Greenpeace volunteers head from Sydney’s Botany Bay up the Cooks River to pick up rubbish. The initiative is driven by the Sydney Greenpeace Local Group and takes place on the first Sunday of each month at various locations around Sydney. Most of the rubbish collected consisted of plastic bags, plastic beverage containers and other plastics.<\/figcaption><\/figure>\n\n
