What are two negative impacts of building dams?
Dams change the way rivers function. They can trap sediment, burying rock riverbeds where fish spawn. Gravel, logs, and other important food and habitat features can also become trapped behind dams. This negatively affects the creation and maintenance of more complex habitat (e.g., riffles, pools) downstream.
What are the best alternatives to dams?
Ans. The two alternatives to big dams are: Recycling/Reuse of water: One of the ways of doing so is reusing or recycling the water. By recycling or reusing, we mean the process of sewage treatment.

How do dams destroy ecosystems?
Dams store water, provide renewable energy and prevent floods. Unfortunately, they also worsen the impact of climate change. They release greenhouse gases, destroy carbon sinks in wetlands and oceans, deprive ecosystems of nutrients, destroy habitats, increase sea levels, waste water and displace poor communities.
Why do large dams destroy ecosystems?
Large dams cause environmental damages to rivers, hydrologic basins and surrounding ecosystems, including: the worsening of water quality in rivers; the degradation of aquatic ecosystems and the disappearance of many riparian ecosystems; and serious harms to biopersity, including the extinction of species.
Why are dams so dangerous?
Understanding Dam Incidents While all dams are potentially dangerous, low-head dams are especially dangerous because the water around them often appears to be tranquil and inviting. Many drowning victims deliberately jump from or float over them without knowing the risks.
