La<\/span>\u00a0<\/span>pollution<\/span><\/b>\u00a0<\/span>d\u00e9signe la d\u00e9gradation d’un<\/span>\u00a0<\/span>biotope<\/span><\/a>\u00a0<\/span>par l’introduction, g\u00e9n\u00e9ralement humaine,
\nde substances chimiques ou organiques, g\u00e8nes ou de radiations (radioactivit\u00e9,
\nlumi\u00e8re artificielle), alt\u00e9rant de mani\u00e8re plus ou moins importante sur le
\nfonctionnement de l’<\/span>\u00e9cosyst\u00e8me<\/span><\/a>1<\/span><\/sup><\/a>. Par extension, le mot
\nd\u00e9signe aussi parfois les cons\u00e9quences de ph\u00e9nom\u00e8nes g\u00e9ologiques comme une<\/span>\u00a0<\/span>\u00e9ruption volcanique<\/span><\/a>2<\/span><\/sup><\/a>.<\/span><\/p>\n

La pollution d’origine
\nhumaine peut avoir un impact tr\u00e8s important sur la sant\u00e9 et dans la<\/span>\u00a0<\/span>biosph\u00e8re<\/span><\/a>\u00a0<\/span>comme en t\u00e9moigne l’exposition aux<\/span>\u00a0<\/span>polluants<\/span><\/a>\u00a0<\/span>et le<\/span>\u00a0<\/span>r\u00e9chauffement climatique<\/span><\/a>\u00a0<\/span>qui transforme le climat de la<\/span>\u00a0<\/span>Terre<\/span><\/a>\u00a0<\/span>et son \u00e9cosyst\u00e8me, en entra\u00eenant
\nl’apparition de maladies inconnues jusqu’alors dans certaines zones
\ng\u00e9ographiques, des<\/span>\u00a0<\/span>migrations<\/span><\/a>\u00a0<\/span>de certaines esp\u00e8ces, voire leur<\/span>\u00a0<\/span>extinction<\/span><\/a>\u00a0<\/span>si elles ne peuvent s’<\/span>adapter<\/span><\/a>\u00a0<\/span>\u00e0 leur nouvel<\/span>\u00a0<\/span>environnement biophysique<\/span><\/a>.<\/span><\/p>\n

C’est apr\u00e8s la<\/span>\u00a0<\/span>Seconde Guerre mondiale<\/span><\/a>\u00a0<\/span>qu’une prise de conscience des r\u00e9percussions des activit\u00e9s humaines sur
\nl’environnement voit le jour, parall\u00e8lement \u00e0 la naissance de l’<\/span>\u00e9cologisme<\/span><\/a>\u00a0<\/span>et de l’<\/span>\u00e9cologie<\/span><\/a>. Les pr\u00e9occupations environnementales conduisent les gouvernements \u00e0
\nprendre des mesures pour limiter l’<\/span>empreinte \u00e9cologique<\/span><\/a>\u00a0<\/span>des populations humaines et pour contrer des activit\u00e9s humaines
\ncontaminantes.<\/span><\/p>\n
