Humpback whales are incredible creatures that have had their populations threatened by human activities like whaling, fishing gear entanglement, and ship collisions. They play a key role in ocean ecosystems, especially through their long migrations and feeding habits, which help transport nutrients. Organizations like Sea Shepherd are working hard to protect these whales by intercepting illegal whaling, monitoring krill fishing, and establishing marine protected areas. Their conservation efforts are crucial for the survival of humpback whales and the health of our oceans.
