In nature, one can expect many parallels. Many animals have four feet. There are apes, lions, camels, and tortoises. Are all these related? Not really. Again, nearly all animals have two eyes in their head. Is there significance beyond the fact that this enables stereoscopic vision along an excellent line-of-sight? And so we come to the two substances most closely associated with life processes: the chlorophyll of plant life and the hemoglobin of animal life. Chlorophyll produces the food plants need for survival. Hemoglobin carries nutrients and oxygen essential to animal life. Although animals and plants are different, there are interesting parallels to be seen in…

One day they discussed with me their new found interest in aquaponics.1 I received a royal tour of the greenhouse, which holds a basin for fish, pumps, tubs, tubing, gravel beds, and filters. I was favorably impressed! One Man's Poison Fish produce body wastes. The word wastes in this instance can be changed to treasure, as the fish wastes serve as food for the plants. The waste water is pumped through plastic piping above tubs of pea gravel, in which the plants are rooted, free of soil. The piping has small holes. This sprinkles…
