Environmental concern is a little like dieting or paying off credit-card debt - an episodically terrific idea that burns brightly and then seems to fade when we realize there's a reason we need to diet or pay down our debt. The reason is that it's really really hard and too many of us in too many spheres of life choose the easy over the hard.
My parents were kind of over protective people. Me and my sister had to play in the backyard all the time. They bought us bikes for Christmas but wouldn't let us ride in the street we had to ride in the backyard. Another Christmas my dad got me a basketball hoop and put it in the middle of the lawn! You can't dribble on grass.
