In many high income countries people now eat more meat and more foods that are grown abroad. Why does this threaten food security in other parts of the world?
The crops grown in low income countries become less able to resist new pests
The birth rate in low income countries rises as more food is exported to them
Farmers in low income countries are made to use much larger volumes of water
Scarce food resources are transported away from the countries that grow them
