Three small globes, terrestrial and the small end of a fourth pivot on the screen of the computer. “If everyone lived like you, we would need 3.3 Land “, he wrote on the website Global Footprint Network. The renewable resources of the planet would be exhausted each year on 20 April. And after this date, then ? A credit, the vacation of the month of August ! Credit, the beef bourguignon in the winter ! Birthdays and Christmas, you put it on my note !

Ditto for the meat. It also takes into account the emissions of the services put at my disposal, public services (schools, hospitals, military barracks, courts of justice) and private (banks, etc.). Gold the Earth has an absorption capacity of CO2 limited, through its “wells” : forests, oceans.

These data are not stable and the tool of the Global Footprint Network is far from perfect, but the general idea is there : we emit too much.
