|
Answer» Women and communities have played a major role in environmental conservation movements. Case study of the bishnoi community: The Bishnoi community in Rajasthan strictly believes in the concept of living peacefully with nature. In 1731, the king of Jodhpur ordered his ministers to arrange wood for the construction of his new palace. For this purpose, the minister and the workers went to bishnoi village. There, a Bishnoi woman called Amrita Devi along with her daughter and hundreds of other Bishnois showed the courage to step forward and stop them from cutting trees. They embraced the trees and lost their lives at the hands of soldiers of the king. This resistance by the people of the village forced the king to give up the idea of cutting trees. Chipko movement: The Chipko movement was started in 1974 in the Garhwal region of the Himalayas. In this movement, the women from the village stopped the contractors from cutting forest trees by embracing them. |

Why is it desirable to use unleaded petrol in vehicles fitted with catalytic converters? |
|
Answer» Catalytic converters, having expensive metals namely platinum, palladium and rhodium as the catalysts, are fitted into automobiles for reducing emission of poisonous gases. The exhaust passes through the catalytic converter and unbrunt hydrocarbons are converted into carbon dioxide and nitrogen gas, respectively. Motor vehicles equipped with catalytic converter should use unleaded petrol because lead in the petrol inactivates the catalyst. |

DDT residues are rapidly passed through food chain causing biomagnification because DDT isA. lipid solubleB. moderately toxicC. non-toxic to aquatic animalsD. water soluble |
|
Answer» Correct Answer - A Many of the pesticides, such as DDT, aldrin and dieldrin are accumulated in the environment. They are fat soluble and generally non-biodegradable. They get incorporated into the food chain and ultimately deposited in the fatty tissues of animals and humans. In the food chain, because of their build up, they get magnified in the higher trophic levels called biological magnification. The phenomenon of biological magnification is also reported for certain other pollutants such as, heavy metals, e.g., mercury, copper and radioactive substances as strontium-90. |

Answer» Correct Answer - D DDT, its breakdown products and other chlorinated hydrocarbon pesticides pose serious threat to birds. These persistant poisons enter the food chain and they accumulate in the fatty tissues of organisms at lower trophic level and then tend to concentrate in considerably toxic amount as they move up through the food chain. This is called biomagnification or bioconcentration. It weakens the calcarious egg shell of birds as it becomes very thin. |
