The dam itself causes no pollution but the submerged vegetation in the reservoir behind the dam can decompose creating methane, a potent greenhouse gas. To prevent this it would be necessary to remove all vegetation and organic rich soil from the area proposed for the reservoir down to a clay base (or install a non-organic base).

Does hydro energy cause pollution?
In reality no source of energy can be said as pollution free. when hydro electricity is said as a cleaner source of energy it means that it is "cleaner" that some other source of energy. example: hydro electric power is cleaner that petroleum since burning of petroleum produces harmful gases but not in case of hydroelectricity the pollution caused by hydroelectricity is the ecological imbalance . to produce hydro electricity dams are constructed. for construction the forest nearby is cleared and therefore causes soil erosions and other related problems. it causes ecological imbalance because when water from rivers are stored in dams it causes water shortage in rivers and affect marine organisms.
Do the non renewable resources cause pollution?
Biofuel, or biomass, is sometimes the burning of vegetation to produce energy. Burning, especially incomplete burning, can release smoke and other air borne particulates as pollution. The carbon dioxide released was only recently removed from the atmosphere (when the vegetation was growing) so it is not a pollution causing global warming. (This is why biomass and biofuel is counted as clean renewable energy.)
Does Garbage Cause Pollution?
Yes, garbage can cause pollution when it is not disposed of properly. Improperly disposed garbage can release harmful chemicals and greenhouse gases into the environment, contaminating air, water, and soil. It is important to manage and dispose of garbage responsibly to reduce pollution.
How does building dams help us to prevent erosion?
Building dams helps prevent erosion by regulating the flow of water in rivers, reducing the speed and volume of water that can cause erosion downstream. Dams also help to stabilize river channels and can create reservoirs that store sediments and reduce erosion. Additionally, controlled release of water from dams can prevent flooding events that can worsen erosion.
Can pollution cause earthquake?
There is no known evidence of pollution causing earthquakes. However, earthquakes can inadvertently cause pollution by damaging areas that contain waste facilities, factories, or other places that may contain waste or chemicals that are dangerous to the environment.
What are 2 positive point and 1 negative point about dams?

Can wind cause pollution?

What are the primary reasons that lake sturgeon is endangered?
Habitat loss, overfishing, building of dams and pollution.
Dams cause what type of pollution?
Dams can cause several types of pollution, primarily through the alteration of water quality and ecosystem disruption. They can lead to nutrient loading, which promotes algal blooms, and the accumulation of harmful substances like heavy metals and pesticides in stagnant water. Additionally, the decomposition of organic material in reservoirs can produce methane, a potent greenhouse gas. The alteration of natural water flow can also impact sediment transport, affecting aquatic habitats and water quality downstream.
How does matter cause pollution?
Matter does not cause pollution. Human beings do.
What are the fossil fuels that do not cause pollution?
There isn't any fossill fuels that don't cause pollution. All fossil fuels cause pollution.
Is their pollution and flooding or any other problems in the River Nile?
The flooding has all but been solved by dams, but there is a pollution and other problems. The links below addresses just one aspect of construction and a paper on pollution
Why is the cherry salmon endangered?
Over the last two centuries, dams, overfishing, excessive logging, shoreline development, pollution, and industrial water withdrawals have degraded rivers, streams, and oceans critical to the salmon's survival. Dams and pollution are hazards for the Atlantic salmon on its run to the spawning beds.
How do plastic bags cause pollution?
they cause pollution because it is harmful to the environment.
