People use plants more for food than for any other purpose?

I don't know that many who just use  it as food, others I know use them to make medicines, to keep specific arrangements in their landscape, and other times I've known them to keep their fish tanks clean (although, that is another subject).

Yep, that also some other things, but people usually uses plants for food, if they want to make profit, then they have to go with medicine plants as they are very high costed plants.
Small investment with low time high yields will come with Medicine plants, make sure to ask someone who can make you all things.
