Antigua and Barbuda is a sovereign island country in the Caribbean. It lies at the conjuncture of the Caribbean Sea and the Atlantic Ocean in the Leeward Islands part of the Lesser Antilles.
Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, with half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. Estimates vary widely as to the extent of deforestation in the tropics. In 2019, nearly a third of the overall tree cover loss, or 3.8 million hectares, occurred within humid tropical primary forests. These are areas of mature rainforest that are especially important for biodiversity and carbon storage.
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. The environmental degradation process amplifies the impact of environmental issues which leave lasting impacts on the environment.
Habitat destruction occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved to elsewhere or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide.
Environmental issues in Mali include desertification, deforestation, soil erosion, drought, and inadequate supplies of potable water. Deforestation is an especially serious and growing problem. According to the Ministry of the Environment, Mali’s population consumes 6 million tons of wood per year for timber and fuel. To meet this demand, 4,000 square kilometers of tree cover are lost annually, virtually ensuring destruction of the country’s savanna woodlands.
Environmental issues in Haiti include a historical deforestation problem, overpopulation, a lack of sanitation, natural disasters, and food insecurity. The major reasons for these environmental issues are corruption, human exploitation, and the embezzlement of taxpayers' funds for personal gains. In addition, there is not sufficient protection or management of the country's natural resources. Other environmental issues, such as decreases in precipitation and more severe natural disasters, will likely arise in Haiti as a result of climate change. Experts agree that Haiti needs to adopt new policies to address both the issues that already exist and to prepare for the effects of climate change.
Environmental issues in Indonesia are associated with the country's high population density and rapid industrialisation, and they are often given a lower priority due to high poverty levels, and an under-resourced governance.
African environmental issues are caused by human impacts on the natural environment and affect humans and nearly all forms of life. Issues include deforestation, soil degradation, air pollution, water pollution, garbage pollution, climate change and water scarcity. These issues result in environmental conflict and are connected to broader social struggles for democracy and sovereignty.
Deforestation in Nigeria refers to the extensive and rapid clearing of forests within the borders of Nigeria. This environmental issue has significant impacts on both local and global scales.
According to a 2005 report conducted by the Food and Agriculture Organization of the United Nations (FAO), Vietnam has the second highest rate of deforestation of primary forests in the world, second only to Nigeria. The use of defoliants during the Vietnam War had a devastating and long-lasting impact on the country's forests and ecology, affecting 14-44% of total forest cover, with coastal mangrove forests being most affected.
The environment of Côte d'Ivoire has more than 1,200 animal species—223 mammal, 702 bird, 125 reptile, 38 amphibian, and 111 fish species—and 4,700 plant species. It is the most biodiverse country in West Africa, but unlike other countries there, its diversity isn't concentrated along the coast, but rather in the rugged interior. However, much like the rest of West Africa, Côte d'Ivoire has suffered severe deforestation.
Malaysia faces several environmental issues. Malaysia's environment possesses megadiverse biological diversity, with globally significant endemism and biodiversity, but is threatened by several issues. Deforestation is a major issue in the country that has led to many species becoming threatened with extinction. As a major economic sector, palm oil production has had a substantial environmental impact. Air pollution is also a major issue, with the country one of the most affected countries by seasonal Southeast Asian haze. The country is also affected by climate change.
Rates and causes of deforestation vary from region to region around the world. In 2009, two-thirds of the world's forests were located in just 10 countries: Russia, Brazil, Canada, the United States, China, Australia, the Democratic Republic of the Congo, Indonesia, India, and Peru.
Antigua and Barbuda lie in the eastern arc of the Leeward Islands of the Lesser Antilles, separating the Atlantic Ocean from the Caribbean Sea. Antigua is 650 km (400 mi) southeast of Puerto Rico; Barbuda lies 48 km (30 mi) due north of Antigua, and the uninhabited island of Redonda is 56 km (35 mi) southwest of Antigua.
The principal environmental issues in Peru are water pollution, soil erosion, pollution and deforestation. Although these issues are problematic and equally destructive, the Peruvian Environmental ministry has been developing regulation and laws to decrease the amount of pollution created in major cities and have been making policies in order to decrease the present deforestation rate in Peru.
Cuba possesses a diverse range of natural habitats, housing a wide variety of species, including many endangered ones. However, the country has faced environmental challenges, particularly deforestation, since the arrival of European settlers. Forest areas have been cleared for agricultural purposes, leading to the loss of forests and the extinction of certain species. The cutting down of trees for fuel and construction materials has further contributed to this issue.
Forest restoration is defined as “actions to re-instate ecological processes, which accelerate recovery of forest structure, ecological functioning and biodiversity levels towards those typical of climax forest” i.e. the end-stage of natural forest succession. Climax forests are relatively stable ecosystems that have developed the maximum biomass, structural complexity and species diversity that are possible within the limits imposed by climate and soil and without continued disturbance from humans. Climax forest is therefore the target ecosystem, which defines the ultimate aim of forest restoration. Since climate is a major factor that determines climax forest composition, global climate change may result in changing restoration aims. Additionally, the potential impacts of climate change on restoration goals must be taken into account, as changes in temperature and precipitation patterns may alter the composition and distribution of climax forests.
Environmental issues in Liberia include the deforestation of tropical rainforest, the hunting of endangered species for bushmeat, the pollution of rivers and coastal waters from industrial run-off and raw sewage, and the burning and dumping of household waste.
Climate changein the Caribbean poses major risks to the islands in the Caribbean. The main environmental changes expected to affect the Caribbean are a rise in sea level, stronger hurricanes, longer dry seasons and shorter wet seasons. As a result, climate change is expected to lead to changes in the economy, environment and population of the Caribbean. Temperature rise of 2 °C above preindustrial levels can increase the likelihood of extreme hurricane rainfall by four to five times in the Bahamas and three times in Cuba and Dominican Republic. Rise in sea level could impact coastal communities of the Caribbean if they are less than 3 metres (10 ft) above the sea. In Latin America and the Caribbean, it is expected that 29–32 million people may be affected by the sea level rise because they live below this threshold. The Bahamas is expected to be the most affected because at least 80% of the total land is below 10 meters elevation.
Senegal's environmental issues are varied. According to the CIA world factbook pressing problems exist with: diminishing wildlife populations which are threatened by poaching, deforestation, overgrazing, soil erosion, desertification, and overfishing.
