Advancing towards Stone Age

The notion that the world around us is continuously evolving is understood by one n all , yet we rarely grasp its full implications. We do not ordinarily think...for example... that malaria or even common cold virus to be evolving as it spreads year after year and that finally we’ll stumble across a virus thats incurable by our antibiotics. Nor do we think of evolution in plants and animals as occurring in a matter of days or weeks....though it does. And we do not ordinarily imagine the green world around us as a scene of constant, sophisticated chemical warfare, with plants producing pesticides in response to attack, and insects developing resistance. But I guess that happens too.
If we were to grasp the true nature of nature—if we could understand the real meaning of evolution—then we would envision a world in which every living plant, insect, and animal species is changing at every instant, in response to every other living plant, insect, and animal. Whole populations of organisms are rising and falling, shifting and changing. This restless and perpetual change,as unavoidable and unstoppable as the waves and tides, presents a world in which all human actions necessarily have uncertain effects. The total system we call the biosphere is so complicated that we cannot know in advance the consequences of anything that we do. That is why even our most enlightened past efforts have had undesirable outcomes....either because we did not understand enough, or because the
ever changing world responded to our actions in unexpected ways.
Unfortunately, our species has demonstrated a striking lack of caution in the past. n it is hard to imagine that we will behave any differently in the future. We think we know what we are doing. But isn’t it exactly what we thought in the past. We never seem to admit that we have been wrong in the past, and so might be wrong in the future. Instead ,each generation writes off earlier errors as the result of bad thinking by less able minds—and then confidently embarks on fresh errors of its own.

“They didn’t understand what they were doing”

I m afraid that will be on the tombstone of human race...
I hope not...
