Green Energy

Yes, I was a but cynical also for the sake of conciseness, but there is indeed and interesting point in green cities, that's one question on which ecologism and environmentalism differ. The question is whether you are trying to preserve the whole ecosystem or an environment in which humans feel good.

To be honest, I don't want to live in a concrete jungle. I think inhumane to live in a super dense city totally disconnected to nature. But I also would like that we collectively accept that this is a preference that is harmful to the ecosystem and that it is sometimes okay to have such preferences, if we manage to make them sustainable.

20 years ago a urbanist I was working with, when we were doing city simulations to help offset CO2 footprint told me "you know, the ugly truth is that if we want to lower our CO2 emissions to the max, we should all live in skyscrapers on top of a school, supermarket and incinerator."

Thing is, we need to recognize the tension between an enjoyable environment, wildlife preservation, human health, the ecosystem's health... And we need to see further than the current, petty, political compartimentalization of these questions. I wish one day we start consider these questions a bit more seriously
