Hetch Hechy.

Situated in the mountains of Yosemite Park, we come across a quiet, peaceful almost scenery surrounding what is known to be called Hetch Hetchy. Before we get started, Hetch Hetchy is one of San Francisco's main source of water. All the water we obtain from San Francisco comes from the reservoir in Yosemite Park. This reservoir is the cleanest source of water in SF, don't think twice about drinking the tap water from SF, because the tap water is clean and quite tasty. Since 1913, the city of San Francisco approved the o'shaughnessy dam which has been built with 300 feet of water. Unfortunately, this dam has factored to many environmental impact for the Yosemite Park. Within ten years Hetch Hetchy will be covered with large amounts of dry land and dead plants due to the dam. This issue has many surrounding debates on whether government should remove the dam or keep it there. If we take out the dam, we can restore Hetch Hetchy to it's original state. Taking the dam out will cost lots of money and San Francisco won't have a source of water. This debate is a huge case, especially in my environmental science class. Soo..this is my question..should we or should we not remove the dam from Hetch Hetchy? Or perhaps leave it for economic purposes? It's quite a compelling question, but i'll leave the debate up to you guys..
