increasing the price of petrol is the best way to solve growing traffic and pollution problems

there are various causes which are badly affecting the environment and causing global warming one of them is pollution there are different kinds of pollution air pollution noise pollution water pollution etc one of the most dangerous pollution is air pollution which is destructing the environment.
As the statement is illuminating that pollution could be under control by increasing the prices of petrol for my concerned I am not agree with it.
High prices of petrol will enormously hit the economy of a country prices of all the things will go up like prices of food, clothes, and fares of vehicles e etc.
For instance I take an example of under developed country (Pakistan, India etc) .Pakistan is an underdeveloped country where poverty rate is more than 50% if the price of petrol will raise then people would be unable to meet their basic needs.
So high petrol price is not an appropriate solution other precautionary measures could be adopted for the prevention of pollution like wise to avoid water pollution there should be proper sanitary system of water any kind of wrapper or garbage should not put into the water as for as air pollution is concerned we should avoid those kind of vehicles which are on petrol .new electric cars should be introduced govt should make some rules against issuance of cars definitely if people will have less cars then how pollution problem will rise.
To conclude that high prices of petrol are not linked with pollution both are separate issue petrol is highly linked with economy while pollution is linked with environment both are crucial by increasing or decreasing one aspect we cant sort out solution of any problem to control pollution some comprehensive and substantial rules should be implicated
