Deforestation is the cutting down of trees in forests. This causes many
problems. One of the main issues is that trees absorb the carbon dioxide
released by humans to use for photosynthesis; therefore if more trees are
being chopped down then less carbon dioxide is being chopped down.
Also the trees may be burned for fuel, which will release more carbon dioxide,
or the land cleared through deforestation may be used for agriculture, such
as breeding cattle who release methane which is also a greenhouse gas.
Another issue is that once the trees are chopped down, many animals will
lose there habitats and plants will be removed and therefore this process
reduces biodiversity within the environment.
