Volunteers collect rubbish during the annual "Big Bottle Count"

Plastic bottles lie washed up on the bank of the River Thames before the start of the annual "Big Bottle Count", run by the organisations Thames21 and #OneLess, by the Queen Caroline Draw Dock in London, Wednesday, Sept. 19, 2018. Volunteers are collecting rubbish from along the River Thames and counting the single-use plastic bottles, to gauge if the plastic waste problem is getting better or worse. [Photo: AP]
