My statements are based on ecological impact to the earth. We need to stop adding CO2 to the atmosphere. We also need to stop pumping our sewage the oceans. Almost all the oxygen comes from the oceans. I saw the smog over Denver metro area last week. It was horrendous. So bad it gave me a cluster headache as soon as I got to the Tech Center area.
I have a electronics/physics background and have seen the devastation of the coral reefs in Florida as a scuba diver. We are slowly killing this planet.
