Underground waters resist forced depollution
Underground waters resist forced depollution
An experiment has demonstrated the role played by micro-organisms in the degradation - without oxygen - of a very common pollutant: vinyl chloride. The traces of human industrial activity persist deep inside the ground. And sometimes for a long time! In Switzerland alone, the Federal Office for the Environment records no less than 50,000 polluted sites, including 4000 that have been declared "contaminated" and require clean-up operations.

Climate impact on ancient societies
Climate impact on ancient societies
Annual-resolved European summer climate has, for the first time ever, been reconstructed over the past 2,500 years. Tree rings reveal possible links between past climate variability and changes in human history. Climate change coincided with periods of socioeconomic, cultural and political turmoil associated with the Barbarian Migrations, the Black Death and Thirty Years' War.
