How do humans affect the arctic?

Answer 1

AnswerWhen humans move vehicles or walk across the soil or the little vegetation it has, it destroys the permafrost and vegetation just moving the Tundra farther back in the succesion progress.

They introduce invasive plants and animals to compete with the endemic provenant ones for growing space.

Answer 2

We have set up a few science stations on the continent to monitor the weather and study the history of our climate. Very stringent regulations have been placed on the use of these facilities. We do not even allow dogs to wander the area.

Through global warming the ice is melting, especially in the West Antarctic Peninsula. In other areas the temperature is still extremely cold, too cold to melt ice.

Answer 3

Humans have invented machines such as the air-conditioner, cars and other hi-tech devices. These all run on energy provided by fossil fuels. Fossil fuels are burnt to obtain energy, and giving out carbon dioxide in the process. Burning of petroleum also causes a release of carbon dioxide into the air. Greenhouse gases are also given out by industries. These will lead to greenhouse gases trapping heat rays from the Sun on Earth, causing the temperature to rise. The ice caps at the Arctic will melt due to the heat. Animals living in the Arctic will experience heat and a smaller habitat as ice caps are slowly melting away. A lack of food will also lead to animals dying from starvation.

Answer 4

humans are affecting polar as the global warming has something to do with it......

Latest data shows an increase, not a decrease, in polar ice. The last two winters have been far below normal in temps, casting doubt on the theory of global warming.

Answer 5

by leting carbon dioxide in the air too much and affecting the earth's temp.

Answer 6

Humans contribute to pollution of the world. Due to this earth gets warmer including the arctic circle. The increasing temperature affects the arctic and and animals that inhabit it.
