The campaign was promoted on social media. Its purpose was to raise awareness and action against the consequences of human activity on the ocean’s health, as 95% of the ocean’s surface has become more acidic since the late 1980s. The acidification of the oceans is dangerous to the marine ecosystem and affects more than three billion people who depend on the oceans for income and diet.
