[Interstellar] Why couldn’t they just build green houses on earth?

In the movie it seems like the main reason they need to escape earth are those storms that destroy crops. But the storms don’t seem like they take out buildings, what’s stopping humanity from just building a series of greenhouses to get our food that way?

The storms are the symptom, not the disease. The blight is what's killing everything. Small greenhouses would work, but you would need absolutely massive greenhouses with advanced sterilization procedures to grow food for the entire world.
