Why is the humpback whale on the endangered species list?

Answer 1

The most common reasons for the Humpback Whale's listing on the US Fish and Wildlife Species Endangered List is due to over commerical hunting/fishing, entanglement in fishing nets, collision with ships, distrubance of migration routes by shipping vessels, radar and sonic testing in migration and protected areas, decline in food supply from over fishing or global changes. There are several other factors, such as solid waste dumped at sea, ocean temp. changes, etc, but many researchers can not agree on their actual influence.

People used to go whaling or whale hunting, but now that is against the law in most countries.
Because of Hunting. Man has severely affected humpback whale populations by killing them for years. By the 19th century, many nations (USA in particular), were hunting the animal heavily in the Atlantic Ocean, and to a lesser extent in the Indian and Pacific Oceans. This widespread hunting sharply reduced whale populations.

It is estimated that during the 20th century, at least 200,000 humpbacks were taken, reducing the global population by over 90%, with North Atlantic populations estimated to have dropped to as low as 700 individuals. To prevent extinction, the International Whaling Commission banned commercial humpback whaling in 1966. By that time the population had been reduced to around 5,000. That ban is still in force

Answer 3

The most common threats to the Humpback Whales are commerical fishing/hunting, net entanglement incidents, collision with ships of all kinds, pollution, including dumping solid waste in the oceans, and reductions of their food supply due to any number of reasons, including over fishing, and global warming. To add to their problems is the changes going on with water temps. and testing radar and other sonic equip. in their migration routes.

Answer 4

I think they are endangered because people are illegally hunting whales and that most of them have been killed because of that.

Answer

The biggest threat to humpback whales wasn't/isn't illegal hunting, but rather legal hunting.

And before whale hunting got banned they were killed by the thousands, and being quite slow breeders, the population still hasn't recovered and isn't anywhere near recovering yet.

Answer 5

The humpback whale is threatened as it has been over-hunted by the whaling industry. It is sought out by whalers as it travels along its regular migratory routes. The problem was particularly rife prior to the introduction of a whaling moratorium in 1966. Until the moratorium, humpback whale figures had dropped by around 90%.

After the ban, their numbers are increasing.

Answer 7

They are threatened for their meat and blubber

Answer 8

hump back whales are not endangered
