1) We recycle like crazy.
2) We have a trash compactor that vastly reduces our volume to landfill.
3) We never water our "lawn".
4) We use a number of CFLs.
5) Prius @ 50 mpg, 1997 Accord @ 30 mpg, we carpool when we can.
6) Probably the biggest thing...we teach our daughter about respecting the environment.
OTOH,
1) I travel for work on airplanes at least 10 times/year.
2) We travel by airplane for vacation probably 4x/year.
If they could just get those electric airplanes to work!!
