Letter: Climate and the human factor
Mankind does have a part in global warming and climate change.
Crude oil, natural gas and coal-fossil fuels -- is stored energy from the sun. In the past century it has become the lifeblood of mankind and has made it possible for the world population to grow to nearly 7 billion people.
The environmental consequence of this is that mankind has added trillions of tons of carbon dioxide to the earth's atmosphere.
The predictions by some scientists say that crude oil, natural gas and easily mined coal will be mostly gone in 30 to 40 years.
It's then that Mother Earth will slowly begin to heal herself from man's overuse of stored energy.
