Reading the article, I think the issue of existence is a misplaced priority coming from economist. I would be more comfortable if its coming from environmental activists, association of people weather readers or people concerned with global warming but not economist who don't have issue with the creation of more vehicles in other to increase GDP and increase standard of living, they also don't have issues with felling down of trees for the sake of development forgetting the advantage of a green environment, they also don't consider the impact of factories emission, release of toxic into the sea all in the name of reducing unemployment but raising concern about mining activities like they care about the environment.

Their real concern is because all of the theories, consultancies that makes them forever relevant in the scheme of things is going to be relegated to the background if the continued dominance is unabated so they decide to attack from the disadvantages they can lay claim to.
