"The idea of zero impact ought to be non-controversial. It is simple common sense that practices which are unsustainable cannot continue, and we know that it is true that propping up unsustainable practices with non-renewable resources has even more dramatic consequences. And we are currently growing rapidly less sustainable, and using more and more non-renewable to keep the ecological consequences at bay. This must stop. All of this is just plain speaking, and ought to be obvious to any informed observer...
"...I, for one, do not believe that we must be worse off for this transition. Under most models, the economy will continue strong growth even if we push hard on reducing emissions -- indeed, many of the things we need to do will actually improve productivity, more than paying for themselves. (This is true, by the way, not just for carbon emissions, but for toxics, waste reduction, water conservation, ecosystem service preservation, greater access to education and health care and host of other sustainability priorities). On pure GDP terms, making this transition quickly may be a huge winner.
"And, of course, GDP isn't everything. There are a whole host of human security, moral happiness and quality of life questions that tackling this crisis will help us answer. If we move quickly, we could not only have staved off disaster by mid-century, but built a profoundly better world. And that is far more than nothing."
Yet another voice extolling the fact that making the planet happier will make the people happier.
