...while these studies have sparked much talk about the Greenhouse Effect, the work of one Harvard biologist points to other adverse environmental effects--that the high carbon dioxide content is making plants less healthy and ultimately throwing the ecosystem off balance...
Timken Professor of Science Fakhri A. Bazzaz has studied the effects of carbon dioxide on plants and plant growth, and has found that more carbon causes plants to grow faster, but deprives them of adequate nutrients...
Until the 1800s, carbon dioxide levels in the atmosphere had remained relatively constant for the last 100,000 years, Bazzaz says...
...ever since the industrial revolution in the mid-1800s, carbon dioxide levels have been steadily rising. As industry expands, consumption of fossil fuels rises to meet the demands of that growth, he says...
Scientists have already found a direct correlation between the increase in fossil fuel use and the elevated carbon dioxide levels in the atmosphere. It is estimated that 80 percent of the carbon dioxide emitted into the atmosphere is due to industrial consumption of fossil fuels, while 20 percent is due to deforestation...
