Well, despite what many people may think, there are strong reasons to 
support the banning of deforestation. OK, first of all, rainforest land is not 
sustainable as farming land. The reason for this is that the land is only 
good for three to four crops before the soil becomes useless for growing 
food. Additionally, there is just too much rain in a rainforest to adequately 
support healthy food crops. A rainforest has a minimum annual rainfall of 
80 inches. The rain carries away the essential nutrients from the soil, 
especially after the protective canopy—or cover—of the trees is 
removed. If deforestation continues, farmers will need to continually 
move or cut down more trees to clear more and more fresh land to keep 
making money from their crops.

Also, keep in mind that creating more living space for densely populated 
areas displaces the local tribes and indigenous people who have lived 
there for years. Many of those indigenous people have never been 
outside their rainforest and have had no contact with other people. 
Bringing new people in would not only destroy their way of life, but would 
also make the rainforest unsustainable. That is, the local tribes are able 
to farm, hunt, eat, and find fuel without disrupting the rainforest 
environment. Additionally, bringing new people to the area exposes the 
local people to diseases and infections they’re not normally exposed to, 
potentially leading to deaths among the population.
Lastly, deforestation is devastating to the environment. There are direct 
links to the climate change it causes and to the loss of biodiversity. 
Deforestation is destroying the habitat for hundreds of species—plants, 
animals, and insects. Plants that are used for medicinal purposes are 
lost; for example, more than 25 percent of the ingredients needed for 
cancer drugs are found in the rainforest. The continued destruction may 
prevent future cures and medicines from ever being discovered. And, in 
general, the rainforests are believed to lessen global warming by 
decreasing carbon dioxide. They remove billions of tons of carbon 
dioxide from the air.
