Which effect increases as plastic debris accumulates in ocean gyres experiencing stratification?

💡 Explanation

When plastics accumulate in stratified gyres, increased UV exposure interacts with the plastic surfaces because less vertical mixing occurs, accelerating their breakdown via photolysis and releasing harmful chemicals. Chemical breakdown via photolysis results, rather than mixing, CO2 absorption or reduced bioaccumulation, which have opposing or unrelated factors.
