Aren’t plants literally making food out of thin air? They take a series of photons and pull the carbon out of the “thin air” to make food.

  Yes, but inefficiently. The idea is to do the same thing with much less land area, so we can stop using 40% of the planet's land to feed ourselves.

  Yes- it's carbon fixation.
