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.
I always think about which blood drive was going on in Georgia that day when that husband or mom or school teacher rolled up their sleeve and actually gave me a second chance at life. It's the ultimate gift of life and I'm the one who was on the other end.
