- The resulting ocean warming and acidification have added to other pressures on marine life, such as pollution and over-fishing, and the populations of many species are shrinking or shifting in response.
- The Congress is also expected to decide on motions dealing with regional approaches to tackling the global problem of marine litter, and on the protection of marine and coastal habitats from mining waste.
