I sure hope you wrote this message on a device that was naturally made and not assembled from materials (metal, glass, plastic) that were extracted from their natural ecosystem. We humans manipulate "natural" ecosystems all the time, and have from the dawn of time. We risk extinction as a result of these manipulations. But many of the things we take for granted nowadays are the result of ecological manipulations. Ever rode a horse in the Americas? You took advantage of an ecological manipulation. Ever eaten corn grown in Europe? You took advantage of an ecological manipulation. Ever used electricity that comes from a dam? You took advantage of an ecological manipulation. My point is this: man has manipulated ecosystems on a massive scale previously. I'm not going to say that what this guy is proposing is a good idea, but I'm also not going to dismiss it simply from the perspective that "Human intervention in the natural ecosystem is always inherently bad" either. This is where science comes into play. I'd like to know more about what it says on this subject.
