The world’s population is set to skyrocket to 9.7 billion by 2015. That’s 2.5 billion more mouths to feed, which will not be possible if we keep growing food the way we do, especially with the threat that climate change poses. That’s why there’s never been a more important time for “vertical farming” to be implemented on a large-scaled. Vertical farming is sustainable and allows for controlled growing conditions, translating into consistent yields. More vertical farms also means we can pay farmers to plant carbon-sucking trees instead of corn as a way to sequester the greenhouse gas. Vertical farming can be the solution, as long as we start implementing it now.
