How conservation and preservation affects polar bears

Conservation

Conservation is an effort to keep nature beautiful and everlasting. Conservation can help ensure that land will not be degraded to a point of no return. Examples of conservation include bans and hunting. Both are used to limit or increase a resource or animal.

Preservation

Preservation maintains pristine wilderness by blocking off human interaction. Bans on hunting, fishing, fires, and cutting down trees are all examples of preservation. Keeping someone from building a dam(affecting fish) is another example of preservation.

How conservation and preservation affects polar bears

Polar bears are endangered and vulnerable due to hunting, global warming, ect. There is an estimated 20,000-25,000 polar bears in existence. Polar bears live in northern areas where it's cold, such as Canada, Alaska, Greenland, Russia, and Norway. Hunting was a major threat to polar bears in the 1960s and 1970s, and is a small threat today. The international Agreement on the Conservation of Polar Bears was signed in 1973, which banned polar bear hunting. Today, the greatest threat to polar bears is loss of their sea ice habitat due to human caused climate change. The ice in these areas is melting because of rising temperature due to greenhouse gas emission. We can help preserve their habitat by reducing the amount of greenhouse gasses, which will stop the increasing temperatures.
