It is widely reported that the raise of the number of individual cars has resulted in high pollution level in many cities of the world, and there are suggested a great many measures for solving the problem nowadays, and in this essay, I intend to discuss some very popular approaches for improving the situation on the whole.
First of all, it is an indisputable fact that one probable solution would be to improve internal combustion engines by using different turbo technologies as well as catalytic converts and filters, as their combination will reduce significantly total emission including nitrogen dioxide, sulfur dioxide and carbon monoxide. For instance, the scientists proved the fact that an internal combustion engine with a turbine does put into atmosphere a third less harmful exhausts.
Secondly and even more importantly, using electric cars in large scale could be beneficial for environment either, and one salient example of it would be different cities of China where such an approach for solving the problem led to significant improvement in quality of air there. However, this technology is considered to be controversial, since the thermal power plants (TPP) producing electricity release into atmosphere harmful exhausts as well.
Another possible tackling of the problem might be the improvement of public transport and doing it more comfortable and attractive for society. For example, since public transport is well developed in Europe, we can see few private cars in the big cities of Europe.
By way of conclusion, I would state that just a single measure alone will definitely not be enough for improving of the situation, and only comprehensive and multilateral approach will bear fruit.
