Five Quick Green Ideas

After reading about Home Depot's efforts at greening their inventory, I was thinking about the things I do everyday in order to make less of an environmental impact. And I'm going to pass on the five easiest things to you, as a challenge to you, but also, I'd love you to leave your own challenges in the comments section.

1. Reusable coffee stirrer: I quit using the plastic and wood stirrers from the cafeteria and now I use a glass swizzle stick that I got at Crate and Barrel. Bonus: It has a cute goldfish on it.
2. Handkerchiefs: Easier to carry around than a pack of tissues, and reusable too. Also stylish and debonair.
3. Sigg Water Bottles: Instead of picking up a new plastic Poland Spring bottle when you're thirsty, try refilling a Sigg. I got mine at EMS and it beats a Nalgene, hands down. No flavor retention, insulated metal for keeping drinks chilly, and handily clips to your bag.
4. Use your feet: It's summer, so get outside and walk where you're going! I've taken to doing as many errands as possible by foot/subway to reduce the use of the car. Bonus: It's exercise. Bonus bonus: Save on gas.
5. Bring your lunch to work: Instead of splurging on fast food that creates waste packaging, bring leftovers or a homemade sandwich in Tupperware, or, my favorite, glass Pyrex dishes. Bonus: Less grease.
