I was talking to my wife Liz’s “Mum,” Dawn, who is here from New Zealand for a visit. Back home, Dawn and her husband Stuart, house share with one of their daughter’s families. Our platform calls for a considerable amount of house sharing, I told the LaCross Tribune in Wisconsin during one of our recent tours. It only makes sense, common sense. That is, if we want to reverse global warming (and the environmental cancer of urban sprawl), we should double up in homes to share heated space, to share lighted rooms, to share furniture and appliances (which all take fossil fuels to make). What’s more, we would halve expenses, freeing up all kinds of money for carbon offset projects, humanitarian aid programs to the Third World, etc. The only thing keeping most of us from doing this in America is: our selfishness around space and our fear of intimacy and community building with others. Granted, these can be big things. However: GET OVER IT AMERICA — so our children will have a world to grow up in!
