Unicef: #NoFilter, 4 | Ads of the World | Biology resources for South African teachers | Scoop.it

We took pictures of Vietnamese children living along polluted rivers. Then we developed the pictures the old way, in water and a dark room. But we developed it in the polluted water of the river of their neighborhood. This is the result. If impure water does this to a picture, imagine what it does to the health and well being of a child. Clean water matters.

Andrew van Zyl's insight:

This was quite thought-provoking. You might want to put the images up in your classroom-you can find the rest below this image.
