I can never fathom how it is a benefit to "invent" a way to use fertile ground (they aren't making it anymore) to increase greenhouse gases, no matter how you size it up or imagine a benefit.
Clean, non toxic, inexpensive food is one of the few things that makes sense to produce with the soil. Of course there are distribution problems galore to solve real problems.
When are we going to stop inventing things that will make us more hated. Using the earth's very limited resources to move four thousand pound vehicles with all the creature comforts reminds me of the joke:
There won't be problems with global warming because we have air conditioning.
This is a short sighted (probably profitable), extremely misquided effort. What about conservation, extreme conservation? Someone please tell me how I am wrong?
