What I said, specifically, was: Personally, I place more value on an entire species of bird (eagle, osprey, etc) than I do on the number of lives lost to malaria. That's a matter of personal philosophy, however. It has nothing to do with science. Unadulterated BS based upon a ridiculous book written by an overwrought Green with no expertise in the field. "Silent Spring" indeed. What bird species were "wiped out" in the US during the extensive use of DDT to control mosquitoes? What I said above is all I said. I didn't say that any species was wiped out (although it seems quite certain that a number of raptor species were well on their way, and that because of the overuse or misuse of DDT). BTW, I also said that I wasn't opposed to the use of DDT, and that most of the problems it has caused have been the result of years of misuse (which not only resulted in the near extinction of some valuable species, but also produced a high level of resistance in mosquitoes and may ultimately result in more human suffering). Even if the massive turbines wipe out "an entire species" of migrating birds? Well, that's why we are wise to consider the environmental effects of large projects. My position would be that if enough birds were killed to cause a species to go extinct (particularly a very distinct species), an extremely high value would need to be demonstrated by the project. More than I think could reasonably be shown. If the overall population of the bird species was only slightly or moderately affected, such a project might well be acceptable. You can't honestly believe there's a valid argument here? We don't have the physical resources to build enough wind turbines to measurably reduce the energy from any wind pattern. And you base this statement on ????? Common sense. Winds near the ground are the lowest speed winds, up to tens of kilometers high. Turbines only extract a few percent at most of the wind energy, and only from a fairly small cross section of the total volume of the farm. And the biggest farms we could build would cover only a tiny fraction of the Earth's surface. Any small forest or mountain is obviously going to have a much greater impact on wind patterns than a turbine farm. There are any number of environmental tradeoffs to consider when it comes to wind power generation, but the effects of removing a bit of kinetic energy from natural air currents is not one of them. Specifics please. What have been the results of environmental studies on the deployment of massive wind farms as espoused by the Greens? Have there been ANY studies? Of course. Even the most cursory web search would answer that question. Wind farms are evaluated for their impact on birds and animals, on their effects on groundwater, on secondary effects from the transport of power, on their true efficiency based on the energy cost of building and maintaining the turbines, and more. _________________________________________________ Chris L Peterson Cloudbait Observatoryhttp://www.cloudbait.com Ah, selective clipping of my message, responses consisting of banal generalities and selective answers-the last resort of those spouting nonsense. |
