This will depend on how electric cars/vehicle will perform against vehicles that runs using petrol products. But for me if they can perfect elecric vehicles . it will not only threaten oil industry it will also help lessen pollution.
Yup you have the point that it can help lessen the polution but others think that the important is the government because if the oil industry lose many costumers, many people removed from their work and many companies that can lose many Money so if that happens they cant pay the tax.. If they cant pay the tax the government will lose many funds for their projects.
