Thousands of discarded computers from western Europe and the US arrive in the ports of west Africa every day, ending up in massive toxic dumps where children burn and pull them apart to extract metals for cash. Some are shipped as "donations" but many of them don't work. And the volumes are large: according to the video, something like half a million waste PCs arrive in Lagos every month. Apart from anything else, this isn't helping legitimate supplier of second-hand computers to the developing world, such as Computer Aid International.
