Small Is Beautiful
Energy is neither created nor destroyed. Recalling Einstein’s famous formula a small mass of matter when converted releases tremendous amount of energy. All that energy mankind has ever possessed or shall, owe to what was released at the time of the Big Bang.
Evolution in a manner of speaking is a transaction of so many species with energy as a bill of exchange. Naturalists reckon land animals under the existing conditions, could hold a weight of 100 tons but no animal has come anywhere near that mark. ‘Small is beautiful’ is the message the size of animals seems to indicate. Trimmer they are, less energy they shall need to expend we might say.
