They are a big-time ecological problem in fact, when all the unpleasant side effects are factored in.

It all depends on who you ask Dennis.. Uncontrolled torential floods that strip away topsoil and cause massive erosion, also create massive ecological problems. And it's usually as an effort to control such massive flooding that projects liket TVA, and Three Gorges in China, are launched.

And for every person displaced by most hydro-projects, you'll probably find 1/2 dozen others who have jobs that did not exist before.

But that said.. Dams built in the wrong place, and with poor designs, are a menace. This was clearly the case when dozens of dams burst in China, killing over 1/4 million people in the resulting floods.

In places like the Amazon, the worst I see happening is the resevoir silting up and filling it in, which would then be consumed by the rain forest. And the dam would eventually be forced to open it's spillways dozens of years from now when (if?) this happens.

But I'm with you. I would rather see new nuclear technology used, and more dependence upon fuel reprocessing/reenrichment, so less has to be buried.
