Environmentalists are Cargo Cultists
Cargo Cults were belief systems developed by primitive tribes to make sense of parachute resupply pallets that missed their mark in World War 2. They found the bounty, had no easy explanation for how the goods arrived, and so designed a religion that ascribed these things to God. Environmentalists suffer from a similar misunderstanding about what they see in the world today. The actual explanation is easy to see, if we look at what is happening with open eyes.
The planet has changed, and it will continue to do so. Humanity has emerged as the apex predator in recent years, and we hope to remain at the top of the food chain for a long time to come. We humans need food and energy, and are fantastically gifted with the ability to provide it for ourselves. The Cargo Cultists and their ilk believe humanity to be vermin in a formerly "pristine" environment, who have ruined the optimum environment that existed before we ascended to primacy. There are too many of us, they believe, and we live too well, devouring too much food and energy for the planet's good, or something.
That is fatuous nonsense. We humans are here to stay, and our numbers are bound to increase. Pretending that yesterday's fish species or yesterday's climate is somehow "optimum" is merely a political talking point with no basis in fact or science. The political class wields these ideas to amass great power and wealth. I understand and respect where they are coming from. They know exactly what they are doing, and have no compunctions, or conscience, about it.
What I cannot respect is otherwise intelligent people buying in to these notions of peak oil, global warming, or endangered species. These changes are all natural, they have been happening for more than four billion years. There is no reason to believe that the earth will mot survive for billions years more as a fecund environment for whatever species have the hardiness and will to cling to life here.
Me? I'm betting on humanity. If the wild salmon can't make it in the real world, we will just have to find a better fish to eat. I see no danger in a warmer climate, even as I doubt that we shall see one. We are not that lucky - we may well have to deal with the cold. Air is cleaner every year, even as gas, oil, and coal are more abundant today than ever before. Victory will go to the bold, which pretty well describes humanity. Those who would cower in cold drafty caves instead of gleaming edifices because they fear the unknown can do it without me. Al Gore apparently agrees with me on that last point, for himself, at least.
