  3. I think that building the Glen Canyon Dam was a bad idea because rare plants and animals have gone extinct, it slowed down erosion,and lots of historic sights were lost.CF

  4. I think that biulding Glen Cayon Dam was a bad idea.Because we lost of historic sites and old artaficts. But also because it caused a lot of fish and plants to go extinced. Last of all because it slowed erosion wich is not good.

  7. I think it mas a good idea because more people could live on the other side of the dam. And it helped plants and animals more than made them wores I think. And because it gave people electricety,flood control,and irregation wator.

  9. I dont think that they should have Glen Gran Canyon because plants and animals are getting extinkt. And alot of history got drenched in water.And also slowed down the Colorado river. And slowed down erosion.

  14. I think the Glen Canyon Dam shouldn't have been built because tons of historical sites were lost,the canyons were flooded,it slowed erosion,it slowed CO. River,plants and animals have gone extinct,and ruins were flooded.

  27. I think that building the Glen Canyon Dam was a bad idea because it is causing species of plants and animals to go extinct, historic sites were drenched, and more. Even though the lake provided electricity, irrigation water, and flood control. I think that people could live without all those things. And if they wouldn't have built it it wouldn't have slowed down the Colorado River.

  43. No, it is not a good idea because there's more reasons to say its not a good idea. It slowed down the Colorado River. Also, the water is very cold and the animals are not used to it. The fish can't lay their eggs so they might get extinct soon.

  47. I think that is was a good idea because it gave us electric power, irrigation water, flood control, and Lake Powell fun. But I also think it was a bad idea because there was less water downstream, slowed the Colorado River, the canyons were filled with water, a lot of historic sites were covered with water, and plants and animals have gone extinct.

  51. I think it was a bad idea to build the Glen Canyon Dam because there is less water going downstream Arizona.The fish need warm water and rightnow they are in the cold water so they can not lay there eggs.Animals need water to drink and the water is cold so the animals can not drink it

  52. I think no they should not leave it up. Because even though there is one more reason to leave it up but sevral animals dying because of the cold water being let in from the botom so fish cannot lay there eggs.

  56. Conclusion:

    I think it was a bad idea to build the Glen Canyon Dam because we have better and more reasons in the no column. Even though it caused "fun", it was still a bad idea. I think this because people are not as important as animals. Some of these animals were extinct. Every reason in the yes column had to do with humans. And people back then did not even relize they where hurting nature, and they were not only hurting nature, but the flood had flooded a lot of famous monuments and they were lost. This is why buiding the Glen Canyon Dam was a bad idea.
