Food for thought

The International Energy Agency has said that the US will become energy self-sufficient by 2035 and is counting on massive expansion of the technique of fracking shale to get oil and gas. Sounds good but, as usual, it comes with a price. In this case environmental -- what happens to water tables, for example? The drilling industry refuses to disclose the toxins included in the fluid injected into the shale but it is known (Toronto Star, Dec 8, 2012) that it contains the carcinogens benzene and formaldehyde. This and a host of other problems will not stop the mad search for more oil and gas (and profit) as long as we tolerate this system. John Ayers
