Illegal fishing, oil tanker spillages, floating fields of plastic bottles spanning kilometres: We have caused a lot of damage to our oceans in recent decades—damage with far-reaching consequences for marine life, for the balance of Earth’s ecosystems, and for humanity itself. The ocean is essential to the lives of billions of people, whether directly or indirectly. That’s why the Sea Shepherd Conservation Society has been dedicated to fighting the destruction of habitats and the slaughter of wild animals in the world’s seas for over 40 years now.
