Poverty, climate change, militarized U.S. mentality and economy, growing numbers of stealth terrorists, job shortage, dumb-down public policies,  involved service shortage, etc... the list of needs that a ROBUST American World Service Corps national service program could address is long.
We need to start addressing these needs today in a BIG way so that movies like Zero Dark 30, Day After Tomorrow, and Hunger Games don't become reality tomorrow.
