How industrialization by humans can destroy natural habitats

How industrialization by humans can destroy natural habitats

Explanation:

The author emphasizes how much the scenario has changed for Glen Canyon and the Colorado river due to human intervention. He narrates in explicit detail how different it looks like now compared to how it was back in 1959, the year when he went on rafting trip to the Canyon with a friend. He explains that the sole purpose of the dam they have built there is to provide entertainment for the middle class and above as those kind of people use motorboats to move about. This dam has drastically changed the wildlife in that area, specially around the river. The author even states that it would be much better if the dam was destroyed so that nature could restore itself.
