Um dia internacional sem carros é uma forma eficaz de reduzir a poluição do ar?

Maybe, its an effective methond to reduce the pollution to an extent. By reducing the number of cars we are actually reducing the amount of carbon dioxide. So i believe the effects it has on our environment is also reduced respectively.

I beg differ after all car pollution is not the unique culprit results in air pollution! Industrial development and weak consciousness of protecting environment for human lead to the air pollution! So we should tackle all those tissues simultaneously to fight against air pollution

Yes obviously it helps us to reduce air pollution. Because we dont ride cars on that day.

I think this kind of activities are crucial to warn people about our last chance. Actually a lot of scientists have different ideas about this topic. Firstly we should know that only one car-free day has a small impact on air pollution. In stead of this kind of short notice warnings, we must support pivotal activities which are supported not only governments but also huge conglomerates like big car firms. Secondly, in order to reduce car emission, our governments and local managers should enact important bills which are obeyed by all countries and world. Lastly, the green gas effect which is triggered by engines which are powered fuel or gas, should be eliminated step by step. These kind of cars or trucks or all vehicles should be exchanged with electrical motors or renewable energy using engines. At first glance we may out of limit to turn our predecessors time’s, but we should even struggle to reach some levels of their time’s carbon levels. So it is never be too late.

No, I don't think so. May be an international car free year....!!

An international car-free day is could be an effective way to reduce air pollution. We won’t receive a result quickly but with time I believe we will earn the success. I’m convinced that one unique day can’t change the livestyle of the people but if we celebrate this day regularly at least one time in the year it could be successfully. Because I think this celebrity gives them an important political weighting. And this political weighting I guess will be start a huge avalanche in population because the media will report about it. The social media will reflect it shortly the people will discuss about the effects of car-free-life. So they will be reduce to drive their cars or if not their might be change to an electric car for reducing air pollution. I my opinion for long term it will be effectively to celebrate an international car-free day in the word. We have only one word and we should share this wherever we could.

I think this way may help, but it must have some exceptions like ambulances, fire truck.

Nowadays, all types of pollution have become a big problem among us, air pollution is one of them. A single car- free day can be an initiative of awareness towards air pollution, definitely it can not be a permanent solution in order to curb air pollution. For example, Our lifestyle has become sluggish, Vehicle’s have taken place of active lifestyle. Almost two decades ago, for to cover short distances people were either cycled or walked on foot, but in modern society everyone likes to drive car or riding bikes for the same distance. However, there is no doubt it , air pollution has been increasing drastically for past few years, in order to control air pollution, car-free day can be a good initiative besides that all countries governments have to make some strict rules and organize some campaigns for their citizens to spread the awareness about how to control air pollution.
