I view our success as a product of evolution. It is the driving factor that got us down out of the trees, cultivating our food and to where we are today.
Would we be putting a little less pressure on the environment without people like Edward Bernays, possibly. However, I think our collective consciousness can put itself a little at ease. As we enter the 6 mass extinction event, it's a natural cycle and if it wasn't us, some other species would dominate the planet.
It's never a bad time to listen to George Carlin's "saving the planet"
