The most alarming of man's assaults upon the environment is the contamination of air, earth, rivers
and sea with lethal materials. This pollution is for the most part irrevocable; the chain of evil it initiates
is for the most part irreversible. In this contamination of the environment, chemicals are the sinister
partners of radiation in changing the very nature of the world; radiation released through nuclear
explosions into the air, comes to the earth in rain, lodges into the soil, enters the grass or corn, or wheat
grown there and reaches the bones of a human being, there to remain until his death. Similarly,
chemicals sprayed on crops lie long in soil, entering living organisms, passing from one to another in a
chain of poisoning and death. Or they pass by underground streams until they emerge and combine
into new forms that kill vegetation, sicken cattle, and harm those who drink from once pure wells.
It took hundreds of millions of years to produce the life that now inhabits the earth and reach a state of
adjustment and balance with its surroundings. The environment contains elements that are hostile as
well as supporting. Even within the light of the sun, there are short-wave radiations with power to
injure. Given time, life has adjusted and a balance reached. For time is the essential ingredient, but in
the modern world there is no time.
The rapidity of change and the speed with which new situations are created follow the heedless pace of
man rather than the deliberate pace of nature. Radiation is no longer the bombardment of cosmic rays;
it is now the unnatural creation of man's tampering with the atom. The chemicals to which life is asked
to make adjustments are no longer merely calcium and silica and copper and all the rest of the minerals
washed out of the rocks and carried in the rivers to the sea; they are the synthetic creations of man's
inventive mind, brewed in his laboratories, and having no counterparts in nature.
2.1. On the basis of your understanding of the above passage, make notes on it using headings
and sub-headings. Use recognizable abbreviations (wherever necessary-minimum four).​
