I don't think you can say that no one is suggesting those things aren't real issues. I think there definitely are other NGOs that deal with those issues. Most of those, particularly urban issues, are more local issues, and it's difficult for the federal government to get involved in urban sprawl, but I think the one tool that the government does have is to start putting a price on things we don't want.
If you don't want urban sprawl and you don't want these houses that are consuming huge amounts of energy, then putting a price on pollution or putting a price on carbon is one way to help discourage that. It's definitely one of the fiscal mechanisms at your disposal. Start allowing or encouraging people to make investments in other areas by making it unattractive to invest in things that pollute.
