Would you pick up litter if your life depended on it? Around the world, companies and governments are trying to incentivise people to pick up litter and recycle their waste. In Nigeria, we visit the tech start-up which encourages people to pick rubbish up off the street – and then swaps the plastic bottles, cartons and metals they collect for potentially life-saving healthcare. And in Turkey, we meet the mayor on a mission to get his residents recycling, by exchanging their household waste for points that earn them money.
