There are some arguments for the productive of reducing air pollution by international car-free days. While I accept this solution can tackles the problem, I believe there are another methods to solve this problem.
No doubt that international car-free days could be the most effective short-term solution. The primary reason is that it could raise the international awareness of pollution. People who accept this solution could not use car for a day or several days. Therefore, the emisson which release from individual vehicals have plummet significantly and contribute to a reduction in air pollution. However, this short-term solution still have some drawbacks that this is not an completely resolve. People who use individual car for transportation could continue traveling after a few days. The reason is simple, they cannot change their behavior by the trend and changing from car using biodiesel to green energy cost a lot.
In the contrary side, there still have a numerous solutions could tackle air pollution. Reffering to the first method, government should motivate residents to use public transportation rather than the individual one. the reduction of the quantity of individual car leading to the pluge of air pollution. The less people traveling by their own car, the less emisson release to the atmosphere. Regarding the second method, government should formulated a policy on changing car, people who change the biodiesel car to green energy car could gain assitance. This is a long-term solution to deal with the air pollution, it can take several years to strike of the individual car. However, it benefit to the atmosphere is considerably.
In conclusion, I firmly confirm that despite international car-free days could be really effective for the short-term solution, there are a plenty of solutions can tackle this problems in the long-term.
