Saving Trees and Ozone
How does saving trees effect the ozone layer?
Could I please get the answer as soon as possible?
There are two different types of ozone in your question:
One is bad ozone:
Trees help lower ozone and pollutant levels in cities:
The other is the good ozone layer (15-40 km above the earth's surface) that
protects life on earth from harmful UV radiation:
but trees don't have any big direct impact on this, although oxygen
produced by early algae/phytoplankton probably initially helped create it
millions of years ago.
