There's some girl on my Facebook who brags about buying a new car every year or so.

I don't want to seem like a jerk so I haven't said anything but I want to ask her how she feels about the world she is creating for her son to grow up in. All the pollution created from the fuel consumption; the environmental refuse from the tires, parts, metal, etc; and the waste of money on the cars, maintenance, gas, taxes for the roads.

I'd probably go on such a rant I'd end up making her cry or something and I'd feel bad.
