I don't always do the little things. Don't always recycle, drive a big truck, live in a bigger house and heat a bigger shop than I need, waste things, etc.
My environmental improvements have been much bigger picture things. We purchased a 100 acre farm in 1990 that was all bare row crops and totally converted it into wildlife habitat; built two ponds, planted 40,000+ trees, planted 50+ acres of native prairie grass, maintain 20 acres of wildlife food plots, selective timber stand improvements, etc. Have since purchased another 150 acres in various parcels and now doing similar things with this ground.
