Corals, the basic structures of coral reefs, are affected by the increasing acidity (decreasing pH) of the oceans. When the ocean absorbs carbon dioxide, the carbon dioxide reacts with water and other
substances to form carbonic acid. This process uses substances in the ocean that corals use to build
their skeletons. So, the more carbon dioxide there is in the ocean, the harder it is for corals to build their
skeletons. Ocean acidification can also destroy existing coral reefs.
1. Give two possible ways that negative human impact on the pH of Earth’s oceans can be reduced.
2. Conduct research to learn more about your proposed solutions. Be sure to look up information about cost, safety, reliability, and social or cultural implications when applicable. What are the pros of each solution? What are the cons of each solution?
3. Which solution would be better to implement? Justify your answer.
4. What sources did you use?
