Yes, I know of that method. Also, there are many water recycling methods available. In addition, there is this certain kind of soil, I can’t remember the name of it, that you build with things available fairly easily and once it is built, you never need to fertilize—it’s living soil. I’ll look around my bookmarks and see if I can find that info. Anyway, imagine if in our own cities we used abandoned buildings to grow multilevel produce, using this type of soil, recycled water, computer and robotic technology to keep everything on track...cities could literally feed themselves and plenty of jobs would be available. It’s really a crying shame we’ve let progressive politics tear down this great country. Just imagine what we could do for ourselves and the world at large if we were unshackled from gov’t. I’d love to see this kind of stuff happen somewhere in the world. Makes me want to cry when I think of all the initiative we waste in this country.
It took me a bit, but here’s some info on the soil I mentioned previously. It is called Terra Preta. Although I could not find the original places I gathered info. from in the past, I found a variety of links that explain it in varying degrees. Environmentalist of all ilks are very interested in Terra Preta, so if you are not of that mind-set, please over look all the save-the-planet references. I don’t consider myself an environmentalist, but rather just a good caretaker of the beautiful place God gave us to live in. I apologize if this is redundant info. for you.
