Human activities that cause environmental degradation also have a significant impact on our health.

Data shows that overall health has been stagnant or declining in recent years.

For example, it is a paradox that life expectancy has stagnated or even declined in many countries—especially wealthy ones. The most exemplary country, in a bad sense, is the United States – and this was even before the Covid-19 pandemic.

We could use other indicators, such as infant mortality or cardiovascular mortality, which are rising in many countries, including France.

Of the risks you identified, one of the main ones is pollution, which kills 9 million people around the world every year. What type of pollution are we talking about?
