To celebrate the 10th World Cleanup Day on Sept 15, some 700 non-profit NGOs and social groups held activities aimed at cleaning up the environment and tackling the waste crisis throughout China, mobilizing an estimated 1 million-plus people. More than 13 million people from 155 countries and regions joined forces to collect man-made non-degradable trash, according to World Cleanup Day headquarters, which called the event "the largest peacetime civic action in human history". says Eva Truuverk, head of the managing board of the Let's Do It foundation, promoter of World Cleanup Day. "I collected more than 500 bags of trash, and that didn't even make 1 percent of the waste I saw along the way," he said in an interview with Xinhua after coordinating a World Cleanup Day activity in his native Jiangxi province. "Where there is a will, every day can be and should be 'Cleanup Day'," says Ma Yongjian, a volunteer from Beijing who recently did "plogging" - jogging while picking up trash - with his friends in Yudong Park in the northwest of the city.
