1. Habitat loss: The destruction of seals' natural habitats, such as ice floes and coastal areas, is a major threat to their survival. This can be caused by human activities such as pollution, development, and climate change.
2. Hunting: Seals are hunted for their fur, meat, and blubber. This has led to the decline of many seal populations, particularly in the North Atlantic.
3. Climate change: The effects of climate change, such as rising sea levels and changing weather patterns, are also threatening seals. For example, sea ice is melting away at an alarming rate, which is affecting polar bear populations.
4. Entanglement: Seals can become entangled in fishing gear, leading to injury or death.
5. Disease: Disease outbreaks can affect large numbers of seals and can contribute to the decline of seal populations.
