The European Green Deal and its zero pollution agenda set ambitious goals to safeguard nature, the climate and people’s health. Reducing and preventing pollution improves quality of life and prevents illness. Some would argue that this is too costly. But it is done to protect ecosystems that our societies depend on and to protect our own health. Both in the case of ecosystem health and people’s health, it is far cheaper and much more effective to prevent damage than to repair it. It is simply a good investment for the future – and something that the polluters should pay for.
