Question

The ultimate environmental hazard or the most outstanding danger for the survival of living beings on this planet is

• A. Radiation hazard
• B. Glaciation
• C. Deforestation
• D. Desertification

Answer 1

The correct option is A Radiation hazard

Nuclear pollution is extremely hazardous in nature. It occurs as a result of nuclear explosions that are performed during nuclear tests. The explosions cause the release of radioactive material into the stratosphere from where they fall into the earth's atmosphere.The smallest particles of the radioactive material called fallout settle on the leaves of plants and trees. These leaves are eaten by the grazing animals. Hence radioactive material enters the ecosystem. Humans consume these particles through the food chain leading to cancer and genetic mutation. Genetic mutations have long-term deteriorating effect. Fallouts may also accumulate in the seas that harm fishes and ultimately humans. Hence radiation hazard or nuclear pollution is the most dangerous for the survival of living beings on this planet. Thus the correct answer is option A.
