Dear Shri Raghy,
The nature has its logic. A carnivore killing a herbivore is not destructive. We humans without understanding the intricacies of nature try to tamper with it. Hence unintended and harmful consequences. With just a little intelligence and power, we are still far away from understanding nature fully to comment on the natural phenomena.
Dear Sri. Sravna,
It is not very hard to understand the basic principle of nature.
The basic principle is, nature is always in a state equilibrium. This universe is always in motion. Something is happening all the time in the universe. The resultant product.... the net result at any given moment is zero.That is the equilibrium.
Nothing happens in nature to destruct or to produce.... all these actions taking place all over the universe makes nature. We can't tamper with nature, but we are the nature.
