creative project question?

Question

i need help on ideas. Im suppose to combine two things and start a movement with it that can help solve an issue. For example, cooking plus gardening can relieve stress. Can you guys and gals please help me??

Answer 1

If you raise fish (trout are easy enough) and vegetables (tomatoes) in a closed system using the fish water to fertilize the veggies and using the veggies to filter the water you can grow both and conserve water at the same time. You then have two cash crops and use a minimum of water.
