Man(kind) often thinks he is smarter than nature, but he is wrong.  Modern agriculture is a prime example.  If you look at farm fields that have been worked for decades, you’ll see dry, cracked dirt. That hardly looks like the healthy, nutrient-dense soil we find in the forests that Mother Nature takes care of. Tilling actually kills the soil biome and releases carbon into the atmosphere.  And as the soil biome steadily dies, more and more artificial fertilizers are needed.  Furthermore, plants don't like to grow as single monocrops in straight rows.  A lack of plant biodiversity attracts pests which require insecticides (deadly chemicals) sprayed onto the crops. While these genetically modified plants might be immune to the poisons that are sprayed on them, we certainly are not!

In nature, the soil is covered and there is biodiversity. You can observe companion plants growing near one another which can naturally repel each other's pests and improves the soil by increasing nitrogen and/or dynamically accumulating nutrients deep in the soil so that plants with shallower root systems can benefit from.  If we simply plant plants where they want to be, next to plants they want to be by, they will flourish and provide abundance. Healthy Soil = Healthy Plants.
