Why more CO2 in atmosphere now than 500 years ago? burning of fossil fuels deforestation -- coal -- urban sprawl -- petroleum -- wildlife areas -- natural gas -- rain forests -- wood * The burning of ethanol won’t slow greenhouse effect. What can we do? 1. Reduce consumption of fossil fuels. At home: insulate home; run dishwasher full; avoid temp. extremes (A/C & furnace); wash clothes on “warm,” not “hot” On the road: bike instead of drive; carpool; energy-efficient vehicles 2. Support environmental organizations. 3. Rely on alternate energy sources. solar, wind energy, hydroelectric power
