What I do for the environment

Since I recently posted about what I see that harms the environment, I thought I'd list off some of the things I do to help the environment. Most of these are very easy to do.

1. Recycle - For me, this is ingrained. Growing up, my family always recycled. We had so many garbage cans that guests were often very confused - recycling, regular, burnables (okay, this may not be as environmentally friendly), and a bucket for veggie and fruit scraps. If curbside pickup is available, I can't imagine why someone wouldn't recycle. It's so easy!
2. Reusable bags - I've already posted about this. I have tons of bags and use them as often as I can remember to do so.
3. Walk (or bike) to work (and to the store) - Admittedly, I only do this when the weather is nice, but I have been walking to work as much as possible. Of course, walking to work is only an option for those who live relatively close - in my case, a little over a mile.
4. Carpool - In the winter or in bad weather, I carpool with my boyfriend. I'm not sure it's a huge savings, because there is a shorter route he could take to work. I think it's better than taking two cars though.
5. Reuse - My sugar jar is a former spaghetti sauce jar. We mix our own balsamic vinaigrette and our current jar used to be a jelly jar. Most of my furniture is second- (or third- or forth-) hand. I am a scrap paper fiend, even collecting it from the unclaimed printouts at work. Reusing is easy - and cheap!
6. Compost - I have just begun composting and will write more about this in a future post.
7. Grow your own vegetables - Another topic on which I have already posted.
8. CFLs - When bulbs burns out, we switch them to compact fluorescent light bulbs (CFLs).
9. Thermostat - To reduce our energy use, we set the thermostat to 67 in the winter (which is difficult for a freeze baby like me) and 80 in the summer. I'd love a programmable thermostat but we are in an apartment.
10. Reusable Water Bottles - I have very rarely bought bottled water. It just seems like such a waste and completely unnecessary. Tap water is monitored. I carry around a reusable water bottle, which is especially handy at work.

If you have any suggestions of things you do, let me know! I am always looking for more things that I should be doing, particularly if they are cheap and easy. :)
