Interesting read from the New York Times on vertical farming.
If climate change and population growth progress at their current pace, in roughly 50 years farming as we know it will no longer exist. This means that the majority of people could soon be without enough food or water. But there is a solution that is surprisingly within reach: Move most farming into cities, and grow crops in tall, specially constructed buildings. It’s called vertical farming.
The graphic alone is interesting (below), but take a minute to read the full op-ed.
