Let's think twice about hard-to-get oil. Extracting oil from shale requires enormous amounts of energy (often derived from coal), adds to global pollution, and has not been proven to be economically viable.
Please, stop filthy oil shale production
Dear Representative
Hi. At least, let's think twice about hard-to-get oil. Extracting oil from shale requires enormous amounts of energy (often derived from coal), adds to global pollution, and has not been proven to be economically viable. I urge Congress and the President not to support oil shale refining unless it can be economically viable and minimally polluting. Thanx. Goodbye.
Matutinally Yours,
[Your name]
