A plastic bag rests over a bush in the Bolivian Altiplano plateau. Photographer Eduardo Leal found this to be common in the region.
Leal got low to take photos of the bushes to make them look like trees. "Turning little bushes into big trees was to show the size of the problem," he said.
What makes Leal's photos so revealing is the fact that there are no people around. It shows that while the bags may have been discarded long ago, they never completely disappear.
The photos were all shot at sunset. "I tried to create beauty, because maybe with beauty people will look at (the photos) for more time and maybe they will question themselves," Leal said.
