Key Facts on Oceans and Coasts
- More than 90 per cent of the world's living biomass can be
found in the oceans.
- Coral reefs, which rival rainforests in biodiversity, are
being destroyed through siltation, coral mining, illegal poaching
with explosives and pollution.
- More than 3.5 billion people depend on the ocean for their
primary source of food. In 20 years this number could double to
7 billion.
- More than 40 fish stocks are already over-exploited or depleted
worldwide.
- The total harvest from commercial, subsistence and recreational
fishing now exceeds the estimated maximum sustainable yield of
100 million tons per year.
- By the year 2000, annual fish supplies may fall short of demand
by about 10-15 million tons.
- Of all marine habitats, those that are most threatened are
in coastal waters, where 90 per cent of the world's marine catch
come from.
- An estimated 21 million barrels of oil run into the oceans
every year from street runoff, ships flushing their tanks and
effluent from industrial facilities.
- An average of 600,000 barrels of oil has accidentally spilled
from ships into the ocean each year over the last decade.
- Six countries-the Russian Federation, Japan, Spain, Poland,
South Korea and Taiwan-are responsible for 90 per cent of high-seas
