Water and marine environment

Change language

All life on our planet - including our ecosystems, society and economy - is dependent on water. Marine and freshwater ecosystems have many vital functions: filtering, diluting and storing water, preventing floods, maintaining the climate balance at local and global levels, safeguarding biological diversity.
