Degradation of Ecosystem
Ancient man was simple-minded food gatherer and hunter. He looked upon nature with awe and respect and in fact he worshipped it. But from the time he began to use his superior intelligence and began to understand nature, he became progressively self-centred and in the process started disrespecting and destroying /degrading the natural environment.
Today, he is attempting to dominate nature, shape the environment to suit himself and use everything around him for his benefit. And he has not thought much about the fragile balance of the nature. Only in the past two or three decades, as some of the ominous signs of environmental degradation have started showing up, has man realised the gravity of the situation. It has now become very clear to him that the humans should not put the planet earth, which is the ecosystem that he lives in, in an impossible position, so that a point of no return is reached.
