Passage Reading and English Comprehension

Read the following passage and answer the questions based on it

The assault on the purity of the environment is the price that we pay for many of the benefits of modern technology. For the advantages of automotive transportation we pay a price in smog-induced diseases; for the powerful effects of new insecticides, we pay a price in dwindling wildlife and disturbances in the relation of living things and their surroundings; for nuclear power, we reisk the biological hazards of radiation. By increasing agricultural production wiht fertilizers, we increase water pollution.

The highly developed nations of the world are not only the immediate beneficiaries of the good that technology can do, they are also the first victims of the environmental diseases that technology breeds. In the past, the environmental effects which accompanied technological progress were restricted to a small place and relatively a short time. The new hazards are neither local nor brief. Modern air pollution covers vast aeas of continents. Radioactive fallout from nuclear explosions is worldwide. Radioactive pollutants now on the Earth' surface will be found there for generations, and in the case of Carbon-14, for thousands of years.
