Stop Hydropower Dams From Destroying Wildlife

Hydroelectric Dam

Target: Ernest Moniz, Secretary of the United States Department of Energy

Goal: End the use of human-made dams after it was found that they devastate biodiversity and threaten marine species.

Hydroelectric dams severely reduce biodiversity and threaten one third of all fish species in the area flooded by the construction, according to recent studies. It’s obvious that these human-made dams change the marine environment around the dam due to drastically altered water levels, but the effects are worse than anyone had predicted.

A study published in a recent edition of Biological Conservation found that the islands left behind when hydroelectric dams flood areas have shockingly low biodiversity rather than being the “wildlife refuge” pro-dam companies and individuals claimed they would be. Low biodiversity is a detriment to any ecosystem as it makes all species much more vulnerable to disruption and extinction.

This has clearly been the case around hydroelectric dams, where studies have found the numbers of multiple species of mammals, fish, reptiles, birds, invertebrates, and plants to have declined each year after a dam is built. This is consistent across every dam investigated.

Though hydroelectric dams don’t produce the same carbon as fossil fuels, they’re clearly not the answer if we truly want to protect the Earth and all living things on its surface. Sign our petition to urge the U.S. Department of Energy to stop building dams and create a plan to dismantle existing dams and reverse the damage done to nearby ecosystems.


Dear Secretary Moniz,

Recent studies have outlines the devastation caused by hydroelectric dams. Although it was originally thought that damage to local ecosystems and biodiversity, however it appears that the truth is worse than anyone had imagined. These studies are finding that numbers across species of all types of animals have been steadily declining each year after dams are built. The biodiversity on the islands left by the flooding from the dam is sorely lacking, threatening all species in the area.

Due to the decline of fossil fuels and findings on just how harmful they are to the environment, new, environmentally friendly energy sources have been developed to the point that they’re absolutely viable to support an entire nation. Solar and wind power are clean sources of power that don’t devastate nearby ecosystems and threaten the health of all species in the area. Please stop building hydroelectric dams and commit to focusing on safe, clean solar and wing power.
