They release greenhouse gases, destroy carbon sinks in wetlands and oceans, deprive ecosystems of nutrients, destroy habitats, increase sea levels, waste water and displace poor communities.

Why is it dangerous to swim near a dam?

The reason for the danger is the circular motion of the water near the dam. When the water flow is strong, it flows over the dam with force. This forms a continuous circle of water, called a hydraulic, from which even the strongest swimmers often cannot escape. They are circulated up and down until they drown.
