In this scenario, every time a person sneezes, one unit of garbage disappears from the oceans, so that during the cold season, the waters of the seas and oceans are considerably cleaned.
However, not just any sneeze will do, only those spontaneously generated by the body. To provoke them using something that activates the sensitivity of the nose, will not have the same effect.
The most valuable will be those of people who are responsible citizens, without criminal records and with some profession or trade, so the incentive towards education and training in people will be taken with much more responsibility by governments, who are the only ones who know the power of sneezing to preserve the planet and somehow reverse the consequences of global warming caused by pollution.
