Over the last few decades our world has advanced to an unimaginable rhythm however it did not bring just scientifical discoveries and healthcare improvements, it also brought serious issues, one of them being pollution, some argue that the best way to solve pollution problems it's by increasing the price of petrol which would lead to solving traffic and thus pollution, I agree with the statement but even so, I believe that there are other measures that we can take to limit contamination to the minimum possible.
