I have a slightly different take on the whole oil -v- climate debate.
If we don't economize significantly on our use of crude oil to provide fuel for road, marine and air transport, we risk either running out or running very low on stocks of this particular natural resource. Although most people think of crude oil in terms of petrol, diesel, heating oil and perhaps kerosene (the fuel used in aircraft), much of it is used as a feedstock for the chemical industry. Crude oil is the foundation upon which the world's chemical and pharmaceutical industries are built. Without it, many chemicals and medications would be quite simply impossible to synthesize. Without crude oil, most plastics would be completely unavailable and although substitutes using other raw materials are under development, for the time being, the overwhelming bulk of plastic production requires a crude oil input.
We will be doing future generations a gross disservice if, in our manic scrabble for growth at any price, we deprive them of a supply of one of the world's most ubiquitous feedstocks.
