Thank God for the Earth, and thanks to the Earth for petroleum and the products ingenious humans have created with it! This product of nature frees me to work where I work doing the job I have chosen, and those plastic grocery bags kept me from buying a Diaper Genie, are my luchbox, gross garbage (like a week-old bird carcass) picker-upper, and will be recycled!
Richer countries pollute less. So, if we've exported production and the pollution that goes with it, we need to export capitalism to increase the standard of living in those countries so they pollute less, I guess.
