What does Edward Abbey believe will happen if the dam is shut down and the reservoir is drained?

What reason does Edward Abbey give to prove that he is the best person to comment on the harm the building of the Glen Canyon Dam has done to the land?

If the Three Gorges Dam's reservoir was not constantly replenished from upstream its level would fall as power was generated. A low water level in the reservoir indicates:

What are dams and how do they help us in conserving and managing water?

Which of the following passages from Edward Abbey's "The Damnation of a Canyon" best demonstrates his use of ethos to build his argument?A.In the summer and fall of 1967 I worked as a seasonal park ranger at the new Glen Canyon National Recreation Area. During my five–month tour of duty I worked at the main marina and headquarters area called Wahweap, at Bullfrog Basin toward the upper end of the reservoir, and finally at Lee's Ferry downriver from Glen Canyon Dam.B.Lake Powell, formed by Glen Canyon Dam, is not a lake. It is a reservoir, with a constantly fluctuating water level more like a bathtub that is never drained than a true lake.C.The difference between the present reservoir, with its silent sterile shores and debris–choked side canyons, and the original Glen Canyon, is the difference between death and life. Glen Canyon was alive. Lake Powell is a graveyard.D.One should admit at the outset to a certain bias. Indeed I am a "butterfly chaser, googly eyed bleeding heart and wild conservative.

Edward Abbey's "The Damnation of a Canyon":For those who may think I exaggerate the contrast between the former river canyon and the present man-made impoundment, I suggest a trip on Lake Powell followed immediately by another boat trip on the river below the dam. Take a boat from Lee's Ferry up the river to within sight of the dam, then shut off the motor and allow yourself the rare delight of a quiet, effortless drifting down the stream. ln that twelve-mile stretch of living green, singing birds, flowing water and untarnished canyon walls — sights and sounds a million years older and infinitely lovelier than the roar of motorboats — you will rediscover a small and imperfect sampling of the kind of experience that was taken away from everybody when the oligarch and politicians condemned our river for purposes of their own.Which rhetorical technique is Abbey using in the underlined section of this excerpt?A.Ad hominemB.LogosC.PathosD.Ethos
