    To deal with a changing world, we have to change as well. Transforming land into farms removes forests and worsens climate change. But we need to grow more food to support a growing global population. What can we do?

Scientists have discovered that plants grow best under a certain type of light, which can be provided by red and blue LEDs. The combination of these lights at the right level makes a space look pink. Since “pinkhouses” supply their own light, they don’t need to have fragile glass walls and ceilings. And they can be set up anywhere, including places that don’t get the amount of light greenhouses need.

Since pinkhouses can pack food in huge columns, one of these farms doesn’t need a lot of land. Farmers can set up pinkhouses in cities. They completely control temperature and light, which can help some plants grow twice as well in pinkhouses as they do in traditional farming. Pinkhouses can allow for many more harvests per year since farming doesn’t have to stop in the winter.

Even though pinkhouses are a great way to grow crops, lighting and heating an indoor space is very expensive. It doesn’t make sense to grow foods that take up a lot of space or that we need to grow lots of, like wheat, rice, and corn, in a pinkhouse. We will still need to grow those crops in fields. We can start farming smarter.

Farmers will use satellite imagery to figure out exactly where to plant each crop. Think of a mixture of just the fight crops, rather than a rectangle of one type of plant. Sensors in the fields will measure the soil’s water level：temperature, and chemical content. They will even be able to detect insects and send out notifications to a smartphone app. Irrigation systems will be tied to weather forecasting programs, allowing very precise watering and care, all calculated to get the best plant growth and yield.
