This is a good analysis, if a little negative, given what I hoped you would know. I was tempted to go again through the detailed systems analysis description of how all plants live through their early years extracting energy, from Earth only to live much longer, growing much bigger, contributing energy to Earth fom the sun after their leaves have formed, and our leaves, as a species are only beginning to form now, we have about 10% of what is needed. But, you probably read it at least once previously, I guess you have your own reasons for writing as if you didn't know about it, or maybe don't accept it :)
