Writing task. Question: "Increasing the price of petrol is the best way to solve growing traffic ans pollution problems. To what extent do you agree or disagree? What other measures do you think might be effective?" Ou society definitily needs to fin a sollution for the transportation issues. In fact, I had never thought in more expensive petrol as a way to achieve this. I think it actually could help but wouldn't solve the problem. Because it wouldn't change the way the population thinks and wouldn't offer other possibilities to them. I believe that the first step to change traffic an pollution situations is to help everybody to understand why it is important. People have to know that we can't live this way anymore.Unless we change, the planet is not going to last for so much time.Other cultural problem that we need to solve it is the idea that everybody have to get their own car. In some cases, people buy a car not because they need but just to have the social status they want. That is, we have to stop buying cars just to show that we can. In the other hand, the government has to do his part which is to offer good public transportation. A lot of people don't use the bus or the subway because they aren't good. In fact, just a few cities in Brazil have subway or urban train and, in the most small cities there is no public transportation at all. The bus, which is used in medium and big cities is often old, expensive and late. In addition, it has it has to share space with the cars what doesn't help the traffic and they're also very polluent. It is also essencial to find new energy sources. So, increase petrol's price could help, but it's fundamental to get free os fossil fuels, develope good public transportation, and, specially, change our minds and take care of our planet. *** This is an exercise for an exam. I've already found a lot of mistakes, but I would like to have more feedback to know exactly what I have to improve.
