In the world there are 27 mega-cities (with a population of more than 10 million people). As found out a group of scientists from the University of Toronto (Canada), they consume a total of 9% of the global volume of electricity, 10% gasoline. They produce 13% of global waste. The leader of this list is New York. Every year, its residents and visitors leave about 33 million tons of garbage. This is nearly three times greater than that of Tokyo, in which a list of cities ranked second waste. The average New Yorker spends twice as much electricity than a resident of Kolkata (Calcutta) in India.

According to him, when the population gradually gets richer, it logically begins to consume more and, consequently, produce more waste.
