Rising water temperatures

The risk of facing bleaching events is increasing and alarming. When the seawater temperature rises, it can upset the symbiosis between the coral polyp and its algae. The algae become toxic for the polyp which therefore expels it. Without the algae, corals lose its main source of food and its color turning skeletal white. If the conditions don’t improve, corals are likely to die. The warmer our climate gets, the more likely the coral will bleach and die.

Ocean acidification

The ocean absorbs around 30% of the carbon dioxide (CO2) of the atmosphere. The more CO2 the atmosphere releases, the more acidic the ocean becomes. The rising acidity of the ocean makes it harder for the corals and other marine organisms to form and properly build their calcium carbonate skeleton. This situation makes them more vulnerable.

by 2050

Half of the world’s coral reefs have already been lost or severely damaged. If nothing is done, coral reefs will be the first ecosystem on Earth to entirely collapse, dragging with it the loss of 25% of marine life that rely on them.
