What if the government heavily pushed the individual, organic garden? Building codes included greywater(non toilet water that is safe to put on plants as is) and composting toilet systems as nescessary? Outlawed(and enforced) the sale of non native plants, including grasses, for outside planting in every region, town and state? There was a bill passed that every house above a certain energy consumption/emission level(including trash) in say…20 years(to give technology time to catch up) would be fined and every house that complied each year before the deadline would receive major incentives and tax cuts forever?
