Oceans: reservoirs of biodiversity

About 70.8 % of the Earth's surface is covered by oceans. This huge reservoir of biodiversity is home to millions of species. Three researchers, Gilles Le Boeuf, Nadine Le Bris and Nathalie Niquil, explain the impacts of climate change on the marine environment.
The multiple alterations caused by humans weaken ocean ecosystems and undermine their role as natural climate regulators. These far-reaching changes, which affect the abundance and diversity of marine species, have an impact on the food webs of these environments and on human populations.
