It makes me so sad to think about how humans are messing up the planet for every other species. I kind of feel like if it were only oyrselves that we were destroying, then it would be terrible, but somehow a fair cop. Unfortunately, in the process we're putting every other sentient species on the line.
I just can't comprehend why so many people feel like humans are somehow more important, and more entitled than every other being, and that it's okay for us to wreak environmental devastation and multiply out of control. I strongly believe that we should be aiming for negative human population growth - no more than one child per person. On a planet with finite resources, we simply can't continue to grow ad infinitim - we will hit a brick wall sooner (I fear) or later.
