Sponsor Child's Fate

I decided to sign up with World Vision and sponsor a child. I am sending my money to a beautiful 4 year-old little boy and his mother. The money will enable them to receive an education and be able to create a lifestyle that benefits not only them, but others in their community. I am extremely proud to be supporting this young child and his mother. The only problem is that they live in Cape Town close to the ocean in South Africa. I realized after watching "An Inconvenient Truth" that if Antarctica does melt and the sea level does rise my foster child will have more problems than he does presently. He could possibly even die. Something needs to be done to save this precious child.
