Of course humans have an effect. Six BILLION of anything is going to have an effect. It takes a lot of resources (food, energy, etc.) to raise human beings.

We certainly can be MUCH better about our use of resources and impact on our planet - but I don't agree that it should be forced. Encouraged, sure. Used as a locus of new innovation, sure.

I'm not going to get any more political than that, but I do think anyone who thinks that the activities of BILLIONS of human beings don't have an adverse impact on our planet is in denial, or perhaps huffing glue.
