Will you ever read this article? Probably not. Will you ever read past the first page of Google’s reassuring results from various well-heeled green NGOs about any of the above questions? No. Will you ever stop to wonder how we eradicated malaria in the developed world using DDT and still have plenty of birds and the bees? No. Will you ever try to calculate how many lives have been saved by us being malaria-free for over half a century? No. Will you think about why we’ve spent 800 billion dollars to fight global warming when the Earth’s temperature hasn’t risen in nearly two decades? No. Will you consider the effect that amount of money could have had on poverty relief around the world? No."
