Threats To Wild Killer Whales
Populations of whales, dolphins and porpoise off the coast British Columbia have experienced dramatic changes since industrial humans expanded here in the 1800s. Whaling had a significant impact on killer whales. These factors are the main reason killer whales in B.C. are now at risk for extinction, while current and emerging threats have an even more harmful impact on these species. These threats include food supply, toxins, entanglement, depredation, noise, collisions with vessels, boat disturbances and continued whaling.
