How has man affected humpback whales?

Answer 1

Dolphins have been effected in many ways as such; when people litter it gets into waterways and the dolphins and other animalschoke or smaller animals like birds get suffocated when the plastic of soda cans gets stuck around their neck. Also many dolphins get shot and killed for their fat or meat by fishermen. These fishermen then sell the meat and make a profit. this hold a major contribution on why dolphins are so endangered

Answer 2

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

Well, we nearly made them go extinct for starters.

Answer 4

basicly in weight you would need 2667 of them!

Answer 5

humans used to hunt them but that was banned in 1966 and now they kill the blue whales food which is krill. Without krill, Blue Whales can't survive.
