Ocean acidification is increasing due to rising CO2 emissions from human activities like burning fossil fuels. The ocean's pH has decreased by 30% since the industrial revolution, threatening coral reefs and marine life. Coral reefs support about a quarter of marine species and over a billion people rely on fish and the ocean for food and livelihoods. Individual actions like reducing energy usage, recycling, and voting can help address ocean acidification and its impacts.

Ocean Acidification
pH Scale - 0 to 14, 7 is neutral - Logorithmic (black coffee is about 7 times the acidity of milk) - 8.2 to 8.1 since the beginning of the industrial revolution - Acidity increased by 30%
Coral reefs are home to nearly one fourth of all marine species and they provide places to find food, safe locations from predators, and areas for reproduction

Ocean Acidification
- About 1/4 of worldwide human protein consumption is provided by the ocean - In Asia, about 1 billion people rely on fish as their primary source of protein -There are about 200 million people worldwide employed in the fishing enterprise
Ocean Acidification
CO2 Emissions - Our energy-related activities account for about 他 of human CO2 emissions - Caused by the burning fossil fuels. -Deforestation is also a major factor of CO2 emissions; plants and trees can absorb CO2
