Ecological footprints

During our class period we learned about ecological footprints. What we learned about ecological footprints was very interesting. In class we had one of our classmates volunteer and we calculated his ecological footprint. If the world as a whole had the same ecological footprint as we in America that there would not be enough earth to sustain all the people living. The scary thing is that India and China are growing really fast and want to be as advanced as us in America. If China and India's ecological footprint gets as high as the average American there will be a huge problem for the world. One way or another we as Americans need to start depleting our ecological footprint.
