That the world runs on recycled poo is hardly a revelation - after all, the vast majority of life on earth is entirely dependent on the plant and bacterial poo we call oxygen being recycled back into the atmosphere - most everything we consume has been the poo of another creature at some point. But I thought the whale poo thing and the cow poo thing were kind of interesting in the details. I don't really know too much about it, but I'm guessing the whale-krill-phytoplankton food chain might be one of the simplest such systems in existence and in that respect its an interesting one to study. More whales = more whale poo = more nutrients for phytoplankton = more krill = more whales...and so on. A side product, of course, is more phytoplankton = more photosynthesis = more sequestration of carbon...etc. And figuring out how to reverse desertification by producing more food in a manner that is more closely aligned with the evolutionary biology of the animals we use for food (i.e. have them as massive herds of wandering herbivores) seems like a really sensible approach. I reckon we still probably need to have a lot more trees (natural and/or artificial) though - and try our best not to offset the ecological gains we might make by these measures by profligate use of the resources at our disposal (i.e. we still need to balance our way of life with natural cycles that have sustained life on earth for 3.8 billion years rather than trying to conquer them).
I am awe struck at the ecological systems that are in place both on land and in the oceans. As you said, these natural cycles have sustained life on this planet for perhaps millions of years......yet with the appearance of man, when he lived according to these natural cycles, they and the land were not affected.....they existed harmoniously......but as soon as science began to dominate man's thinking, selfish and ego-driven concerns took over, and financial benefits and personal glory began to influence his activities....the earth itself then began to be affected by his interventions in a very negative way.
Vast quantities of earth's resources were taken with no concern for any impact on the planet or its population...the prime concern was impact on corporate bank accounts. Oil, coal and gas were over-utilized to the point where man's entire lifestyle became dependent on them in wealthy nations. Supply and demand meant that supply came at a greater cost than the earth can sustain. Science and the godless thinking that it promotes (no power higher than themselves to answer to) are responsible for the ecological problems faced by everyone today. Plastics (a by-product of the petroleum industry) are clogging up everything. Science seems to be in no hurry to clean up its own mess.
So....how clever are the scientists really? Any intelligent person with scientific knowledge can surely predict what will happen. They predict so much with their evolutionary theory.....yet they failed to predict (or was it failed to notify) an unsuspecting public where their selfish schemes would take the entire human race, now threatened with extinction through man's mismanagement of his only home. If pollution doesn't kill us then nuclear war might....both can be placed squarely at the feet of science and man's unscrupulous use of it for selfish advantage.
Humans justified the killing of whales in thinking that the less whales there were, the more food would be available to a diminished population....but the opposite is true. This demonstrates how short sighted humans can be when it comes to evaluating anything. Human thinking is so often flawed...as time tells us every time.
The cricket thing is obviously utter rubbish. In any case, if God wanted us all to be shepherds he could have sent the real heavenly chorus (he did that once, you may recall) rather than waiting for us to develop the technology to slow down and rearrange the discordant chirping of creepy crawlies - don't you think?
LOL.....If you see my last post, you will see that "the cricket thing" wasn't rubbish at all. Even when someone tried to imply that it was a hoax by recording a single cricket, you can hear what one cricket sounds like when slowed down 800 times. Place them in a chorus and it appears to be genuine.
Nevertheless, I am puzzled as to why you would think that there would be all shepherds and no sheep?
The harmonic sounds of nature are a gift to us. There is nothing I like more than to sit around a campfire and listen to the crickets and frogs....or to walk through a rainforest and hear the sound of the birds......it creates an inner peace so lacking in today's noisy and stressed world.....don't you think?
