Transcript of The Aral Sea "Shrinking"

The Aral Sea "Shrinking"
In the 1960's The Aral Sea is evaporating, because it is losing water, the Amu Dayra has been dammed off. Some scientists predict that the sea could be totally gone by 2015.
Food Chain
There are no living organisms in the Aral sea due to water loss, so this food web will be representing the organisms that were in the ecosystem 30 - 40 years ago
Nitrogen/Carbon Cycles
The carbon cycle is effected and interrupted when the decomposing animals and plants are compacted and compressed into the polluted sea bed. Since there are no plants in the sea bed and no animals to eat the plants so the carbon cycle, the sea bed becomes a pool.
How can food web and symbiotic relationships can be re-established?
Description of Ecosystem
The Aral Sea is drastically decreasing in size due to irrigation. Native species and other species are either moving away or dying quickly. The Aral Sea provides important ecosystem services including fishing stocks and preservation of surrounding water and oil quality.
Succession
The dry sea floor (Aralkum desert) is the largest area worldwide where a primary succession takes place. It has continued for 40 years.
Symbiotic Relationship
Loss of biodiversity
Disruption of ecosystem services
Fisheries
Climate regulation
Drinking water
Desertification
Impacts on animals and plants

How Abiotic Factors can be restored?
1. Installing desalination plants
2. Conserving rivers that flow into the Aral Sea
The nitrogen cycle is affected because there are no plants or animals that come onto the polluted sea bed. So there is no organic material that bacteria can turn into nitrogen. So the soil is a reservoir for the nitrogen cycle.

By: Hannah Walker & Mariyah Qazi
By creating new systems to prevent long term irrigation, to continue and try to maintain where and how the water from the rivers that connect to the Aral Sea is being used. Redirecting the rivers to the Aral Sea. Planting plants and getting animals to migrate back to create a new ecosystem. Get water to start flowing and getting the Aral sea to reach its potential. Carelessness is what will bring the Aral Sea to vanish completely. It is necessary to be aware.
Financial impact of the Aral Sea shrinking
Decline of fishing industry, decreased use of the sea as a transportation, loss of irrigation for crops in the area around the sea.

Description of Disaster
Redirecting water from the rivers to restore the Aral Sea is estimated to be at least 20 to 30 years, and the cost (in dollars) approximately $30-50 billion
