plant, grow, and harvest food autonomously, can use as little as 1% of the land that a conventional farm would use to grow the same amount of food. The systems are still at a relatively early stage and expensive, but beginning to prove that they can be profitable. Right now, vertical farm companies focus on leafy greens, which make the most sense financially, but berries and vine crops will soon follow. Other indoor agriculture facilities, like a large, state-of-the-art greenhouse now growing tomatoes in Appalachia, use one-thirtieth of the land used in traditional farming. A new vertical wheat farm grows as much in 850 square feet as could normally grow on 30 to 50 acres. … [Read more...] about Why we need to “rewild” our environment
El nino and climate change
Until recently, a remote corner of the Big Island of Hawaii was barren. The area was originally an ancient sandalwood forest, but hundreds of years ago, when the trees were cut down to sell the wood and cattle started grazing on the land, it became what is now essentially desert. Today, a startup is piloting a new system to bring the forest back on a 45-acre plot—and to demonstrate an approach to reforest the planet quickly enough to fight climate change. … [Read more...] about Reddit’s former CEO is now in the forest-planting business

Webb, a native Kentuckian who graduated from college around the time of the 2008 financial crisis, has spent his life watching the coal industry collapse. But he recognized that the region has more possibilities that just mining. The state’s location is strategic for deliveries: Trucks leaving the area can reach 70% of the American population within a day. (Amazon is building a new hub in Kentucky for the same reason.) With year-round, efficient production, a food company could compete with produce coming from much farther away. “Instead of shipping five days on an 18-wheeler from Mexico or California to the eastern part of the U.S., we can get that down to a one-day drive,” Webb says. He calculates that would mean using 80% less diesel than trucking produce from Mexico. … [Read more...] about This startup is going to put one of the world’s largest sustainable greenhouses in coal country
