Study: Plastic pollution is harming photosynthetic bacteria in the ocean that produce 10 percent of the oxygen we breathe

Marine microorganisms may also be threatened by plastic pollution in the ocean. Since one type of photosynthetic bacteria accounts for 10 percent of the oxygen production on Earth, we need to take steps to protect the microbes before we run out of breathable air. Australian researchers issued a warning following their recently published study. They reported that toxic chemicals leaching out of plastic waste harmed the oxygen-producing bacteria Prochlorococcus. Not only did the chemicals halt the photosynthetic activity of Prochlorococcus, but the toxins also hampered the bacteria’s growth. Read more....
