Join the movement to stop childhood obesity

As you probably know, the number of obese and overweight children and teens have doubled and tripled, respectively, in the past 30 years.  For the first time ever, the lifespan of our children is expected to be shorter than ours.  Here's a website with lots of information and links to other sites for helpful ideas, stats, etc.  http://www.letsmove.org/   What do you think?  How can we help locally?
