Environmental problem by refugee?

I heard that environmental problem by a refugee is serious today. For instance, cutting tree rapidly become serious.

If you know about the environmental problem by a refugee in detail, please tell me. And if you know the website when I understand more about the problem, please show me. Since I am an international student and need to write essay about this problem, I hope someone help me.Environmental problem by refugee?I consider refugees limited in their ability to do environmental damage. They just do not have the wealth or power. A refugee *might* cut a tree, but then 100 other refugees might not have one to cut. Someone wealthy might purchase an entire forest, and cut it down to make a sub-division.
