Question 1.
Pretend that you live in prehistoric times on a high windy plateau. What are the uses you and your friends could put the fast winds to? Can you call the wind a resource?
Now imagine that you are living in the same place in the year 2138. Can you put the winds to any use? How? Can you explain why the wind is an important resource now?
Answer:
In prehistoric times: When the fast winds start blowing we would try to hide in caves or behind rocks to protect ourselves. In this case, winds cannot be called a resource because we are scared of fast winds and they are of no use to us.

In the year 2138: Energy (in the form of electricity) is generated using windmills. For this purpose, wind farms have been established. In this case, the wind is an important resource because it has utility and economic value. With the help of technology, it is used to satisfy a need. Energy generated in windmills is used to run small-scale industries and for domestic purposes.
