The protected areas now total over 100,000 hectares, including reserves and wildlife refuges in both countries and the biological forest corridor that protects the reservoir.
How many people died building the Itaipu dam?
As negative effects, we can mention the displacement of 10.000 families and the death of 149 workers during the construction, besides many other accidents and diseases. From a very controversial project, Itaipu became a very important source of energy to support Brazilian economic growth.
Why is hydroelectric dam bad?
Building dams destroys the natural defense system that healthy rivers give our communities. Hydropower dams can contribute to global warming pollution: When a forest is cut down to make way for a dam and reservoir, those trees are no longer available to absorb the carbon dioxide added by fossil fuels.
What are the benefits and the drawbacks of building Itaipu dam?
