In a three-part series, Tom Peeters explores how to feed all those people. Innovation promises solutions. Vertical farms, including Europe's largest in Denmark, seek the heights. In Finland, scientists are growing coffee in bioreactors and even extracting food "from the air." That kind of farming in the lab has the potential to fundamentally change the way we have farmed for millennia. But don't these powerful samples of technology seek to take it too far? For example, could food forests be a valid alternative to industrial mega-farms?
