I agree with the person who said "All houses in someways are negative externalities because of the trash that is thrown away into landfills." I think this is true because no matter how hard people try to do good things and produce positive externalities there are all these little things that can build up and produce major negative ones. My family doesn't recycle and that is a huge negative externality. Right now I can't honestly think of too many positive things that my family does. -Amanda
