Investors and entrepreneurs behind some of the world's newest industries have started to put their money and tech talents into farming -- the world's oldest industry -- with an audacious and ambitious agenda: to make sure there is enough food for the 10 billion people expected to inhabit the planet by 2100, do it without destroying the planet and make a pretty penny along the way.
Silicon Valley is pushing its way into every stage of the food-growing process, from tech tycoons buying up farmland to startups selling robots that work the fields to hackathons dedicated to building the next farming app.
"The food sector is wasteful and inefficient," said Ali Partovi, a Bay Area investor with large stakes in sustainable agriculture startups. "Silicon Valley has a hubris that says, 'That's stupid. Let's change it.'"
