So, just for fun, let's try to predict the past with the benefit of hindsight.
In that case we would have to listened to the 'brilliant scientists' and cut down all the trees on earth because they produce methane gas.
In 1907, Francis W. Bushong, a chemistry professor at the University of Kansas, reported a novel finding in the journal Chemical and Physical Papers.
He'd found methane, the main ingredient in natural gas, in a tree.
Years earlier, he wrote, he'd cut down some cottonwood trees and "observed the formation of bubbles in the sap upon the freshly cut trunk, stump and chips."
When he struck a match, the gas ignited in a blue flame.
At the university, he replicated the flame test on a campus cottonwood and this time captured gas samples.
The concentration of methane was not much below the level measured in samples from Kansas's natural gas fields.
Conclusion we must cut down all the trees on earth and use the wood to make butt plugs for cows and people who eat beans.
