You could argue that the coronavirus pandemic has given us a glimpse of what a greener version of the North West could look like: more people working from home and fewer polluting cars on the roads.
And the skies have been almost free from traffic, which has been more noticeable with the clear and sunny weather we've had in recent days.
And this is the kind of radical change needed, if we are to offset the climate crisis.
One of the possible solutions is an ambitious project at Smithills near Bolton.
It aims to plant millions of trees across the North to soak up Carbon Dioxide, one of the most important greenhouse gases.
