WHAT IT SHOWS: Alaba Market, Lagos Nigeria. Many of the computers here are second hand and shipped from Asia, the USA or Europe for reuse. The small shop dealers buy electronics from the containers and are very good at repairing the goods for sale. When material has no value is it sent to nearby dumps, and young men look for parts or wire that they recycle for the metals. However, much toxic material ends up in these dumps in Nigeria.
