Shocking but the pandemic can save our world but at exceptional cost.  Is it the price we have to pay? Lock downs and supression result in a society that will curb the issues that lead to climate change.  

Latest is that a covid vaccination may not be developed and even if there is one the inequalities and the anti-vacs mean that many would remain unsafe and a threat to the rest so the risk would be prolonged with society adjusting to a more sustainable lifestyle.

A social deep-freeze strongly backed by government is ideal.  Unwittingly climate change is addressed at long last.  Enforced sustainability will reign.
