My family only has 4 people. I have a sister (who is 18) , my mom and dad, and of course me. Yet despite having only four people in our family, we have two cars. I don't think that's very environmentally-friendly. Plus, my family produces a lot of plastic and paper waste.
I don't think my family's life style is possible to maintain in a post-oil world. Do you have any suggestions on how my family can live in a post-oil world?
