What an Atmosphere!

It has been claimed that air pollution is now the biggest health hazard across the EU, with around 400,000 people per year dying from conditions exacerbated by (largely) transport-associated fumes (https://www.theguardian.com/environment/2018/sep/11/air-pollution-is-biggest-environmental-health-risk-in-europe). Even more scarily, a tenth of those deaths occur in the UK, a country with a large population, a relatively small area and a strongly-entrenched car habit.
