50 immagini che dimostrano gli effetti devastanti del cambiamento climatico
(secondo la Nasa)

Il cambiamento climatico è uno dei fattori che più di tutti sta incidendo sul nostro pianeta, che, negli ultimi anni – in un arco di tempo brevissimo – ha rimodellato interi paesaggi, facendone addirittura sparire altri.
La Nasa ha pubblicato sul suo sito una serie di foto che denunciano quanto sta avvenendo, cercando così di sensibilizzare l’opinione dei cittadini e non solo. Il sito Images of Changes mostra infatti 309 fotografie del “prima e dopo” di tantissimi luoghi che sono stati profondamente modificati dall’intervento umano e dal riscaldamento globale.
Rilievi satellitari, ma anche fotografie d’epoca, che ci permettono di vedere quanto il globo terracqueo sia profondamente mutato a causa dello sconsiderato intervento dell’uomo sulla natura.
