//** Summary: **// As global warming makes the sea ice more scare, Polar bears are finding it much harder to catch seals to eat. For other species of bears, summer is a feasting period. But for Polar bears, it is a time of hunger. The sea ice during the summer will retreat, making it harder for the Polar bear to find food. Because of this, they try to gain as much weight as they need to carry them through the summer in the spring. According to Dr. Bechshoft, the spring is pupping season for seals, which means they just lay on the ice waiting for the Polar bears to come. But less sea ice means the Polar bears will have to walk or swim more in search of food. Every additional mile that the polar bear has to travel using its own power is also power needed be recovered by eating more seals.

//** Relation to the course: **// The cause for the melting of the arctic ice is global warming. Global warming, or climate change, is a phenomenon where levels of certain greenhouse gases, such as methane and carbon hydroxide cause the rise of the average temperature of earth’s climate(Miller 501). Measurements reveal that the surface temperatures of nine stations north of the Arctic circle have rise above 5.5 celsius 1968(Miller 503). Since 1947, the average temperature have risen by 2 degree celsius, and 5 of the 9 massive floating ice shelves surrounding the continent have broken up since 1950(Miller 503).

Dr. Bechshoft commented on the issue: “No sea ice, no polar bears, it’s really simple.” I think it is absolutely true. There has been numerous studies that prove global warming true, and its effect on arctic ice. The arctic ice is necessary for the survival of Polar bears, as they allow the Polar bears to hunt seals to survive. The number of Polar bears is already decreasing, and were previously listed as a threatened species in the US under the Endangered Species Act in as early as May 2008. It is not just Polar Bear’s that will be affected by the melting of sea ice, all of the animals in the food chain will be affected. Vegetations that grow on ice in the arctic will disappear, which leads to the break down of the chain. The biodiversity of the Arctic will decrease overall drastically. In order to protect the sea ice, we need to increase awareness of the situation and decrease the levels of greenhouse gases released into the air.
 * My Opinion **

The Paris Climate Agreement: The nations of the word have to limit global warming to no more than 2 degrees Celsius above pre industrial levels. If we reach a more ambitious 1.5-degree target, then we might allow sea ice to survive year round.
