Why is too much Carbon Dioxide in the oceans bad?
When carbon dioxide (CO2
) dissolves in seawater, the water becomes more acidic. This is a problem for many of the creatures that live in the ocean. It makes it harder for corals to build skeletons and for shellfish to build the shells they need for protection. Corals are particularly important because they provide homes for many other sea creatures. What happened at Bikini Atoll?
After World War II The United States carried out nuclear tests in the Pacific Ocean near Bikini Atoll
. After people became ill, Katsuko and her colleagues went to investigate. They found that if the testing continued the entire Pacific Ocean would be contaminated. They helped to stop above ground nuclear testing.
