America had a taste of what a growing number of nations face: food rationing.

Last week, Sam’s Club and Costco restricted the amount of bulk imported rice consumers can buy.

There have been food riots leading to deaths in Cameroon and the removal of the Haitian prime minister.

Josette Sheeran, executive director of the World Food Program, called the rising food prices a “silent tsunami” that is going to push millions of people into poverty.

Rice accounts for one-fifth of the calories humans consume. It is a staple in many diets worldwide.

Action needs to happen now. Global warming is affecting crops.

Countries around the world are giving more land over to growing crops for biofuel and food for cattle—land that was used to grow food for people.

Forget biofuel. It’s time to focus on innovations like electric-powered cars to get the world over the fossil fuel dependence.

This is a global problem that requires a global solution. If action is not taken, expect the situation to worsen.

Maybe we’ll even have our own food riots in the poorer areas around the country.
