Another reason why we should maintain rainforests is flora. Rainforests provide 1/3 of our planets plant species. Some are very rare and can only be found in rainforests. Trees provide us with oxygen and if we don't stop cutting them down we wont have oxygen to breathe. If rainforests are not maintained the plant species will begin to die and be extinct. We should stop deforestation. To some big companies rainforests are only seen a lots of lumber to build buildings. If some types of plant species die, in turn will some animals too. An example is with orangutans and palm trees. Those trees are seen only a oil to food producers but the orangutans need them to survive. Can you imagine a world without beautiful flowers to smell and trees to provide us oxygen?
