What is the main reason that species are being lost to extinction?

Its either their environment has changed and they can't cope to survive anymore...or they are being eaten...:).

Well it's because the enviroment they live in is changing from cold to warm so being where they must live in cold isnt working out so well and other animals is couls likely be the same reason or they could be getting shot and keeping them either to eat or keeping it as an award to them. It could also have to deal with the food chaing eating one another...

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.
