摘要

And for the quarter of the global population now living under a coronavirus lockdown, a lack of cars and planes has made the world quieter and birdsong more apparent. While there are signs of easing pressure on the environment, no credible environmentalists say the response forced by the pandemic is a solution for the challenges the world faces on climate change, pollution and biodiversity loss.
