I don't think the pandemic and restrictions will save the planet if it needs to be saved at all. Perhaps if it comes to some countries.
Well, pandemic plan is to kill 75% of the people, depopulation,if they manage that in the next 5-10 years the world might look better in 100 years although it depends on what 'better' is according to Mother Nature.

All those face masks, disinfection, extra soup, washing, vaccines, syringes, needles and so on added a lot extra trash. Not forget to mantion the factories...
