The environment: a pressing subject to which the world of photography is paying more and more attention. The photographers have addressed the theme with very different approaches. On the one hand, the investigation and the denouncement of the consequences, often dramatic and irreversible, of climate changes and unsustainable growth that has destroyed habitats and ecosystems and endangered several species. On the other, the search for the beauty of nature and the celebration of it. As stated by Joe Sartore, one of the most committed photographers on the environmental front, photography is a very powerful tool, “capable of showing environmental problems as nothing else can and it can bring people to worry about it “.
