The World's Greatest Environmental Health Risk for Air Pollution WHO said
Nine out of ten people breathe polluted air every day. In 2019, air pollution is considered by the WHO as the biggest health risk.
Microscopic contaminants in the air can penetrate the respiratory and circulatory systems, damage the lungs, heart and brain, killing 7 million people each year from premature diseases such as cancer, stroke, heart and lung disease. About 90% of these deaths are in low- and middle-income countries, with large numbers of emissions from industry, transport and agriculture, as well as dirty stoves and fuel in homes.
The main cause of air pollution (burning of fossil fuels) has also contributed significantly to climate change, affecting human health in various ways. Between 2030 and 2050, with climate change, it is estimated that there will be 250,000 additional deaths per year, malnutrition, malaria, diarrhea and fever.
In October 2018, WHO held its first global conference on air pollution and health in Geneva. Countries and organizations have undertaken more than 70 commitments to improve air quality.
This year, the UN Climate Summit in September aims to boost climate action and ambition around the world. Even if you make all the commitments between the countries to the Paris Agreement, the world is still going to warm to more than 3 ° C in this century.
