Ocean carbon cycle
Without the contribution of oceans and coastal ecosystems to global biological carbon
sequestration today’s CO2 concentration in the atmosphere would be much larger than
it is. But the uptake capacity of oceans and coasts is both finite and vulnerable. Minimisation
of pressures, restoration and sustainable use are management options that can help
these ecosystems maintain their important carbon management function.

Marine species diversity
Limited information is available on species diversity and the condition of coastal and marine ecosystems (Burke et al., 2001). There is growing evidence that many marine species are less widely distributed, and therefore more vulnerable to extinction, than previously thought (GESAMP, 2001a). The protection and sustainable use of marine resources and biodiversity are governed by several international conventions, including the Convention on Biolog...
