The ocean is now a key element in climate negotiations. There are some 250,000 species that live in the waters of the planet. So many species, not counting flora, which are directly threatened by climate change. With us, the most visible effect is the bleaching of the corals. 80 to 90% of our corals are no longer viable. But there is also talk of migration of marine species and a drop in catches, compared to 30 years ago. NGOs and authorities agree that change must come from us, citizens, and that requires increased awareness.
