Why is biodiversity important to rainforest's?

To maintain the eclogical balance between the orginisms in the rainforest.

It is the biodiversity on Earth that allows (at the moment) for animals, plants and humans to share the planet- if one species is destroyed, several, maybe even hundreds more, may follow Biodiversity is important because certain organisms have economic value (such as rainforest plants being made into medicine), they have value to the ecosystem (think of their spot on a food web), and they are a source of natural beauty and recreation. The answer above mine only states part of the answer (my second reason) as he refers to their value in the ecosystem (this is the official answer from a Prentice Hall SCIENCE EXPLORER Enviromental Science textbook) and without it there would no life on earth.

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.
