Imagine you’re a conservation scientist. Currently, all the electricity in your area comes from the burning of fossil fuels. The mayor wants to build a hydroelectric dam on the riverbank. The river is home to many species of fish, and it’s surrounded by thick woods that are filled with different types of wildlife. You’ve researched how a hydroelectric dam functions and are concerned that the dam will have damaging effects on the region’s biodiversity.
