The Post’s argument in favor of exporting natural gas at Cove Point on the Chesapeake Bay in Maryland [“Why Cove Point should get busy,” editorial, May 7] ignored the potential impacts of hydraulic fracturing on communities and water supplies. This is typical of the “energy at any cost” thinking that has leveled mountains in West Virginia, created oil spills in the Gulf of Mexico and created dead zones caused by nuclear contamination in Chernobyl and Japan.

“Fracking” is a dirty business, and there is much evidence that it can cause contamination of water tables — the lifeblood of many communities. Why should energy companies be encouraged to engage in this practice for profit that only a few will realize? Instead, what’s needed is a global commitment to reducing energy usage and expanding renewable sources.
