Hydroelectric dams

The construction and operation of hydroelectric dams involve significant environmental and ecological repercussions. Building these structures often utilizes concrete, with gravel sourced from pits, and the transport and construction processes rely heavily on fossil fuels, contributing to emissions.

Hydroelectric dams

The World's Oceans

71% of the Earth's surface is covered by water
The oceans contain 97% of the earth's water
All oceans and seas are actually one continuous body of water
Oceanographers are scientist who study the ocean and its processes.

Land the dam is built on

More dry land is created as parts of the body of water are sectioned off by the dam.

Additional info

Greenhouse gases

When a sea has no access to the ocean then it is known as a land-locked sea.

Dam reservoirs create Greenhouse gases from microbial process that decompose organic , but in some cases they can act as carbon sinks.

Water

The Pacific Ocean is the largest and deepest of Earth's oceanic divisions. It extends from the Arctic Ocean in the North to the Southern Ocean in the South and is bounded by the continents of Asia and Australia in the West and the Americas in the East.

Water tempter can be altered

Controls when the water flows

Over all O2 levels go down, With in the large body of water and further down stream.

Plants

The Indian Ocean is the third-largest of the world's oceanic divisions, covering 70,560,000 km² or 19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east.

Change water quality can kill the plants living there.

Can flood forests causing a loss of a major carbon sink.

animals

The Southern Ocean is the 'newest' named ocean. It is recognized by the U.S. Board on Geographic Names as the body of water extending from the coast of Antarctica to the line of latitude at 60 degrees South.

Habitat is changed drastically in unreversible ways.

Contributes to significant loss of aquatic biodiversity.

The dams prevent fish from reaching their breeding grounds, interrupting the food chain.

Manufacturing and materials

The Atlantic Ocean occupies an elongated, S-shaped basin between Europe and Africa at the East and the Americas at the West.
