how is fishing killing polar bears, making them closer to extinction?

Question

How is fishing killing the polar bears, like taking thier food away but i need a bit more detail, can anyone help please
..x..Emz..x..

Why do you say WOW ?

Answer 1

Well, if you OVERfish our seas (which the fishing industry is doing) it is REMOVING the main food source for polar bears. if they don't have enough food, they starve - and that is how fishing kills polar bears.

Answer 2

Polar bears eat seals, not fish, but the seals eat fish, so in that way I guess you could say that fishing is bringing them closer to extinction. The main problem for polar bears is the dwindling polar ice cap - in other words - the warming trend presently obvious in the high arctic. Polar bears hunt for seals from the ice, so less ice, less hunting territory for bears.

Answer 3

1. Look up information about polar bears -- where they live, what they eat, and how much they need.
2. Also look up information about seals, which I believe the polar bears find quite tasty.
3. Look up information about the commercial fishing industry in those same areas, and how much fish they take of the kind that the seals (and perhaps the bears) would eat.
4. Put both together in a sensible way, and you'll have a decent report!

Answer 4

With fishing people catch the fish that are the lower end of thier class of fish. The fish that are "dumb" enough to go for the bait and the ones which are the least likely to survive. With the easy catches gone a polar bear has to work even harder to get the fish that is more fit to survive against predators making it that a polar burns more calories to catch the meal than that the meal is going to satisfy.

Answer 5

Eh?

News to me. With the exception of the Alaskan Fishing Fleets, I don't know of any other "Cold Water" fleets, so commercial fishing would have little to no effect on the polar bears, as their entire food chain is north of normal fishing grounds.

Answer 6

Polar bears primarily eat seals. Seals need fish to live. No fish, no seals, No seals and you get hungry Polar Bears.

Answer 7

Don't have any statistics for ya', but keep in mind that the most dangerous predator on the face of this earth be MAN!! Definitely not tryin' ta' be a smart A _ _, but unfortunately homo sapien be the biggest threat for the demise of nature itself! Do not like that word (demise), but if we allow it to continue at the rate it's goin, that will be the end result.

Answer 8

not many animals live in the same area as polar bears, that's why they sit on the ice by a hole and "fish" out of it. when the fish popluation decreases, so does their food supply. And polar bears aren't the fastest creatures, making it hard for them to catch jackrabbits and the other small, but faster, land animals.

Answer 9

What more detail is there to give?

The fishermen get the fish, so there are fewer fish for the polar bears to get. Period. End of story.

Answer 10

I'm sure the perch, bass, bluegill, catfish, and trout I catch in Massachusetts aren't affecting the Polar Bear populations in the Arctic

Answer 11

well , it's like me taking your meals away, you'd not last long..

over fishing means, that fish don't have time to re-fresh their numbers.. thats why they have quota's to stop over fishing..

remove something from the food chain. and it has a knock on effect...

take even the spiders... bats eat spiders... spiders catch flies..

without them there would be horrid flys everywhere.
