PODCAST #48 | Anthropogenic mass: Artificial materials already have more weight on planet Earth than living beings.

• Until 120 years ago, the mass of all human-modified artificial materials for thousands of years did not exceed 3 per cent of the total mass of living beings owned by planet Earth. Since then, thanks in particular to the “Great Acceleration” started in the 1950s, the world has suffered a total artificialization, reaching the weight of both sets in 2020. If things go wrong, by 2040 it will be three out of four tons of the planet's surface.
