I am in favor of deliberately spreading methodically prepared bacteria among people and animals -- mildew ... to destroy the harvests, anthrax to destroy horses and livestock, and the plague, in order to kill not only entire armies, but also the inhabitants of large regions.
It will not be humans who watch the sun's demise, six billion years from now. Any creatures that then exist will be as different from us as we are from bacteria or amoebae.
Natural selection certainly operates. It explains how bacteria will gain antibiotic resistance; it will explain how insects get insecticide resistance, but it doesn't explain how you get bacteria or insects in the first place.
When you're in the womb, you're in a sterile environment. When you enter the birth canal and the world, you're not. Very quickly, you have, living on the surface of your body, trillions of bacteria, literally trillion.
I would like to believe that the discovery of even a single fossil bacteria on Mars would teach us what we ought to know all along, and that is what binds us here on earth - all the diverse peoples here - is really much more profound than what seems to separate us.
If we recognise that every ecosystem can also be viewed as a food web, we can think of it as a circular, interlacing nexus of plant animal relationships (rather than a stratified pyramid with man at the apex)… Each species, be it a form of bacteria or deer, is knitted together in a network of interdependence, however indirect the links may be.
Science has eradicated smallpox, can immunise against most previously deadly viruses, can kill most previously deadly bacteria. Theology has done nothing but talk of pestilence as the wages of sin.
