🌊Dams block water flow, sediment, and nutrient flow, disrupting ecosystems.
🐟Removing dams allows fish to migrate and restore river ecosystems.
💰Maintaining dams is expensive, and it is often more cost-effective to remove them.
🌿Old, outdated dams that serve no purpose should be removed to restore natural habitats.
🚧Dams that are no longer beneficial can be hazardous and should be removed for safety reasons.
Why are dams harmful to ecosystems?
—Dams disrupt ecosystems by blocking water flow, sediment, and nutrient flow. They also hinder fish migration and disrupt food chains.
What are the benefits of removing dams?
—Removing dams allows fish to migrate, restores rivers, and promotes healthy ecosystems. It also saves costs on dam maintenance.
Are all dams outdated and harmful?
—Not all dams are bad. Some serve essential purposes like water supply and flood control. However, many dams are old, outdated, and no longer beneficial.
Why should we prioritize dam removal?
—We should prioritize dam removal to restore natural habitats, promote biodiversity, and enhance the health of ecosystems.
What happens to the water after a dam is removed?
—After a dam is removed, the water flows freely, resembling the natural state of a stream or river. This restoration benefits the surrounding ecosystem.
00:06Free-flowing creeks are the circulatory system of landscapes, forming vital ecosystems.
01:26Dams block water flow, sediment, and nutrient flow, disrupting ecosystems and food chains.
01:57Maintaining dams is expensive, and it is often more cost-effective to remove them.
02:00Old, outdated dams serve no purpose and should be removed to restore natural habitats.
06:42Many dams in the Hudson Valley and Northeast are aging and no longer beneficial.
11:04Dams of any size can block fish migration and disrupt aquatic ecosystems.
12:28Removing barriers for fish migration is essential for restoring rivers and fisheries.
14:00Removing a dam allows fish to fulfill their natural spawning and migration processes.
