Damming Rivers

Should humans continue to construct dams, or not?  What do you feel are the strongest arguments supporting your point of view?


      I think that dams serve many good purposes. They provide recreational areas for boating, skiing, camping, picnics, etc. They also help prevent the loss of lives and property to be caused by flooding. Dams also create reservoirs that supply water for all kinds of purposes. 10% of water used for irrigation is stored behind dams, which creates jobs. It is also a sufficient way for hydroelectric power resources to stay clean. Dams also provide stable inland river transportation systems.
      But, still considering those perks, I don't think (certain) dams should continue being constructed. As for areas like in the Three Gorges Project, there are animals that have very essential and specific habitats. It is nearly impossible for them to become acclimated to new living conditions. If the dam were to be built, the animals, like the Balji Dolphin whose only natural habitat is the Yangtze River, would have to be transported elsewhere, where there are no promises that he nor his peers would adjust and live an average-length life.
      As for the people living near/on the soon-to-be dammed river, they would have to be "transported" also. They would be reimbursed for their houses, that would have to be torn down. It would be the value of their house at the time, but despite this, could make it difficult to buy a new home. The money they were given may not be enough to start over nor pay for a new house in the area they've been moved to.
      Jobs, though some will be created when the dam is built, will also be wiped out. Thousands of farmers not able to receive new land as compensation, would be trained for jobs in cities. But because the relocation numbers are so high, the odds of restoring their livelihoods are low.
      When the houses are destroyed, forests and agricultural lands will also be depleted. This will lead to erosion and sediment build up at the base of the river and reservoir. This could in time lead to increased flooding upstream.
