摘要：With the first known case of Covid-19 reported in China on 31 December 2019, 2020 has witnessed the single-biggest disruption to the global tourism industry since records began, with devastating economic impacts. An unexpected outcome of the pandemic, however, has been a range of benefits for the natural environment. For example, the canals of Venice have begun to run clear and some depressed coastal fish-stocks are making tentative steps towards recovery, as both fishing and supply chains have been disrupted (Bennett et al., 2020; Braga et al., 2020). More extraordinary still, the world has reduced CO2 emissions to where they were a decade ago.
