Imagine that you could buy, in thousands of shops across the country, canisters containing toxic gas. Imagine that some people walked the streets, squirting this gas into the face of every child they passed. Imagine that it became a craze, so that a child couldn’t walk a metre without receiving a faceful. Imagine that, while a single dose was unlikely to cause serious harm, repeated doses damaged their hearts, lungs and brains, affecting their health, their intelligence and their life chances.
It would be treated as a national emergency. Sales of the canisters would immediately be banned. The police would be mobilised. If existing laws against poisoning children were deemed insufficient, new legislation would be rushed through parliament. It’s not hard to picture this response, is it? Yet the mass poisoning is happening. And nothing changes.
According to a paper in the International Journal of Environmental Research and Public Health, burning fossil fuels is now “the world’s most significant threat to children’s health”. Their life chances are compromised before they are born. Toxic particles from exhaust fumes pass through the lungs of pregnant women and accumulate in the placenta. The risk of premature birth and low birth rate this causes is described in the British Medial Journal as “something approaching a public health catastrophe”.
Among the likely impacts of repeated poisoning, researchers now believe, is a “huge reduction” in intelligence. A paper published last year found that “long-term exposure to air pollution impedes cognitive performance in verbal and math tests.” Pollution stunts the growth of lungs as well as minds, raising the risk of asthma, cancer, stroke and heart failure throughout a child’s life.
How will this affect the Diesel Generation: in other words, those born since 2001? This was the year in which Tony Blair’s government, rather than delivering the integrated public transport it had long promised, sought to tweak the carbon emissions from cars by taxing diesel engines at a lower rate than petrol engines. Diesel cars might produce a little less carbon dioxide, but they release more nitrogen oxides and particulates, a tendency exacerbated by the manufacturers’ cheating. An entire generation – 18 years of births – has been exposed to the results of this folly.
Given that researchers have found an association between air pollution and childhood mental illness, could this help to explain the rising prevalence of psychiatric disorders among English children since the first major survey, in 1999? A study conducted in London suggests that people with the highest exposure to pollution also have a greater risk of developing dementia. Might we have triggered a dementia time bomb, that could explode in 40 or 50 years?
The only difference between the absurd scenario with which this article began and reality is intent: no one means to poison children with their exhaust fumes. But the absence of a mens rea makes no difference to their health. The one-tonne metal canisters are still on sale (though the number bought has dipped slightly in the past year) and toxic gas is pumped into our children’s faces with every step they take.
Especially on the way to and from school. These are the times at which children inhale the most particulates (especially if they are driven – exposure is much greater inside a car than on the pavement). Horrifying recent data also reveal that pollutants from nearby roads accumulate in classrooms, leading to higher levels inside than out. Due to the continued failure of successive governments to address this crisis, taking children to school damages their minds.
This is a national emergency. In fact, as 90% of the world’s children are now exposed to dangerous levels of air pollution, it is an international emergency. So why don’t we react as we would if the poisoning were deliberate, and ban the sale of toxic gas canisters? In the UK, the government says it will end the sale of petrol and diesel cars and vans (though not buses and lorries) by 2040. Another generation poisoned. In the latest budget, it exacerbated the problem, announcing a further £30bn for roads, creating more space for toxic gas flasks.
When the government won’t act, only palliatives remain. In desperation, Sadiq Khan, the mayor of London, has started installing air filters in nurseries and classrooms. It’s as if, rather than vaccinating children against diphtheria, they were issued with face masks.
After the Lancet Commission on Pollution and Health reported, in 2017, that pollution kills more people than tobacco does, and three times as many as AIDS, tuberculosis and malaria combined, you might have hoped that governments, development agencies and health charities would have made it a priority. But they remain focused on communicable disease, while ignoring the greater, manmade threat. Where is Save the Children? Where is Medicins San Frontieres? Where are the philanthropists seeking to eliminate deaths from ambient air pollution, as Bill and Melinda Gates and others seek to wipe out malaria?
When the World Heart Federation built a global coalition to conquer heart disease and stroke, and when the charity Vital Strategies launched a similar global initiative on cardiovascular illness, with Gates, Bloomberg and Zuckerberg money, they overlooked air pollution, even though it kills more people than the factors they emphasised (such as salt and trans-fats). The same weird silence afflicts the UN Task Force on non-communicable diseases and the World Health Organisation’s global action plan. Pollution is off the agenda. Why?
I think there may be three reasons. The first is that there is no heroic narrative built around tackling air pollution, while there are plenty (Louis Pasteur, Alexander Fleming, John Snow) surrounding the fight against infection. The second is that the necessary interventions are not discrete but systemic. Rather than distributing mosquito nets or reducing the salt in processed food, you must change entire transport and industrial systems. The third is that, while no one has a commercial interest in spreading tuberculosis or polio, there is a massive global lobby, comprised of fossil fuel, motor and infrastructure companies, blocking effective action against pollution and the technologies that cause it. If you take on pollution, you take on the combined might of some of the world’s most powerful industries. Pollution is the tangible manifestation of corruption.
The solution is political: confronting the power of this lobby and overturning the governments it has captured, then replacing private cars and ever-expanding roads with electric mass transit, walking and cycling, and imposing stringent conditions on dirty industries. We have been abandoned by those who claim to defend our children from disease. So we must mobilise.
Please Help ZNet and Z Magazine
Due to problems with our programming that we have only now finally been able to fix, it has been over a year since our last fund raising. As a result, we need your help more than ever to continue to bring the alternative information you have been looking for for 30 years.
Z offers the most useful societal news we can, but in judging what is useful, unlike many other sources we emphasize vision, strategy, and activist relevance. When we address Trump, for example, it is to find ways beyond Trump, not to merely repeat, over and over, how terrible he is. And the same is true for our addressing global warming, poverty, inequality, racism, sexism, and war making. Our priority is always that what we provide has potential for aiding determining what to do, and how best to do it.
In fixing our programming problems, we have updated our system to make becoming a sustainer and giving donations easier. It has been a long process but we are hopeful it will make it more convenient for everyone to help us grow. If you have any trouble, please let us know right away. We need input on any problems to make sure the system can continue to be easy to use for everyone.
The best way to help, however, is to become a monthly or annual sustainer. Sustainers can comment, post blogs, and receive a nightly commentary by direct email.
