What do you suppose is one of the largest single causes of premature death in the world? It would be easy to assume it's violence like war and murder. But recently, war and murder killed less than a million people worldwide in 2015.
Tobacco And Assorted Diseases
There are other things that killed a lot more than that. The next natural assumption would be diseases like AIDS, malaria, and tuberculosis.
Those killed about three million people in 2015, but still weren't the biggest killers.
Another good guess would be tobacco smoking and health issues arising from that. But it's not that either, although it is estimated that tobacco killed killed seven million in 2015.
It's pollution. A 2017 study conducted by the medical journal, The Lancet estimated that nine million people died due to pollution of air, water, soil, and workplaces worldwide.
That's sixteen percent of all global deaths. The biggest single culprit is air pollution. The researchers also estimated all the consequences of this pollution costs more than four trillion dollars every year.
The Link Between Pollution And Global Poverty
They discovered things are that bad by combining data from many different published sources. Another finding was pollution and global poverty are closely linked.
The overwhelming majority of pollution deaths happen in poorer countries like India, China, and Southeast Asia, and the economic costs of pollution are a big drag on the economies of developing countries. Most of the deaths happened in urban areas.
Studies like this one are valuable. Now that we know what the problem is, we can begin to take action.
