"With the absence of traffic on our roads, nitrogen dioxide levels (exhaust fumes) have dropped by more than 50% in some areas. across the UK.
You may have noticed the absence of contrails in the sky as fewer people are flying and with the recent fine weather it may seem the sky is bluer.
Less light pollution at night also makes the night sky appear clearer and full of stars.
People are noticing the bird song which may have been hidden before due to general noise and traffic. The birds have less to compete with now and the dawn chorus can go on way past dawn.
Townies are noticing more bees, birds, squirrels, foxes, even badgers, not just on walks but in gardens too.
Fewer bumble bees are dying by road kill and so more bee colonies are getting off to a good start, but some of the normal food supply for bees and pollinators has gone. Garden centres aren't open, so we aren't buying plants. We are also mowing our lawns, removing dandelions, weeds and wild flowers, which are natural bee forage.The same could be said for other birds and animals. The seagulls aren't as numerous in Newcastle because the food scraps from visitors have ceased and so they're relying on their fish'n'chip leftovers from elsewhere. They might even have to catch their own fish.
Is nature claiming back the city? Some seismologists say human activity has dropped to the lowest point since records began, so maybe it's just the humans that have gone quiet."
