WHY PRESERVE BIODIVERSITY ?
Prof. D. Balasubramanian
1. Why does the author say that it is our moral responsibility to protect diversity?
Since humans rule this planet, it is necessary for him to protect diversity. Humans are superior creatures who have the aesthetics and ethics to protect all that the earth holds.
Their majesty and beauty charm humans to accept and appreciate them.
3. What is the utilitarian aspect of biodiversity?
Man has to depend on nature for agricultural, textile and housing needs for his survival.
The natural ecosystem depends on the network of a diverse range of organisms and species for survival. This interdependence is like a spider web. The disturbance of even one strand of the web will result in total collapse.
The prime rule of ecology is that everything depends on everything else.
Since even the most inconspicuous creature is important in the network of interdependence of nature no species should be pushed to extinction.
Anthropocentrism is the belief that human beings are the central and most significant species on the planet who supports utilitarian causes.
ANSWER IN A PARAGRAPH
1. Why does the author say that the loss of biodiversity should be a concern for us for ethical and aesthetic reasons?
Humans rule this planet. So it is the responsibility of man to protect all matter of nature. Unless we protect nature, the beauty and utility of nature cannot be passed on to the next generations. It is only practical to responsibly preserve what has been bestowed on use because man is both aesthetic and ethical.
Man borrows extensively from the warehouse of nature for his agricultural, medical, clothing and housing needs. Additionally his survival depends on the balance of the nitrogen level in the atmosphere that is balanced by rhizobium. Man still hasn’t been able to completely and fruitfully utilize the majority of the abundance of nature.
3. What were the various reasons for the biotic degradation?
There are majorly five reasons of biotic degradation caused by man: 1. Hunger and poverty, 2. Short term gains and long term failures, 3. Anthropocentrism, 4. Economic pressures on certain communities and 5. policy factors.
ANSWER IN 200 WORDS
The first reason for the loss of biodiversity is man’s indifference toward his ethical and aesthetic responsibility of protecting nature. Since he rules the planet it is his duty alone to strive to maintain the balance.
The second reason is his utilitarian characteristic that makes him depend on nature. Though there is abundance in the planet at his disposal, his inefficiency in recognizing and utilizing the richness leads him to overuse few things and underusing or ignoring the majority. This has resulted in an imbalance in nature.
The third reason is his inability to maintain the ecological network. His anti-pragmatic approach toward utilizing the diversity has resulted in misusing nature. Man’s population pressures, leading to hunger and poverty, have lead way to deforestation. His attitude of gaining in short period of time and failure to see the long term benefits makes him strip mine and cut down trees of value for trading. His purely utilitarian attitude has made him indifferent toward his responsibility of conservation of the ecosystem. Economic pressures of certain communities have resulted in loss of tropical forests. Civil issues as well have affected the ecosystem considerably. Man, in short, has created a total imbalance in the ecosystem by not adhering to the principle responsibility he had been trusted with.
