Why little things matter? Minuscule particles in the air, called soot, cause more than 300,000 deaths a year in Europe alone. If we don’t reduce soot emissions now, in 40 years time the North Pole will be under water. Soot in Europe mainly comes from unfiltered diesel engines. It’s technically feasible to fit effective particle filters in diesel engines to stop the problem. See video for full explanation of this issue.
