I just watched a video from charity: water, in which Jennifer Connelly shows us the terrible plight of the hundreds of millions of people who live without access to clean water and sanitation. You can introduce this through a science/cultural activity.
Be Creative! And if you are, share it with the rest of us.
Then I took action with ONE and asked my senators to cosponsor the Senator Paul Simon Water for the World Act of 2009 (S.624), which will help bring first-time, sustainable access to clean water and sanitation to a hundred million of the world's poorest people. Check out the video and then make that commitment, too, by adding your voice.
Go here to make the commitment: http://www.one.org/us/waterfortheworld/index.html?rc=wftwtaf
Get parents involved with this as well and make sure your children are aware of the need.
