英文摘要	As lockdowns took effect to slow the spread of coronavirus disease 2019 (COVID-19), the global demand for petroleum collapsed. As a result, oil prices plummeted, making the manufacture of virgin plastics from fossil fuels less expensive than recycling ([ 1 ][1]). This cost incentive, along with lifestyle changes that increase plastic use, has complicated the challenge of overcoming plastic pollution. During the pandemic, personal protective equipment (PPE) has driven increased plastic pollution. In response to high PPE demand among the general public, health care workers, and service workers, single-use face mask production in China soared to 116 million per day in February, about 12 times the usual quantity ([ 2 ][2]). The World Health Organization has requested a 40% escalation of disposable PPE production ([ 3 ][3]). If the global population adheres to a standard of one disposable face mask per day after lockdowns end, the pandemic could result in a monthly global consumption and waste of 129 billion face masks and 65 billion gloves ([ 4 ][4]). Hospitals in Wuhan, the center of the COVID-19 outbreak, produced more than 240 tons of single-use plastic-based medical waste (such as disposable face masks, gloves, and gowns) per day at the peak of the pandemic, 6 times more than the daily average before the pandemic occurred ([ 5 ][5]). If the increases observed in Wuhan hold true elsewhere, the United States could generate an entire year's worth of medical waste in 2 months ([ 6 ][6]). Individual choices during lockdowns are also increasing plastic demand. Packaged take-out meals and home-delivered groceries contributed an additional 1400 tons of plastic waste during Singapore's 8-week lockdown ([ 7 ][7]). The global plastic packaging market size is projected to grow from USD 909.2 billion in 2019 to 1012.6 billion by 2021, at a compound annual growth rate of 5.5%, mainly due to pandemic response ([ 8 ][8]). This global health crisis puts extra pressure on regular waste management practices, leading to inappropriate management strategies, including mobile incineration, direct landfills, and local burnings ([ 9 ][9]). Improper disposal of just 1% of face masks translates to more than 10 million items, weighing 30,000 to 40,000 kg ([ 10 ][10]). Waterlogged COVID-19–related plastic has been observed on beaches and in water ([ 11 ][11]), potentially aggravating the challenge of curtailing microplastics. At the regional and national levels, prioritization of human health over environmental health has led to the delay or reversal of policies aiming to reduce single-use plastic ([ 9 ][9]). As a result, demand for recycled plastic material has dropped, the profit margins of recycling have decreased, and the environmental footprint of plastics has increased ([ 9 ][9]). We need urgent and coordinated commitment to circular economy approaches, including recycling practices and strict policies against plastic pollution. Companies should continue efforts to curtail virgin plastic use and increase plastic recycling to live up to their corporate social and environmental responsibilities. Without a concerted effort to protect the environment during and after the pandemic, we are unlikely to meet the United Nations' Sustainable Development Goals ([ 12 ][12]). 1. [↵][13]1. A.
