The following submission statement was provided by /u/darth_nadoma:

The report stresses that without urgent action on clean air, the financial cost of air pollution in Africa’s cities is predicted to increase by more than 600 per cent by 2040. Studies show that Africa’s cities are likely to house 65 per cent of its population by 2060.

Air pollution killed 1.1 million Africans in 2019, while AIDS related diseases killed 440 thousand.
