Climate Change
FOSSIL fuels
~300 million years ago (before dinosaurs!):
Coal Oil
Now:
CO2
Burning Fossil Fuels puts EXTRA carbon
dioxide into the atmosphere
Carbon dioxide cycles naturally
CO2 CO2
Carbon from grass is converted to CO2 by herbivores and decomposers
Climate Change SOLUTION?• Bioenergy or Biofuels or Grassoline
CO2 CO2
When using grassoline as a fuel, CO2 that is produced would have been released into the atmosphere naturally through other processes
The BEST Experiment Question:Is Grassoline Sustainable?
OrHow green is grassoline?
BioEnergy SusTainability Experiment
• What kind of grassWhat kind of grass to make grassoline from?—lots of species (prairie) or just one species (switchgrass)?
• Should we fertilizefertilize to make the grass grow bigger? Will doing this create other kinds of pollution?
• What will happen to the ecosystemecosystem when we cut cut the grass (to make fuel)?
