Marshalling convincing scientific data, they tell us that the environmental degradation caused by massive pollution of air water and land, threatens the very life of earth — fast depletion of non renewal resources, indeed of species themselves, the thinning of the ozone layer that exposes all living creatures to the danger of radiation, the build up of gases creating the greenhouse effect, increasing erosion by the sea — all these are brought out through their research.

Recent increases in an unregulated ozone - depleting substance, could delay recovery of Antarctic ozone levels by 5 - 30 years, depending on emissions scenarios.

In 2004, Looy and her former Ph.D. advisor Henk Visscher proposed one way this might have played out, bases on fossilized abnormal plant spores found worldwide: volcanic gases — halocarbons like methyl chloride and methyl bromide — destroyed much or all of Earth's ozone layer, boosting UV - B exposure that would have affected life and potentially increased the genetic mutation rates in pollen and spores of plants worldwide.

The observed contrast, however, is just that expected from the combination of greenhouse gas increases and stratospheric ozone decreases.

But the reactive gases emitted by trees can also increase the amounts of ozone and methane, both greenhouse gases which have warming effects on the climate.
