The article is talking about the issues of growing potatoes. The way companies grow potatoes using chemicals and many bad components that are not healthy for the human consumption. To solve this problem they want to start using less chemicals, they want to grow them more naturally. Also this new way to grow potatoes would be less expensive compared to the one that uses many chemicals.
The image I have in mind is having a potato that was grown with fertilizes and chemicals next to a one that was grown locally with no chemicals. Also having the potatoes with some roots growing out of it. I think this would work because I don’t think potatoes that were grown with chemicals are able to grow roots like the one that are grown with out chemicals.
