On some days of the year there is a cumulative effect of bad influences on air quality in Europe. Cold winter temperatures increase emissions from heating. Outdated heating with coal, still important in Eastern Europe, causes high amounts of extra particles in the atmosphere. In January 2024 a train conductor strike in Germany irrespective of the good reasons for it, makes people take their cars. Road blockades by opponents to reducing diesel subsidies to agri-business add to the pollution situation on a specific day. Overall the population suffers and breathes additional amounts of cancerous particles. Particles settle as dust on crop producing soil, of which we all feed ourselves. This is a vicious circle, which we need to break in the interest of all of us, particularly for the more fragile people and children. The latter start to crowd the medical doctors with sometimes lacking the delivery of crucial medicines for this target group. Where do we go from here? Compromises are key, security of supply chain and allowing, not too much, time for transition periods.
