Pollution is an unwanted waste of human origin that is released into the air, land, and water.

The 2017 Lancet Commission on pollution and healthTrusted Source found that in 2015 alone, pollution was responsible for around 16% of deaths globally. 

Monitoring the effects of pollution on public health could help develop policies to prevent negative health consequences. 

Recently, researchers updated the 2017 Lancet Commission on pollution and health with data from 2019Trusted Source. 

Although deaths from household and water pollution have fallen since 2015, pollution still caused over 9 million deaths worldwide in 2019.
