- Hunting: Beluga whales are still hunted by some indigenous peoples in the Arctic, and this can contribute to population declines.
- Pollution: Beluga whales are exposed to a variety of pollutants, including heavy metals, pesticides, and oil spills. These pollutants can harm the whales' health and reproductive success.
- Climate change: Climate change is affecting the Arctic ecosystem, which is home to beluga whales. This can lead to changes in the whales' food supply, as well as increased exposure to toxins and disease.
- Shipping: Increased shipping traffic in the Arctic can disturb beluga whales and displace them from their traditional habitats.
- Noise pollution: Noise pollution from human activities, such as shipping and seismic surveys, can disrupt beluga whales' communication and ability to find food.
All of these factors are thought to be contributing to the beluga whale's slow recovery. More research is needed to understand the specific impacts of each of these factors, and to develop strategies to mitigate their effects.
