The fact that they're still running at all is an enormous success.
The New York City subways were built in 1903. Q: You talk about how quickly it would take the infrastructure of our cities to disintegrate, and recently, we've had an underground steam pipe explosion in Manhattan and a bridge collapse in Minneapolis.so how do those incidents fit into your discussion?ĪW: The fact that the infrastructure is falling apart is not necessarily because it's built poorly. We don't have to make excuses for our existence. It took us a lot of work to evolve to this point, but we should be in much better balance with nature than we are right now. We deserve to be here as much as any other species. Some of our acts of expression are so beautiful. we have done some truly wonderful and original things that no other species has done, like we've written Beethoven's 9th. Our methods used to fit neatly into the ecosystem in a way that humans got plenty of food and other species in the ecosystem also got plenty of food. before our agriculture was so vast, we used to do agriculture in a more sustainable way in that it didn't overwhelm nature or use tons of chemicals to make things grow faster. Q: You ask, "Is it possible that, instead of heaving a huge biological sigh of relief, the world without us would miss us?" Well, would it?ĪW: Here are a couple things to think about:
It's absolutely simple and cheap technology. But one thing we could be doing is making it a law (like it is in Israel and Cyprus) to take every building eight stories or under and heat all of the water in those buildings with solar energy.
Solar and wind are intermittent and they're so diffuse, it's difficult to harness them in a significant way. One of the reasons I think the population question is important, if we want to be as green as possible, any of our energy that is truly renewable is limited.
