![]() These lockdowns disrupted daily life worldwide, decreasing the level and frequency of human activity and production.ĬOVID-19 forced industries, businesses, and large corporations to shut down. As a result of the severity of the virus, most countries enacted lockdowns to protect people, mitigate the spread, and ensure space in hospitals. As of November 2021, the continuing COVID-19 pandemic had killed over 5 million people. By 5 July 2020, 188 countries or regions had reported cases of COVID-19. On 11 March 2020, the outbreak of COVID-19 was declared a pandemic by the World Health Organization (WHO). The relationship between human activity and the environment had been observed in various public health crises in the past, such as the Spanish flu and smallpox epidemics, and was observed again with the COVID-19 pandemic. Simultaneously, researchers predicted that a reduction in economic activity would target the issues created by global warming it would halt rising temperatures, as well as diminish air and marine pollution, and benefit the environment. ![]() Prior to the COVID-19 pandemic, measures that were expected to be recommended by health authorities in the case of a pandemic included quarantines and social distancing. Climate change has led to the melting of glaciers, an increase in extreme weather, loss of species, frequent wildfires, and rising sea levels. Increasing amounts of greenhouse gases since the beginning of the industrialization era has caused average global temperatures on the Earth to rise. Greenhouse gas emissions resulting from the treatment process of this plastic waste ranged from 14 to 33.5 tons of CO 2 per ton of mask, the largest share being from production and transport. Enforced public use of PPE has posed challenges to conventional waste management. During 2020, approximately 65 billion gloves and 129 billion face masks were used every month, and disposed of. ![]() The medical response required a larger than normal number of masks, gloves, needles, syringes, and medications. Production and use of medical equipment such as personal protective equipment contributed to plastic waste. The pandemic also led to increased medical waste. The hindrance of environmental policy efforts, combined with economic slowdown may have contributed to slowed investment in green energy technologies. However, decreased human activity during the pandemic diverted attention from ongoing activities such as accelerated deforestation of the Amazon rainforest and increased poaching in parts of Africa. One of these investments was the European Union's seven-year €1 trillion budget proposal and €750 billion recovery plan, " Next Generation EU", which seeks to reserve 25% of EU spending for climate-friendly expenditure. Some developed nations introduced so-called " green recovery" economic stimulus packages, aiming to boost economic growth while facilitating renewable energy transition. Greenhouse gas emissions rebounded later in the pandemic as many countries began lifting restrictions, with the direct impact of pandemic policies having a negligible long-term impact on climate change. In China, lockdowns and other measures resulted in a 26% decrease in coal consumption, and a 50% reduction in nitrogen oxide emissions. In April 2020, NO x emissions fell by up to 30%. In 2020, carbon dioxide emissions fell by 6.4% or 2.3 billion tonnes globally. ![]() With the onset of the pandemic, some positive effects on the environment as a result of human inactivity were observed. As public health measures were lifted later in the pandemic, its impact has sometimes been discussed in terms of effects on implementing renewable energy transition and climate change mitigation. ![]() As the pandemic became a global health crisis in early 2020, various national responses including lockdowns and travel restrictions caused substantial disruption to society, travel, energy usage and economic activity, sometimes referred to as the " anthropause". The COVID-19 pandemic has had an impact on the environment, with changes in human activity leading to temporary changes in air pollution, greenhouse gas emissions and water quality. ![]()
