Question 4 of 5
4. Question
Passage
Desertification is a huge global environmental problem — like climate change. Desertification adds to, and worsens the impact of climate change. Currently, some two billion people are affected by desertification and the degradation of land; 41 per cent of the landmass worldwide is prone to desertification. The major deserts in the world are expanding at an alarming rate. Deserts in China, Mongolia and Africa are all invading their neighbouring regions.
- With reference to above passage, following implications have been considered:
- Fewer and fewer hectares would be available for agriculture and livestock
- There will be cuts in availability of food and water
- Disasters such as sandstorms will wipe out large swathes of habitable land
- Aquifers may vanish and biodiversity might greatly reduce
Which of the above implications is/are practically and logically valid?
Correct
Correct Answer : D
This is a tricky question. Only statement 1 will seem to be direct implication. But there is no such option. So extrapolated thinking is needed to choose any option. All options have 2 so its correct. Logically acquifiers will vanish as it is said decertification is spreading. If we go for extrapolation it is logical to consider that sandstorms may occur since desertification increases its frequency.
