What We Will Do next Sunday (and the rest of the year)
- turn off electrical equipment and kill the "sleep" modus on a number of appliances
- share rides (amazingly, this morning again, the proportion of the vehicles that I've spotted in my usual traffic jams that had a sole occupant was +85%)
- buy a new bike soon for every member of the family
- eat more "local" food
- recycle more
