Your problem, not mine. First of all, I did indeed say that government involvement has something to do with the reuction in pollution. Of course the article does acknowledge that government regulation was also helpful in this area. It's really a combination of better technology and government laws. But you need the economic growth in order to be able to pay for the better technology.
Government regulation does indeed have a lot to do with the reduction of pollution.
But the other things had nothing to do with government. The increase in the number of calories that are available per person is because of modern technology in the farming and food production industries. The increased availability of oil, copper, gold, silver, iron, aluminum, lead, zinc, etc., is also because of better technology that was developed by private industry. And Paul Ehrlich's claim that overpopulation causes poverty is utter nonsense. Africa has the best natural resources of any continent, and most of the countires in Africa have relatively low population densities.
