Ocean Acidification: The Basics

The pH scale is shown on the right. Carbon dioxide is naturally present in tiny amounts in the atmosphere; however, since humans started burning fossil fuels at the beginning of the industrial age, carbon dioxide levels have increased dramatically. Carbon dioxide is a gas that plants combine with energy from the sun to create food. It is also a greenhouse gas: it traps the heat of the sun and keeps it from reflecting back into space. Today the oceans absorb about 25 percent of the CO2 released every year. Scientists use the pH scale to measure the concentration of hydrogen (H) ions in a solution on a scale of 0 to 14. Ocean acidification takes place when excess CO2 from the atmosphere dissolves in the ocean and combines with seawater to form carbonic acid.

Protecting Sustainable Resources. Startling Images of the Tons of Trash in the World's Oceans. <br/><a href=" ABC US news</a> | <a href=" World News</a> Copy Nearly 270,000 tons of plastic are floating in the world's oceans, according to a new study.

That's divided into at least 5.25 trillion plastic pieces, researchers wrote. Or, enough to fill more than 38,500 garbage trucks, the Associated Press reported. "Plastics of all sizes were found in all ocean regions," said the report, published on Wednesday in the scientific journal PLOS ONE.

Researchers only measured plastic floating at the surface of the oceans, and not at the ocean floor, and the study doesn't take into consideration any of the other trash polluting the seas.
