A study highlighted in a 2022 Nature article underscores the broader climate benefits of tropical forests beyond carbon storage. Tropical forests cool the planet by one-third of a degree through biophysical mechanisms such as humidifying the air and releasing cooling chemicals, in addition to their role in extracting carbon dioxide from the air.
The typical tropical forest may become a carbon source by the 2060s. [46] Researchers have found that, in terms of environmental services, it is better to avoid deforestation than to allow for deforestation to subsequently reforest, as the latter leads to irreversible effects in terms of biodiversity loss and soil degradation.

A Liberian tropical forest. 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.
Deforestation in Central America is one of the environmental problems that is linked to the settlement of agrarian frontier areas by land-seeking farmers and commercial agrarians, who facilitated the conversion of forest land to pasture, more expansion of cash crop like coffee, banana, logging activities, pasture and fuelwoods among other urbanization activities.

Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
The effects of climate change on the water cycle have important negative effects on the availability of freshwater resources, as well as other water reservoirs such as oceans, ice sheets, the atmosphere and soil moisture. The water cycle is essential to life on Earth and plays a large role in the global climate system and ocean circulation.
Deforestation in the Maranhão state, Brazil, in July 2016. The Amazon rainforest, spanning an area of 3,000,000 km 2 (1,200,000 sq mi), is the world's largest rainforest.It encompasses the largest and most biodiverse tropical rainforest on the planet, representing over half of all rainforests.
Costa Rica's tropical landscape. Deforestation is a major threat to biodiversity and ecosystems in Costa Rica.The country has a rich biodiversity with some 12,000 species of plants, 1,239 species of butterflies, 838 species of birds, 440 species of reptiles and amphibians, and 232 species of mammals, which have been under threat from the effects of deforestation.
