Dams Have Huge Enviornmental Impact
There are bigger environmental issues with dams. All but the very smallest have a system of dams and tunnels. They gather silt behind the dam wall, blocking the flow of nutrients and wildlife downstream. Over 45,000 hydroelectric dams have been built averaging more than one a day last century - fragmenting many of the worlds major rivers. They are an environmental catastrophe in wildlife terms, but thats not the half of it.
