Around the world, rubbish is collecting in our gutters and waterways, with millions of tonnes being washed out to sea every year. As the soup of ocean debris kills and injures millions of marine animals, we look at two projects trying to make a dent in the problem. We discover a Greek project which has enlisted thousands of fishermen around the Mediterranean to collect rubbish from their nets, rather than throw it back. They then sort it and hand it over for recycling when they return to port. We then travel to Accra in Ghana where a group of volunteers called the Buz Stop Boys are busy clearing the streets of rubbish. They hope their noisy grassroots movement will inspire others to take responsibility for public places and stop rubbish being washed out to sea. And we hear from Teddy, our youngest problem fixer yet. The six year old from the UK has stopped thousands of sweets tubs from going to landfill, proving you're never too young to fix the world.
