1 in 9 Deaths are from Air Pollution & Trump is making it Worse

The Tree | – –

Air pollution is driving a global public health crisis. It is responsible for one in nine deaths worldwide, and touches everyone given 92% of the human race live in places that do not meet World Health Organisation guidelines. As it is also driving a climate crisis – with increasingly heavy health implications – doctors, nurses, public health practitioners and other healthcare professionals are coming together to call for practical solutions to cut pollution levels in cities and deal with both.
In a new global initiative called Unmask My City, these health groups are using air quality monitors, smartphones, and innovative LED light masks that change colour according to pollution levels to highlight the preventable and direct impacts of air pollution. These include asthma attacks, increased risks of heart disease, lung cancer, respiratory diseases and strokes, and climate change-related heatstroke, tropical disease spread, and more. The sources of and solutions to air pollution are clear. It is up to authorities to make better choices to reduce greenhouse gas emissions and get our cities into the World Health Organization’s green “healthy” air zone by 2030.

Air pollution is responsible for 6.5 million premature deaths per year. Doctors are at the front lines, and see the increasing impact air pollution has on patient mortality and morbidity. They are now speaking out globally, like they did with cigarette smoking, to demand action from decision makers on this absolutely preventable threat to public health.

Air pollution is not just a problem for China or India. The world is becoming increasingly urban, and as it does our urban environments are becoming more and more polluted. In 1800, only three percent of the world’s population lived in urban areas. Today, more than half do, and by 2050 two-thirds will. Thousands of cities around the world already consistently breach air pollution limits, and this problem will worsen without concerted action.

Eliminating air pollution is a health, climate, and economic imperative. Improving air quality and ‘unmasking’ our cities will save millions of lives, improve the health of billions, reduce health costs, drive new economic opportunities, and address the challenge of global climate change. Solutions to reduce urban air pollution are some of the most effective ways to tackle climate change in the near term. Turning around the global trend of increasing climate pollution by 2020 with the intent on reaching World Health Organization guidelines for healthy air by 2030 is critical to avoiding unmanageable levels of climate climate in the future.

Doctors were pivotal in the anti-tobacco campaigns of the late 20th century, not only helping people understand the risks of cigarette smoking, but building a compelling case to propel decision makers into action, and ensure a healthier future for people in countries all over the world.

Just like the anti-tobacco campaigns of the late 20th century, doctors are sounding alarms about the health risks of poor air quality in our cities, and through the Unmask My City initiative are aiming draw attention to the public health crisis air pollution is driving.

Air pollution drives direct health impacts like increased risk of heart disease, asthma attacks, lung cancer, respiratory diseases and stroke; and also indirect threats like heatstroke, tropical disease spread and more through its contribution to global warming. The Lancet Commission for example released a report in 2015 that not only reaffirmed the severity of the threat climate change poses to global health, but labelled it a “medical emergency”. The Lancet showed that tackling the crisis could be the “greatest health opportunity of the 21st Century”, especially considering it could undermine the last fifty years of gains in development and public health.

To highlight the global nature of this problem, Unmask My City groups are conducting “community monitoring” activities, and mapping personal exposure to bad air using AirBeam air quality monitors and the AirCasting smartphone app by US NGO HabitatMap. However, while soupy pollution in China and India makes headlines, bad air remains a largely invisible problem. To demonstrate that even clear skies can hide risky levels of air pollution, Unmask My City also makes use of custom-built LED light masks that change colour according to how good or bad the air is.

The AirBeam measures PM2.5 particulates and provides estimates of micrograms (one-millionth of a gram) per cubic meter air (µg/m3). The scale it uses is based on the revised Air Quality Index for PM2.5, and the colours mean:

  • Green: Good quality air with little to no risk.
  • Yellow: Moderate risks for those unusually sensitive to air pollution.
  • Orange: Unhealthy for sensitive groups
  • Red: Unhealthy for everyone, with sensitive groups potentially facing serious health effects.

Using the AirBeam and light masks in Turkey, the USA, Poland, Serbia, India, Brazil, and the UK, we found that despite there being a number of clear days where particulate pollution stayed in the green, more often than not it consistently dipped into the yellow, orange and red, showing risky and unhealthy levels of pollution.

The reasons for this vary between cities – some face problems from traffic pollution, others from heavy industry, some from reliance on dirty coal power, and others from low stack emissions such as coal boilers for heating – but the result for all is the same: regular exposure unhealthy air for their citizens. As the world is becoming increasingly urban, with more than half of people living in cities today and two-thirds by 2050, it is little wonder that increasing numbers of people worldwide are being regularly exposed to urban air pollution.

This problem will worsen without concerted action. Fortunately, we have the knowledge, the technology, and the global understanding that cleaning up our planet is not a choice, but an urgent necessity, and the rewards for action are tremendous.

Many policies to address air pollution and climate change are “no-regret”, in that they will reduce ill health, enhance resilience, alleviate poverty and address inequality. For example by investing in clean energy over fossil fuels, and in public and active transport over internal combustion engine cars governments will not only be reducing the climate threat, immediately improving air quality and reducing respiratory and cardiovascular illnesses, but will also be supporting technologies already shown to improve the lives of the world’s poor faster and cheaper.

Everyone has a right to safe, clean air, and that means air pollution levels must be brought in line with World Health Organisation safety standards in our cities. To get there by 2030, we need practical solutions and tangible city level policy changes to drive a clear, downward global trend in urban air pollution. This will save millions of lives, improve health outcomes for billions of people, and make a huge contribution to greenhouse gas reductions needed to keep the world safe from climate change crises.
