Le Pétrole
Le pétrole est une huile minérale d’origine naturelle composée d’une multitude de composés organiques, essentiellement des hydrocarbures, piégée dans des formations géologiques particulières. Il permet, une fois raffiné, de produire divers carburants, comme l’essence ou les diesels, des gaz, butanes et propanes et divers combustibles. Il est classé dans les ressources énergétiques fossiles. Source : wikipedia

The Anthropocene defines Earth's most recent geologic time period as being human-influenced, or anthropogenic, based on overwhelming global evidence that atmospheric, geologic, hydrologic, biospheric and other earth system processes are now altered by humans.
The Anthropocene defines Earth's most recent geologic time period as being human-influenced, or anthropogenic, based on overwhelming global evidence that atmospheric, geologic, hydrologic, biospheric and other earth system processes are now altered by humans. The word combines the root "anthropo", meaning "human" with the root "-cene", the standard suffix for "epoch" in geologic time. The Anthropocene is distinguished as a new period either after or within the Holocene, the current epoch, which began approximately 10,000 years ago (about 8000 BC) with the end of the last glacial period.
