Science is amazing. Imagine, we can now grow plants without soil. By doing so, we will use less space and very little water. This is called hydroponic gardening. We can also produce more nutritious plant products.
Hydroponic gardening can solve our problem of space. We are just too plentiful now. Our population growth rate is stressing Mother Nature. She is finding it very hard to cope. We can feed everybody on the planet using only a fraction of the farmlands we use today. Heck, we can even use barren land because we don’t need land at all. All we need is the space that the land gives us.
