The time is the third weekend of September.

World Cleanup Day (original English name: World Cleanup Day) is an international social action dedicated to responding to the world's uncontrolled land garbage and marine garbage problems by affecting changes in human behavior patterns.

There is no central organization for World Cleanup Day. This event is achieved through the efforts of grassroots people in different countries.

Participants in World Cleanup Day are mainly volunteers, and NGOs sometimes help them influence the public, coordinate activities, and raise funds.

With the development of industrialization, the amount of industrial waste and domestic garbage is increasing day by day, and the limited self-purification ability of the earth can no longer withstand the increasingly heavy pressure.

For example, our commonly used foam fast food lunch boxes cannot decompose on their own. For the earth, they are a kind of "white pollution" that can never be eliminated.

Everyone must start from me, don’t litter, reduce energy pollution, and keep the earth clean.

World Clean Earth Day is now one of the most important environmental protection activities in the world. More than 125 countries and 40 million people participate in this event every year.
