Some people hope that machines like this automated spinach harvester will help farmers deal will less immigrant labor.
The Salinas Valley in Northern California grows about 80 percent of the country's lettuce, and it takes a lot of people to pick and pack it. In a field owned by Duda Farm Fresh Foods, a dozen lechugueros, or lettuce pickers, are bent at the waist, cutting heads of iceberg lettuce. They work frantically to stay in front of a line of 12 more packers, who seal them with tape and toss them onto a conveyor belt.

Tenth Street Elementary is in the Pico-Union district of Los Angeles, a few blocks west of the Staples Center and downtown skyscrapers. It's a tough neighborhood; school security is always an issue.
On a recent day, about 150 third-graders were spread across a worn cement playground, running around, playing chase and tag.

Owens Valley and the Sierra Nevada, the high desert environment that is drier today because of a century worth of water diversions to Los Angeles, some 200 miles away.
It's been almost 100 years since William Mulholland stood atop an aqueduct along the Owens River and said, "There it is, take it." He was referring to a diversion channel that started piping water to Los Angeles from 200 miles away. That water allowed L.A. to become the metropolis it is today.
But it also meant that the Owens River no longer flowed into the massive Owens Lake, which quickly dried up and became one of the biggest environmental disasters in the nation.
Hikers walk on the Mist Trail to Vernal Fall at Yosemite National Park in California. The National Park Service has to cut $134 million from sites around the country, including Yosemite, due to the lack of a budget deal in Congress.
Spring has come early to the Yosemite Valley, and the melting snow makes for a spectacular rush of water off the granite face of Yosemite Falls, the tallest in North America.
Early March is when park officials would normally be gearing up for the busy tourist season. Instead, they're figuring out how to cut $1.5 million from their budget. Without a budget deal, the sequestration has forced the Park Service to cut a total of $134 million from sites around the country.
