Whoa Pilgrim!
How can you say I haven't pointed out anything which is truly serious? In my previous post I said, "And the will be's include extinctions of animal and plant species, deforestation of the world's biosphere, fish stock depletion, growing dead zones in the world's oceans, increased cancer gins in the world environment, air pollution, light pollution, and waiting for three light changes to get through an intersection." Do you mean to say that you really do not think that ever growning dead zones and fishstock depletion in worlds oceans are not serious issues. If so, then please tell what your definition of a serious issue is and give us one hypothetical exanmple?
While I try not to jump up and down about every little warning sign, there is an obvious and deliberate ignorance of past events that absolutely, positively, demonstrate that man has the capability to do two things:
1) Make an awful, ignorant, big mess.
2) Reign in his irresponsible, fellow humans to stop them from making big messes.
The dust bowl was just ignorance. They didn't know ant better. Now we do. We do things differently in most places where we want to keep our soil. Here in the upstate of SC, a similar result was experienced when cotton farmers left the land barren and all of our soil was washed away, for lack of cover. We can't grow crops here anymore and we likely never will, in any foreseeable future. These occurrences also disprove the notion that the Earth "fixes" or offsets man's actions. No one has yet seen the top soil replaced by the Earth in the dust bowl region or our region. It may happen, but not within centuries of it's original demise. Maybe a big flood will bring some dirt in one day.... I don't know.
The passenger pigeon is another great example. The American skies were once black with hoards of them. Men found that they were a good source to feed the labor and made pretty good stuffing for pillows, so, they would put out fermented grain and when hundreds of them were too intoxicated to fly, they would rush the field and club them by the wagon load. When early "environmental extremist" warned that they may kill off the entire species, they were laughed at and it was explained how arrogant it was of them to think that man had the capacity to wipe them off the Earth... how stupid could these "environmentalist" be?
Of course, the rest of the story is that "deniers" of man's capability to severely impact his environment, killed every last passenger pigeon they could find until..... they were no more. They did this in a remarkably short time. These birds, once the most populous bird species on the planet were extincted by man, the last one dying in 1914 in a zoo.
See... if you don't control these morons who think man doesn't have the capacity to have large scale impact on his environment, they will destroy pieces of it as they can. We have the evidence.
