How does pollution affect whales?

Answer 1

Global Warming effects the whales by moving the Frontal zones (whale food areas) farther away. As global warming melts the sea ice, it also makes the frontal zones warmer. Global warming also messes up the warm currents that the whales normally swim in. Due to global warming, krill is dying out, and so there are less krill in some areas. For example, in California, the krill population is decreasing , so the whales along there have to look elsewhere for food. This causes the whales to get off track and loose their ways. Whales would follow the warm current and the krill. When whales migrate, to get to their frontal zones, it takes them a long way. If global warming moves those frontal zones, the whales would have to travel even farther. All this put together equals whales having to travel longer distance for food, less time for feeding, more competition for food. The frontal zones provide the whales with lots of nutrients and krill. This is their primary food source.

One must ask themselves if Whales care if they travel further though or if 0.5 degrees per 150 years years causes whales that much extra travel over a single year.

Man killing krill it would seem would have a far greater impact on where krill are for whales.

Answer 2

As the water temperature is rising, other whale species that are usually living in more temperate waters are now moving up North, forcing Belugas and Narwhals to either share their food and habitat with them or retire to regions located to higher latitude regions.

Answer 3

if global warming gets worse, the icecaps will melt and the creatures the seals eat will go extinct. without food, the seals will die out as well.

Answer 4

it causes the water temperature to rise and make the water uncomfortable for organisms to live in
