To feed its 1.2 billion people, China may soon have to import so much grain that this action could trigger unprecedented rises in world food prices. InIn an integrated world economy, Chinas rising food prices will become the worlds rising food prices. Chinas land scarcity will become everyones land scarcity. And water scarcity in China will affect the entire world. Chinas dependence on massive imports, like the collapse of the worlds fisheries, will be a wake-up call that we are colliding with the earths capacity to feed us. It could well lead us to redefine national security away from military preparedness and toward maintaining adequate food supplies.
