This video led me to an interesting website that has great links on how to help your family and friends reduce your environmental impact.
The learning idea I took away from this site is a good example of to incorporate good resources from other websites into your training. Of course, you'll need to check the links on a regular basis - the Internet is an ever changing tool - but you can take advantage of really great information at a low cost.
