California is experiencing the worst drought since records began being kept more than 100 years ago. It's been going on for about four years now.
The state is so dry the governor recently put water usage restrictions in place.
What happens if the state runs out of water? The entire nation is affected, according to a report from the Discovery Channel's DNews.
Some reports say California has only about a year of water left in its reservoirs. If the drought continues, the U.S. will see strain on the production of its fruits, nuts and vegetables — it produces 70 percent of America's greens.
How much water does it take to grow some of our favorite foods? According to the EPA, it could take 1,800 gallons of water to raise a single pound of beef. Watch the video for more of the DNews report.
