Kanpur was named the world's most polluted city in WHO's list. Greenpeace mentioned that air pollution in almost 22 cities of Uttar Pradesh were not meeting the national ambient air quality standards.

Pollutants in Kampur are more dangerous than thoses found in other cities around the world and they could badly affect people´s health. Conversely Bamenda in Cameroon and Baoding in China have more gases but those ones are more controllable.

Size's Particulate matter 2.5 is the most dangerous particle in the air, because it causes asphyxia, asthma and in a lot cases, cancer.

Population is another contamination factor, because people emit greenhouses gases in activities such as producing more trash, driving a car, cooking, in their work places, etc. for that reason, particulate matter tends to accumulate in cities.

If cities had enough trees, there would be fewer toxic gases in the atmosphere and people could live healthier or maybe if they were more environmentally sensitive, they would begin to recycle and implement more sustainable practices.

We could be better than our ancestors, if we improve our awareness and create new ways to live and consume, but if we don´t change now, we and the next generations will not live a good life in the future.
