A new study from Stanford's Woods Institute for the Environment has found that crop-based biofuels, in any form, is speeding up global warming rates by pumping far more carbon dioxide into the atmosphere, than conventional Fossil fuels.
The researchers looked at 20 years' worth (1980-2000) of satellite photos of tropical areas and discovered that half of the biofuel cropland had come from virgin rainforests.
- Speeds up rather than slow down global warming by fueling the destruction of rainforests
- Imbalance of deforestation leading to eco-unbalance
- Takes 40 to 120 years to pay back the "carbon debt"
- Impact on food prices and the amount of energy it takes to produce them
"If we run our cars on biofuels produced in the tropics, chances will be good that we are effectively burning rainforests in our gas tanks"
