Fiche à imprimer : Where have the stars gone? La pollution lumineuse (2nde)

Anglais	Français
light pollution	la pollution lumineuse
the Milky Way	la Voie lactée
a dark sky reserve	une réserve de ciel étoilé
Artificial light confuses nocturnal animals.	La lumière artificielle désoriente les animaux nocturnes.
It has become harder to see the stars.	Il est devenu plus difficile de voir les étoiles.
wasted energy	de l'énergie gaspillée

Dans les villes, l'éclairage artificiel est si fort qu'on ne voit presque plus les étoiles : on estime qu'une grande partie de la population européenne ne peut plus voir la Voie lactée depuis chez elle. La pollution lumineuse désoriente les oiseaux migrateurs, les tortues marines et les insectes nocturnes, perturbe notre sommeil et gaspille de l'énergie. Des zones protégées, les dark sky reserves (comme dans le parc d'Exmoor ou au pays de Galles), limitent l'éclairage. Present perfect : It has become harder... We have lost...

Mise en situation : la sortie astronomie

Guide : Welcome to a dark sky reserve. Look up! Can you see that white band?

Bienvenue dans une réserve de ciel étoilé. Levez les yeux ! Vous voyez cette bande blanche ?

Leo : Wow! Is that the Milky Way? I've never seen it before!

Waouh ! C'est la Voie lactée ? Je ne l'ai jamais vue !

Guide : Many people have never seen it. In cities, light pollution has made it invisible.

Beaucoup de gens ne l'ont jamais vue. En ville, la pollution lumineuse l'a rendue invisible.

Mia : Is light pollution bad for animals too?

La pollution lumineuse est mauvaise pour les animaux aussi ?

Guide : Yes. It confuses birds that migrate at night, and baby turtles go towards streetlights instead of the sea.

Oui. Elle désoriente les oiseaux qui migrent la nuit, et les bébés tortues se dirigent vers les lampadaires au lieu de la mer.

Leo : So turning off unnecessary lights would save energy and help nature!

Donc éteindre les lumières inutiles économiserait de l'énergie et aiderait la nature !

À retenir

light pollution, a streetlight, the Milky Way, a star, a dark sky reserve, nocturnal animals, migration, energy.
Present perfect : have never seen, has made, has become ; would save (conditionnel) ; instead of.
