Low hanging fruit

One of the things I am trying to do this year is become more environmentally friendly. I used to be much more granola crunchy than I am now, and miss that part of me. I'm trying to start easily and make simple changes first. Here's what I've done so far:

• Got a reusable lunch bag and sandwich wrap for my office lunches. I have a stack of cloth napkins that I use as well that just get tossed in the laundry.
• Set up a recycling station in the back entry to collect recyclables.
• Purchased cloth shopping bags.
• Started using stainless steel water bottles rather than plastic.
• Buying organic and local produce at the grocery store.

What are some other easy suggestions to re-green my life? I figure I'll pick off the low hanging fruit first, and then work my way up from there.
