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
