Des nuages de fum\u00e9es \u00e9paisses; des plages englu\u00e9es dans le p\u00e9trole; des rivi\u00e8res rougies par les produits chimiques. Voil\u00e0 des exemples \u00e9vidents de pollution.<\/p>\n<\/div>\n

Mais tous les types de pollution ne sont pas visibles. Des nuages de gaz invisibles peuvent par exemple circuler au-dessus de nos villes ou de nos banlieues. Ils peuvent \u00eatre la cause de probl\u00e8mes d\u2019asthme ou de respiration. Ils peuvent aussi tuer des arbres.<\/p>\n

La connaissance de l\u2019\u00e9tendue des zones affect\u00e9es est aussi un probl\u00e8me. Les vents peuvent transporter les produits polluants sur des milliers de kilom\u00e8tres d\u2019une rive d\u2019un oc\u00e9an \u00e0 l\u2019autre. Les produits chimiques qui s\u2019\u00e9coulent le long des grands fleuves peuvent polluer plusieurs pays avant d\u2019arriver \u00e0 la mer.<\/p>\n

Il faut enfin savoir qui doit \u00eatre accus\u00e9.<\/p>\n

Les satellites sont des armes essentielles dans ce combat toujours renouvel\u00e9 pour assurer la propret\u00e9 de la plan\u00e8te. Des instruments dans l'espace peuvent d\u00e9tecter les gaz dangereux ou les d\u00e9chets chimiques lib\u00e9r\u00e9s par l'industrie, les centrales \u00e9lectriques ou la circulation automobile.<\/p>\n

Les satellites peuvent mettre en \u00e9vidence les sources de pollution, surveiller leur d\u00e9placement dans l'air et voir o\u00f9 elles arrivent. Ils peuvent aussi \u00e9tudier la couleur de l\u2019oc\u00e9an pour d\u00e9tecter des nappes de p\u00e9trole sur la mer, de jour comme de nuit.<\/p>\n

A des centaines de kilom\u00e8tres au-dessus de la terre, ces 'espions du ciel' aident \u00e0 identifier les exportateurs et importateurs de pollution autour du monde.<\/p>","protected":false},"excerpt":{"rendered":"

Clouds of choking smog; beaches coated in oil; rivers turned red by chemicals. All of these are obvious examples of pollution. However, not all types of pollution are easily seen.
