For those who have children these short videos brought to you by PBS are awesome for inspiring kids to be more environmentally responsible.
I know this is not design, but I think it is all related. If we teach our kids that we don't need stuff to make us happy, to recycle and to reuse, then that is a wonderful step for the future of design. As I have said before we don't have to sacrifice the environment for good design...the two can work together for a healthy and happy future!
To get your kids started maybe get them a re-usable water bottle. Here's a BPA free one by Klean Kanteen that comes in a myriad of colors...
Hope your kids like the videos as much as mine did!!
