I'm not a great fan of the Heritage Foundation however I happen to agree with the author on this occasion. 
If one is to believe what these so called "experts" predicted (peak oil) 20 years ago the world should have no oil today, yet today 20 years later we have more oil than we know what to do with.
Lets rather concentrate on immediate challenges that we CAN do something about such as deforestation, over-fishing and the Fukushima nuclear reactor spewing 100s of tons of nuclear toxins daily into the sea which sadly escapes the media's attention.
