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

- 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

CO2 Emissions- Our energy-related activities account for about ¾ 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

- Still relatively new- Many governments

unaware- Ideas of using alkaline

(high pH/very basic) too difficult

- Walk, bike, or take public buses- Recycle/reuse products- Make your home more efficient- Vote whenever possible
