ere we found, from laboratory experiments, that plastic debris leachates decrease seawater pH, especially if the plastic is aged and exposed to weathering for a long time. Sunlight radiation enhances the release of DOC by plastic, leading to seawater acidification. Acidification is thought to be due to the release of organic acids, as well as CO2, from plastic. The concen- tration of plastic used in our experiments was similar to that observed in relatively polluted bays, but lower than in many highly polluted areas such as the Mumbai coast. It is particularly in these areas where plastic debris could magnify surface acidification with consequences for marine organisms and the biogeochemistry of DOM. pH decreases due to plastic degradation could reach up to ~0.5 units, a change comparable to that projected for the end of the century in the surface oceans due to anthropogenic emissions. Does the assumption in the last sentence of the Discussion seem reasonable to you? Why? Group of answer choices Yes. Organisms can lose calcium carbonate at the same rate at any pH level. Yes. The exposure to plastics in the other studies need to measure pH and note if it also impacts the organisms' health. Yes
