The rain forest is a region rich in biodiversity. Richer than any other biological region of our planet. However, it is not the largest biological region, nor is it protected in many areas in which it grows.
Thus there are innumerable candidates which would fit your question. Many of these species are unknown to science, and may vanish before being documented In South America Jaguar, some sloths, some cayman, many monkeys, birds, and innumerable insects (which sadly merit little of our concern) are endangered In the rainforest's of Western Africa, Forest Elephant, Western and Eastern Gorilla, Brnaby, chimpanzee, Okapi, (once again) many insects, and many others are endangered In the rain forests of Northern Australia, Cassowary, tree Kangaroo, birds of paradise, and some Adina are endangered In Asia, Lions, Tigers, Asian Elephant, Orangutan, Clouded and Brennan Clouded Leopards, Rhino (of two species), and many other species are all endangered Many of these species are Critically Endangered, and all require our aid to survive About a specie disappears everyday in a rainforest when they are not even discovered yet! In any rainforest each tree may have it's species of wildlife that exist only on that tree.
Any tree cut down or fallen may result in the extinction of those species.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
