Summary:
- Orcas, also known as killer whales, are facing significant threats along the coast of British Columbia, Canada. Researchers have found that the population of these marine mammals has declined by 30% over the past two decades.
- The main reasons for the decline include a lack of their primary food source, Chinook salmon, as well as increased noise pollution and vessel traffic in their habitat. These factors have made it more difficult for orcas to find and catch their prey.
- Conservationists are calling for urgent action to protect the orcas, such as reducing boat traffic, improving salmon populations, and addressing other environmental issues that are impacting these iconic marine animals.
