For each factor described below, decide whether dams have an overall positive impact on it, an overall negative impact on it, or both positive and negative impacts on it. Part a: Drag each label to the appropriate bin. Dams have an overall positive impact on Dams have an overall negative impact on Dams have both positive and negative impacts - Reducing property damage from seasonal flooding downstream areas - Fish populations in the river system - Supplying sediments to downstream habitats - Supplies of drinking water and irrigation water for nearby cities - Recreational opportunities - Electricity generation - The risk of catastrophic flood damage downstream areas

Sometimes human actions can have both positive and negative environmental impacts.A negative impact of a large, hydroelectric dam is that it backs up water sometimes for miles behind it, destroying natural habitat that once was there. But a positive environmental impact of a dam is that A. large amounts of electricity can be produced, without contributing to air pollution B. beavers won't build dams of their own C. it produces a lake, which is great for water skiing D. it makes it easier for migrating fish to make it upstream to reproduce
