Marine Rewilding: Restoring Ocean Ecosystems and Animal Welfare

Marine Protected Areas and active marine rewilding — restoring seagrass, kelp, and reef habitats — create refuges where marine animals can feed, breed, and shelter without fishing pressure.

Key Facts

Only 2.9% of the ocean is strongly protected — far below the 30x30 global target
Seagrass meadows support hundreds of species and sequester carbon efficiently
Kelp forest restoration in California has recovered in areas where sea urchin barrens were cleared
Fully protected areas show 4-6x more fish biomass than adjacent fished areas
MPAs benefit animals beyond their boundaries as fish populations spill over into adjacent areas

Welfare Considerations

Marine animals in well-enforced protected areas are free from the stress and mortality of fishing pressure. Fish in no-take zones show reduced wound rates, healthier body condition, and higher reproductive success. Restored habitat provides shelter, food, and breeding grounds that support individual animal welfare across entire communities. Marine protection is welfare infrastructure at ocean scale.
