1. Overfishing and Bycatch: Whales are often caught unintentionally in fishing nets meant for other species. This "bycatch" is a significant threat, especially for smaller whales and dolphins. The depletion of fish stocks also impacts whales' food supply, further endangering them.
2. Habitat Loss and Degradation: Whales rely on specific habitats for breeding, feeding, and migrating. Pollution, oil spills, and coastal development are destroying and degrading these habitats, impacting their ability to survive.
3. Climate Change: Ocean warming and acidification due to climate change are disrupting whale ecosystems. This affects their food sources, migration patterns, and overall health, making them more vulnerable to disease and threats.
These are just a few reasons why whales are endangered. Other factors include ship strikes, noise pollution, and entanglement in marine debris.
