This entry comes by popular request. A lot of people have been asking what they can do to use less oil, and reduce demand for the sticky stuff ruining beaches everywhere. Here's my top ten, feel free to add to it in comments:

1. Carpool, cycle or use public transport to go to work.

2. Choose, when possible, products packaged without plastic and recycle or re-use containers.

3. Buy organic fruits and vegetables (fertilisers and pesticides are based on oil more often than not).

4. Buy beauty products (shampoo, soap, make-up) based on natural ingredients, not oil.

5. Choose when possible locally produced, seasonal products (less transport involved).

6. Buy clothes made out of organic cotton or hemp - not from oil derivatives.

7. Use non-disposable items in picnics and summer festivals.

8. Quit bottled water.

9. Fly less.

10. Demand that your government encourage renewable energy instead of subsidizing oil.
