What do you mean? Do you think that measurable increase of global temperature is a rhetoric and not a fact?
I'm fairly certain the biggest threat that human industry poses is the chemical and polymer poisoning of the environment.

Sources would be helpful.
Most likely they wouldn't. You can find sources to back up almost any claim. Without the context they're not actually all that useful.
