Oil and gas are commodities and as such are prone to boom and bust cycles. The defense of the left and eco crowd is the collapse of the price of oil, which conincidentally has been slowly rising and is now thought to be at the point of balancing supply and demand, with a gradual increase in price through to 2018. World demand for hydrocarbons is rising, not falling. Any argument otherwise is based on excuses, misrepresentation, wishful thinking about renewables that havent been built yet and outright hypocrisy.
