I would like to point out that that day I get married and sign away half of my possessions to someone I'll eventually get sick of is the day I've lost it. Marriage is NOT the genetic drive of the male... sex is. We are wired to plant our seed with as many women as humanly possible. Several thousands of years of evolution have put this drive into us. The "social engineering" of the past 300 or so years cannot override that. So if by "something wrong" you mean they are smarter than the average stupid drone and choose not to fall into that trap then yes, their is really something wrong with them. The divorce rate is sky high.... cheating on your spouse is so common that it's almost expected in some circles. All of this points to the fact that marriage is an unnatural act.
Getting back on topic.....
The thing about being green is i's more of a way of thinking than an actual act. When I do things from day to day I am conscious of the energy I'm using and try as much as possible not ot be wasteful. When I purchase a new car, new light bulbs or anything of that nature I think the same thing and that mindset effects my decisions. On the other hand, there's conservation and then there is what I like to call "being a crazy hippie." I buy primarily florescent bulbs because they are reasonably priced and they reduce my energy consumption. I do NOT buy hybrid cars because they are some made up b.s. by the auto/oil industry designed to distract you to the fact that sticking a redundant gas engine in an electric car negates any cost/energy benefit due to the extra wieght. I don't have a bank of solar panels on my roof because they don't work well yet and they are very expensive. When they get better I will though. I walk to near by places. The walking is good for me and I don't mind, but if it's far enough away to where I do mind, ---my bottom--- is taking the car. I don't buy hummers, pickup trucks or suvs, because they are a ridiculously inefficeint form of transportation unless you actually need to haul around 10 kids, or a piece of plywood every day. On the other hand, you won't see me in a ford focus either because I like to drive without my knees hitting my stomache.
Long story short, there isn't a whole lot you can do right now, but it is important that you do what you can. it is also important that you pester your local politicans to do more because unfortunately, things like global warming aren't going to be solved by the indivdual alone as industry pollutes more than you could if you tried.
