Answer:
Some government leaders consider fracking is socially inefficient because fracking not only has environmental hazards but also effects the social life of people which indirectly also effects their health.
Fracking is the act of drilling chemicals and water deep into the grounds and rocks with high pressure which in turn releases the underground gas reservoir. This uses a large amount of water supply.
People living near the fracking sites have to suffer through environmental change and shortage of water specially in drier seasons. This is also a cause for mental and physical health deterioration.
