Bill are you in town this weekend? I would like to get out to your school again soon and learn from you if you are able. Can't bring little Ben though as a 360 mile round trip is more than either of us can tolerate right now.

Trust me, in the end the environment will win. The Sun is part of our environment/ecosystem and all stars have finite life spans. Current estimates are that within 1 billion years the Earth will become uninhabitable due to changes in our middle-aged Sun's life cycle. Within 5 billion years the Sun will swell up to a red giant the size of the orbit of Mars, thus either consuming Earth or ejecting it out of the solar system. Either way, if humanity is still around in a billion years it will need to upgrade that fly-to-the-moon ability into flying to a habitable planet in another solar system, if such a planet can be found or created (or possibly create some non-planet living-arrangement options). And then how long will the new planet or other arrangements last?IJ wrote:I wouldn't say, however, that humans have a "role," in the environment. When PETA asks their dogs to eat vegan, that's dumb. But humans have moved beyond biology. We may have been hunter gatherers for the most part, but now we can fly to the moon. We can meet all out needs nonviolently--if we choose. And if they want to live vegan lives, power to em. We're not obligated to fulfill our former role in the environment. This is evident every time we get into our plastic and electronic and refined steel and glass machines and drive to work at computer plants and oil refineries and dam rivers and reshape ecosystems. Those things aren't bad per se, but they illustrate how a little thinking has moved us permanently beyond the laws of the forest.
