In the third grade I learned in school that natural resources are not infinite, Robert. It was over 60 years ago, yet that realization continues to remind me that the actions of each individual can effect the health of the Earth. It’s a collective process. The EPA has some information: http://www3.epa.gov/climatechange/science/causes.html
What made you believe that Climate Change isn’t real?
God didn't make enough to last until He returns, or what? Nothing that happens here is "collective" except in the sense that we are all sinners. But, that doesn't have anything to do with your dedication to your grade school education. That stands alone as an example of humanism.
There is nothing man can do to destroy the earth. Portions, yes, but not all. If the land becomes poisoned (for example by your blessed EPA spill), then man makes reparations to the land.
Climate change is not real, in the sense that "we are doomed". Most of us old folks have figured out that it is more commonly called "weather". Some times it is cold. Some times it is hot. Some times it rains. But, it always different than what the forecasters say it will be!
The climate always changes. What many don’t believe is that it is primarily man made and that we need draconian measures to take over every aspect of our lives to change things.
