In recent times, there has been much hue and cry about the air pollution in India. Every day, we come to know about alarming air pollution levels in different parts of the country especially in the northern India. But do you know that air pollution is actually shortening our lives? Yes, this is true that air pollution has been known to shave months, and even years in some cases off your life expectancy, depending on your location, according to a study.

Worldwide, outdoor air pollution decreases the average life expectancy at birth by one year. The effect is much more distinct in some regions. For example, it curtails the average Egyptian’s life span by 1.9 years and the average Indian’s by 1.5 years. In Russia, it’s around nine months.

As air is integral to our life, we can’t think of have a life without air. This is why everyone around is too much concerned about the rising levels of air pollution. Air pollution is broadly classified into two categories – outdoor air pollution and indoor air pollution.

The major sources of air pollution are:

  • the combustion of fossil fuels, such as coal to produce electricity for homes and businesses, or petrol and diesel to fuel our cars, buses, ships and planes
  • industrial practices, especially from the chemical and mining industries
  • agriculture, which is a big source of methane and ammonia
  • waste treatment and management, predominantly landfills
  • unhygienic indoor cooking and heating systems, a critical problem in the developing world
  • volcanic eruptions, dust storms and other natural processes

These sources emit out a variety of substances including carbon monoxide, carbon dioxide, nitrogen dioxide, nitrogen oxide, ground level ozone, particulate matter, sulphur dioxide, hydrocarbons and lead – all of which are found to be disastrous to human health.

The destructive effect of air pollution weakens the general progress that the world has made in rising life expectancy in the past decades. The global average is 72 today, about 20 years better than it was the year 1960. Better access to health care has been a critical factor in bringing that difference.

Both indoor air pollution and outdoor pollution can be termed as culprits behind one of nine deaths worldwide.
