Worldwide populations are estimated to be between 10,000 and 25,000 animals, about 10% of what they once were.
Why is the whale population decreasing?
The species struggles due to impacts from humans. Entanglement in fishing gear, vessel strikes, and the shifting distribution of food sources as a result of climate change plague the whales.
What will happen if whales go extinct?
What is this? Whales play an important role in stabilizing the aquatic food chain and reproduction of other species. As more whales are killed, the ocean’s food distribution becomes destabilized and causes changes in the food supply of many other kinds of marine life.

The group said this is the lowest population number for the species in nearly two decades. In the past decade alone, researchers said, the species has declined by 30%.
How important are whales to the ecosystem?
Whales play a vital role in the marine ecosystem where they help provide at least half of the oxygen you breathe, combat climate change, and sustain fish stocks. How do they do it? By providing nutrients to phytoplankton.
How many endangered whale species are there?
Unfortunately, there has been a continuous decrease in many population of the whale species. The population decrease is so great that most of the whales are becoming endangered. Below are 17 Endangered Whale Species. There are also explanations on the factors that threat these marine mammals. 1. Sei Whale
What is the biggest threat to the whale?
Human impacts—specifically entanglements in fixed fishing gear and vessel strikes from ship traffic—remain the biggest threats to the survival of this species. Whales are at the top of the food chain and have an important role in the overall health of the marine environment.
Why are blue whales endangered?
The Blue whale was once heavily hunted for more than a century. This act almost drove the whale species to become extinct. From then on, protection took place for the endangered Blue whale so the species can recover. Another reason for its population decline is the fact that the Blue whale is too powerful to have any predators.
