Nigeria's Lagos state will start implementing a ban on Styrofoam and other single-use plastics. The State's environment commissioner told the BBC that non-biodegradable plastics were a major pollution problem, and were clogging drains. State officials say they'll use a dormant 2009 law to fine or jail culprits. Lagos is one of Africa's most populous cities. International experts estimate Nigeria generates 2.5 million tonnes of plastic waste annually.
