Sea Shepherd is fighting against krill trawlers in Antarctica, which threaten marine life like whales and seals that rely on krill for survival. These massive fishing vessels disrupt feeding areas and have even caused the deaths of several whales. With scientists onboard, Sea Shepherd documents these activities to gather evidence for protecting these waters. The group aims to halt the industrial fishing that damages the fragile ecosystem and calls for new marine protected areas. Their efforts seek to raise awareness and encourage public action to protect the Antarctic environment.
