Explanation: Freshwater supplies may be seriously affected due to climate change. Reducing the availability of clean water for drinking leads to the death of humans and as well as animals. It leads to drought condition.
9. How food production reduced due to climate change?
a) Due to application of organic manures
b) Due to modern technologies
c) Due to increase in pests
d) Due to reduced in pollution
View Answer
Explanation: Food production will be seriously reduced in vulnerable regions directly and also indirectly through an increase in pests and plant or animal diseases. This leads to reduce in the yield of crops and the quality of the crops also reduced.
10. How climate change leads to conflicts in vulnerable regions?
a) By shortage of human resources
b) By shortage of food and water
c) By shortage of land
d) By shortage of chemical manures
View Answer
Explanation: Food and water shortages may lead to conflicts in vulnerable regions. Due to shortage of food and water both animals and humans suffer from starvation and malnutrition with long term health consequences.
11. What happens when seasonal transmission of vector species due to climate change?
a) Increase the spread of diseases
b) Decreased the spread of diseases
c) Vector species itself die
d) Vector species do not spread disease
View Answer
Explanation: Due to change in climate vector species like mosquitoes, will increase the spread of diseases, such as malaria, dengue etc to new areas which lack good public health infrastructure and cause problems.
12. Which one of the following can achieve Global Climate Change?
a) World War-3
b) Making unwanted policies
c) Drinking less water than required
d) The training of researchers and health professionals
View Answer
Explanation: The training of researchers and health professionals is essential towards the world becoming more responsible for the expected outcome of Global Climate Change. Thus we can protect the environment.
