, A 10 km wide oil slick covered 170 km of coastline, and threatened Turkey and Cyprus. The slick killed fish, threatened the habitat of endangered green sea turtles, and potentially increased the risk of cancer.
Like most former republics of the Soviet Union, Azerbaijan experienced rapid economic development which has led to an increasingly negative impact on the environment, including the inefficient usage of natural resources. The government of Azerbaijan has aimed to increase environmental protection and ensure rational utilization of natural resources, and has introduced a number of important laws, legal documents and state programs in order to improve the ecological situation in the country. However, these precautionary laws have not been as effective as they were meant to be. Transparency has been a consistent issue in Azerbaijan, as NGOs who are given legal authority to collect data from the oil refineries are often blocked or dismissed, and their information is gathered unofficially. Domestic oil producers have often evaded the regulations, and have not prevented oil leaks into the Caspian Sea. In the next 30 years, Azerbaijan will produce more oil than it produced during the 20th century, and currently there is little coordination or environmental precaution in the oil drilling operations. There is also a lack of communication with neighboring countries bordering the Caspian Sea.
In the United States, several federal agencies and laws have some jurisdiction over pollution from ships in U.S. waters. States and local government agencies also have responsibilities for ship-related pollution in some situations.
The environmental effects of shipping include air pollution, water pollution, acoustic, and oil pollution. Ships are responsible for more than 18% of nitrogen oxides pollution, and 3% of greenhouse gas emissions.
Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and industry, although laws and regulations introduced in the late 20th century have improved water quality in many water bodies. Extensive industrialization and rapid urban growth exacerbated water pollution as a lack of regulation allowed for discharges of sewage, toxic chemicals, nutrients and other pollutants into surface water.
Pollution is an environmental issue in Canada. It has posed health risks to the Canadian population and is an area of concern for Canadian lawmakers. Air, water and soil pollution as well as the associated health effects are prominent points of contention in modern Canadian society.

This is a list of notable events relating to the environment in 2006. They relate to environmental law, conservation, environmentalism and environmental issues.
Beach cleaning or clean-up is the process of removing solid litter, dense chemicals, and organic debris deposited on a beach or coastline by the tide, local visitors, or tourists. Humans pollute beaches with materials such as plastic bottles and bags, plastic straws, fishing gear, cigarette filters, six-pack rings, surgical masks and many other items that often lead to environmental degradation. Every year hundreds of thousands of volunteers comb beaches and coastlines around the world to clean this debris. These materials are also called “marine debris” or "marine pollution" and their quantity has been increasing due to anthropocentric activities.
