Answer:
Frictional force causes a lot of losses in general upkeep and wear and the tearing of machinery. But almost all crucial tasks cannot be carried out without the presence of friction. Basic activities like walking and writing on a surface are possible due to friction. Hence it is considered as a necessary evil.
