How are melting glaciers controllers of the future environment?

Explanation: Today, the increasing temperature is causing ice caps on Mount Kilimanjaro and ice sheets in Antarctica and Greenland to melt (Lovgren 2004a) (see Appendix 2). This has resulted in the rise in sea level, causing many problems to the nature balance. Cold water fish cannot survive and even coral reefs are dying as the water is becoming too warm. This causes problems for people fishing them as a food source and influences the fisheries in general. Besides, Lovgren (2004b) said that the rising sea level can have serious impacts on low-lying countries, some of which like Indian Ocean’s Maldives or Nile Delta could be submerged. Not only will fishing be affected but people will also have difficulties in finding higher ground for living.

An imbalance in nature’s food chain would be caused by global warming. As ice sheets melt in the Antarctic, the polar bears would be adversely affected since the temperature is too warm for them to live. “Polar bears are entirely dependent on sea ice, you lose sea ice, you lose polar bears” (Malcolm 2004). Additionally, the seal and sea lion population that would otherwise be controlled by polar bears as part of their diet would multiply and overpopulation may occur, causing many fishes being eaten and depleted. This depletion affects fisheries and people living in the northern hemisphere because they must then find other food sources which would be difficult as their main source of protein and food are fish.

because it is in a high speed so it must move into a of high potential
