The drastic improvements in air and water quality due to the coronavirus lockdowns have led to calls for a low-carbon future. However, the pressing need to re-employ millions of people is complicating the environmental situation. As economies shut down worldwide, wildlife has returned to urban areas, with various animals being spotted on typically busy streets. Fish have been observed in clean Venice canals, and some Indian residents have seen the Himalayas for the first time in years. Satellite images show significant improvements in air quality in Europe and Asia, including China, where the pandemic originated. Despite this progress, residents in heavily polluted Chinese cities are concerned that pollution levels will rise again as the economy reopens. Tang Zhiwei, a 27-year-old resident of Shanghai, stated that as the epidemic eases in the second half of the year and factories reopen, the weather will gradually worsen. He advised people to make the most of the blue sky while they still can. Thunberg emphasized that taking action against the coronavirus does not mean that the climate crisis has disappeared. She stressed that on Earth Day, it is important to address both the coronavirus pandemic and the ongoing climate and environmental emergency simultaneously. UN chief Antonio Guterres urged governments to use their economic responses to the pandemic to also address the deeper emergency of climate change. There is a global divide between investors supporting environmentally friendly economic stimulus measures and industry lobbyists trying to relax climate regulations, according to Guterres. He warned governments against rescuing heavily polluting industries and emphasized the urgent need to address the planet's environmental crisis. Peter Betts, a former climate negotiator, stated that there is now a push for economic stimulus packages in response to the coronavirus to prioritize low-carbon solutions. However, there is concern that some governments may prioritize economic recovery over environmental concerns. US President Donald Trump's priority is to revive America's oil and gas industry and ensure that important companies and jobs are secured for the future. Climate change is a growing concern, with last year being the hottest on record in Europe due to high levels of greenhouse gases in the atmosphere. C3S director Carlo Buontempo stated that the warming trend is now evident worldwide, leading to an increase in the frequency of record-breaking events. The head of the World Meteorological Organization (WMO) mentioned that the coronavirus pandemic is expected to cause a 6% decrease in carbon dioxide emissions this year, the largest drop since World War Two. However, the WMO emphasized that this reduction will not halt climate change and stated that COVID-19 should not be seen as a replacement for ongoing climate action. With many people staying at home, there has been an improvement in air quality in China. Emissions in Shanghai decreased by almost 20% in the initial three months, and in Wuhan, where the outbreak began, monthly averages dropped by over a third. However, experts are concerned that this decrease may allow China to overlook pollution in an effort to boost the economy, which experienced its first decline in the first quarter.
