Long and thoughtful post from Worldchanging . An excerpt to give you the flavour:
'We can't simply plan to cut our own impacts down to a level that could be shared by everyone over the next four or five decades. Even if we had that long a time to reduce our impacts -- and we don't -- there is no way the rest of the word can get stable and sustainably prosperous in that time frame unless we lead the way right now. Anything less than an all-out effort now is morally inexcusable. Small steps, incremental reductions, slow plans -- unless these are tied to big, systemic and quick solutions, they will not be enough. We need a bright green future, right now.
All that is the bad news.
Here's the good news: We can build that bright green future. We have the technological prowess, the design insight and even many of the working examples we need to transform our systems and reinvent our cities. We have the money. We may even be gaining the most needed components, vision and political will.
Here's the better news: Not only can we build it, but we'll be better off when we live in it.'
