The amount of sulfur dioxide in the air of London reached its peak around 1850, by 1950 it was one tenth that, today it is one tenth that again. The number of particles in the air reached its peak in 1960, today it is one tenth what it was. Carbon monoxide has been reduced 80% since 1990 and there was a similar reduction in lead compounds; the reduction of nitric oxide has been less dramatic but even here has been cut in half since 1975. Yes the amount of carbon dioxide has increased but that's not necessarily a bad thing. Experiments have shown that the amount of plant biomass increases with approximately the square root of the carbon dioxide abundance in the air, so the 30% increase in CO2 over the last 60 years resulted in a 15% increase in food production and a 15% increase in planet Earth's total biomass. Also, an increase in CO2 makes plants more drought resistant. John K Clark -- You received this message because you are subscribed to the Google Groups "Everything List" group.
