    We must also protect our global environment, working to ban the worst toxic chemicals and to reduce the greenhouse gases that challenge our health even as they change our climate.
    Now, we all know that in all of our communities, some of our children simply don't have what they need to grow and learn in their own homes, or schools or neighborhoods. And that means the rest of us must do more, for they are our children, too. That's why President Bush, General Colin Powell, former Housing Secretary Henry Cisneros will join the Vice President and me to lead the President's Summit of Service in Philadelphia in April.
    Our national service program, American Corps, has already helped 70,000 young people to work their way through college as they serve to America. Now we intend to mobilize millions of Americans to serve in thousands of ways. Citizen service is an American responsibility which all Americans should embrace, and I ask your support for that endeavor.
