Where do my Environmental ethics lie?

Biocentrism. Id have to say that i'm a team player as they say. I care deeply about the environment, and try and reduce my footprint on mother nature as much as I can. I Know that my impacts will affect other systems around the world. If you look at global warming for example, our increased burning of fossil fuels is having a effect on the planet. We burn fossil fuels to make our human lifes easier, but it is having a negative effect on other species and organisms, that share our environment.

What gives us the right to cut down forests to build homes, when in fact that same forest already was a home, home to wildlife, organisms, an entire ecosystem.
