Does this Introduction sound fine for an Argument essay?

Forests probide many supplies that are essential in our lives. They give us oxygen, wood fiber for paper, herbs for medicine, and timber for building structures. Forest materials are so necessary that humans can't live for long without them. If we need trees to survive, why are so many forests being cut down? The question must be asked:
should deforestation go on? Deforestation should no longer go on, because endangered species are close to extinction, less oxygen is being produced and global warming is becoming a bigger issue because of it.

I don't know. I'd have to see the rest of the FINISHED essay to be able to tell.
