Question

Reducing friction to the lowest possible level in machine tools solves the problem
of energy crisis and conserve biodiversity. How do you support the statement?
Explain? (AS)​

Answer 1

Answer:

When more energy is used, we need to burn more fuels like coal and petroleum that further pollutes the environment. ... So, we conclude that reducing friction to the lowest possible level in machine tools solves the problem of energy crisis and conserves biodiversity.

Answer 2

Answer:

Due to more friction the vehicles let out a huge amount of smoke which pollutes the atmosphere.

If we reduce the friction to the lowest possible level, this pollution can be prevented so that we can save biodiversity. The machine tools also let the same problem.
