Covering more than 70 percent of the Earth's surface, the world's oceans harbor fantastic biodiversity, feed over a billion people, employ hundreds of millions, enable passage for over 90 percent of global trade, increasingly provide energy for the global economy, and serve to inspire humanity in infinite ways.

Yet, oceans and the species that depend on them— including humans—face an uncertain future. The combined effects of overfishing, serial depletion of marine species, poorly managed resource extraction, rising seas, and warming waters have contributed to the loss of a third of the world's coral reefs, 90 percent of the ocean's top predators, and the collapse of its most productive fisheries.

While the ocean is vast, less than one percent is truly protected and the majority of marine biodiversity exists adjacent to our coasts—areas where human dependence is greatest and conservation efforts are needed most. Throughout the world, many countries lack sufficient capacity to conserve and manage the vast wildlife aggregations, marine biodiversity, and fisheries that are sustained in these near-shore waters.

The Wildlife Conservation Society (WCS) is filing this capacity gap by investing in ocean protection, sustainable fisheries, and marine species conservation across the waters of 23 countries and all 5 oceans. With several hundred marine scientists and conservationists on staff, WCS tests and applies innovative solutions for measurable conservation outcomes. Our core strategy is to:

  1. Protect Key Habitats
  2. End Coastal Overfishing
  3. Save Marine Mammals, Sharks and Rays

We support these core strategies with a strong foundation of science to discover, innovate and scale solutions, as well as outreach via the New York Aquarium to educate, inspire and increase political commitment for change.
