Hardly. They are constantly preaching the "Peak Oil" scenario.
Yes you are correct, that is what they preach. Oh Doom and Gloom we are using up all of the Earth’s resources!
However the actions of government that they advocate create conditions that would cause great reductions in the availability of gasoline. Rather than encourage the discovery of new sources of mineral wealth they advocate severe reductions in mining and drilling.
Yet famous Liberal advocates of restrictions on traditional fuels use are some of the most blatant profligate users of traditional fuels.
The Liberal in essence wants to have gasoline available for them to use but doesn’t want anyone else to have gasoline.
Liberals practice magical thinking. Hypocrites.
