What do you do for the environment?

Yosi wrote a post after watching "An inconvenient truth" (shown again in Israel this month), telling how he was affected from the movie.
What I did for the environment:

1. Replaced most light bulbs in the house (mostly those without dimmers) with economic light bulbs (which consume 20% power compared to a normal light bulb)
2. I try to recycle waste (a big problem in Israel)
3. As a fan of light drinks I recently got a home soda maker, making me consume soda without consuming plastic bottles.
4. I try to each less meat
5. I tried to avoid buying imported food (which consumes more energy due to transportation)

Here is another short movie explaining the environmental issue:


I also recommend watching the documentary "Crude Impact - Peak Oil Documentary".
