Lomborg's taken plenty of flack for his views, and while his book is no masterpiece, he has a point with many of the things he says. And the spirit behind his argument, that we should be using our resources to improve people's lives as best we can instead of easing our conscience about the environment, is not off the mark.
At least in the US, we spend way more money building machines and maintaining armies that are meant to kill people in 3rd world countries. 3rd world countries also lack infrastructure that is required to move them towards better economies. Many times, this infrastructure is limited as much by history as it is by local geography. Not every country is blessed with the Great Plains.
There are also win-win situations, such as moving away from economically volatile fuels to sustainable sources like nuclear.
