Annual Worldwide Deaths From Air Pollution

 Last fall a study came out that estimated that annually about 3.3 million deaths throughout the world were caused from air pollution. But a study was presented Friday at the American Association for the Advancement of Science (AAAS) that gave a much higher estimate of annual air pollution deaths: 5.5 million. A horrifying number. And yet... governments, companies, and people resist  measures to cut air pollution. Why? It costs money. And also many people are too poor (e.g., China and India) to use cleaner sources of heating and cooking fuel - so they are damaging their own health in their own homes. From Science Daily:

Poor air quality kills 5.5 million worldwide annually






In the last 50 years, North America, Western Europe and Japan have made massive strides to combat pollution by using cleaner fuels, more efficient vehicles, limiting coal burning and putting restrictions on electric power plants and factories. 

Additional facts about air pollution: - World Health Organization (WHO) air quality guidelines set daily particulate matter at 25 micrograms per cubic metre. - At this time of year, Beijing and New Delhi will see daily levels at or above 300 micrograms per cubic meter metre; 1,200 per cent higher than WHO guidelines..... According to the Global Burden of Disease study, air pollution causes more deaths than other risk factors like malnutrition, obesity, alcohol and drug abuse, and unsafe sex.... - Cardiovascular disease accounts for the majority of deaths from air pollution with additional impacts from lung cancer, chronic obstructive pulmonary disease (COPD) and respiratory infections. Video:
