Unsustainable fishing is the most pervasive of all local threats to coral reefs.
Reefs at risk from overfishing and destructive fishing.
Marine-based sources of pollution and damage threaten approximately 10 percent of reefs globally, with only about 1 percent at high threat.
Globally, more than 60 percent of the world’s coral reefs (about 150,000 sq km of reef) are threatened by local activities (overfishing and destructive fishing, marine-based pollution and damage, co
This figure provides a summary of the four individual local threats (overfishing and destructive fishing, marine-based pollution and damage, coastal development, and watershed-based pollution) and the
Approximately 370 observations of coral bleaching were reported globally between 1980 and 1997, while more than 3,700 were reported between 1998 and 2010.
The world’s coral reefs cover an area of approximately 250,000 sq km, with the highest concentrations in Southeast Asia and the Pacific.
One-eighth of the world’s population—roughly 850 million people—live within 100 km of a coral reef and are likely to derive some benefits from the ecosystem services that coral reefs provide.
The assessment of the adaptive capacity of countries and territories to reef loss is based on economic resources, education, health, governance, access to markets, and agricultural resources.
Performance standards could cover up to 54 percent of U.S. greenhouse gas emissions. The pie chart above depicts all U.S. greenhouse gas emissions in 2008.
