The future of the next generations is in our hands!
Coral reefs cover only 0.2% of the Ocean floor, yet they are home to 25% to 30% of the world's marine biodiversity. A 1 square kilometre reef produces on average 15 tons of food per year, and participates in local economies through fishing or tourism activities. It is estimated by the UNEP that 60% of the world's population depends indirectly on coral reefs.
Like other coastal ecosystems such as mangroves or seagrass, coral reefs are major carbon sinks that play a significant role in mitigating global warming. Like them too, they act as a natural barrier against climatic disasters and erosion: a reef reduces on average 97% the intensity of the waves for the coastal villages!
Coral reefs are therefore central ecosystems for our planet, which emit the oxygen we breathe (the Great Barrier Reef in Australia emits for example more oxygen than the Amazonian Rainforest!) and condition our survival as humanity. Yet it is estimated that we have lost between 30% and 40% of coral reefs irreversibly over the past 30 years.
