Reduced efforts to clean emissions

The acid rains have become an international problem because the heights of industrial chimneys are required to be increased to comply with the standard height norms of the regional pollution control boards.

Explanation:

To mitigate the problem of acid rains, the governments implement norms regarding the height of industrial chimneys. These chimneys are required to be constructed according to the norms set by the government. This kind of construction of the chimneys results in a considerable increase in the height of the chimneys giving to other problems. Taller chimneys need more maintenance and thus incur more maintenance cost.
