It's very easy to get judgmental. You know: corporations, you're bad; environmentalists, you're good. It has that polarizing effect. And then nobody respects either. What I want to say to corporations is: A dead planet is bad for business. Your business model falls apart when everybody is dying. And from the environmentalist point of view: how do we go about feeding and clothing and housing seven billion people and try to keep all that in check? We have no choice but to engage in technological innovations.
