What does the author use in this passage to support the idea that the dam has ruined Glen 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. In 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.

Answer:

A description

Explanation:

In these lines, the author describes the experience of travelling on a boat on the river. He tells us that if we were to take a trip on Lake Powell  followed immediately by another boat trip on the river below the dam, we would realize what a huge impact the dam has had on the environment. The author describes the scene in careful detail in order to form an image in the mind of the reader and in this way make a more persuasive argument.
