Question

what will happen if we will not stop pollutions

Answer 1

Concerns about the quality of the air we breathe have long been an issue in Britain. As far back as the 13th century, legislators outlawed the combustion of coal for fear of the frightful fumes it released. Of course, the economic benefits ostensibly outweighed the environmental and health concerns, and humanity has leapt from one pollutant practice to the next in the intervening near-millennium.

Should air pollution go unchecked, we can expect our skies to become foggier and our oxygen harder to breathe. Not only will this mean personal discomfort and hazard (as is already experienced by more than a billion people in China and other Asian countries), but could also play havoc with agriculture. Mouting levels of CO2 in the Earth’s atmosphere would raise temperatures, melting the polar icecaps and raising sea levels. Furthermore, over-pollution of the skies would eventually block out the sun, not only leaving us cold and dark, but without any way of growing crops and feeding livestock. As well as the direct threat to our survival this obviously poses, it would also threaten our economy
