Excellent additions, Miles and Master.
One note. Global Climate Change is, of course, quite real. Our climate is in constant flux. Change is the only constant.
Man's infuence? That is the scam. Learn some math.
How much energy would it take to raise the GMT, Global Mean Temperature, by one degree celsius?
How much energy does mankind produce in all its activities?
The answers will astound you.
We couldn't effect the global climate if every human in existence dedicated his entire life to the effort.
Life is tenacious, rapacious, and utterly ruthless. "Fragile" is just about the most inaccurate word one could posibly find to describe our world.
Does that mean we rape and pillage the natural world without regard to the future?
Of course not. We do possess the means to drive some species to extinction. We could fundamentally alter the appearance and composition of the biosphere's eco-diversity.
However, responsible stewardship involves not wasting energy in counterproductive, "feel good" measures that actually require more use of the living spaces around us.
Responsible stewardship means using less of the natural world.
Find our energy in the atom, not our forests and open spaces.
Use our arable land efficiently to wring every calorie possible from every cultivated acre, better wild prairie, than enless miles of corn and wheatfields.
Look up and down, into the sky and the cold, dead ground. Skyscrapers better than sprawling suburbs. Mining and drilling better than cutting and clearing.
We have spent milennia developing the means live extravagantly without having to destroy our natural world. Yet those who claim to champion it cry out for the very methods that would bring its destruction.
Humans are the dominant species on this planet. We will eat, and breed, and live our lives just like every other lifeform. Those who think that salvation lies in some sort of self imposed, slow, collective suicide: "Don't consume. Don't advance. Just sit still and try not to use anything," are welcome to remove themselves from the gene pool. That is the way of death.
I will look to the night sky for our future. We are destined for the stars. The Universe will Let us know in no uncertain terms when we overstep our bounds.
Until that day, we are obligated not to consume less, but to produce more with less. More energy from a tiny mass of fissile material. Not miles of solar panels and wind mills requiring millions of tons of materials and vast quanties of energy to produce and maintain. Build our cities high into the sky, not outward into sprawling suburbs with ridiculous, inefficient gardens and stupid green buckets at the curb, filled with waste products that will consume more energy being transported than required to produce new.
Nature is worth preserving for its own sake. Not Doomsday prognostications.
