How will food be produced in the future?

In my topic I want to talk about how our food will be produced. The article talks about how our food will be grown with more scientific methods because we are producing a low amount of food. Our food has really become less and less real food as the years go by. Although it still is food most of it is made with chemicals and has food supplements in it. They have been using chemicals to try to mass produce our products even though they cause harm once in a while. At the moment farmers still grow their crops, but what if in the future our food is grown by machines? What if all it takes is a click of a button? Maybe using robots will make it so that the crops are planted faster, but what if those machines don't take care of the crops the proper way and they crops die and you have to wait a couple of more months so that you can finally get your food.
