A project that I’ve had a small contribution to is the Guardian's Live Better Challenge. The site present a monthly challenge to readers which would make a great focus for a school eco-club or similar. This month’s challenge is to reduce your domestic energy use by 10%. There are plenty of resources and teacher aids on the site, including some resources that I contributed to. The site is going to run for seven months and there are plenty of useful and interesting articles such as this one that asks if there is too much modern technology in our lives.
