MailOnline takes a look at the technologies to remove 199 million tonnes of plastic littering oceans

Plastic waste is being discovered in increasingly remote locations around the world, from fresh Antarctic snow to the mountain air above the Pyrenees. According to the World Economic Forum, between 75 and 199 million tons of plastic are currently in our oceans. This ranges from large floating debris to microplastics, which form as the bigger pieces of waste break down. As a result, scientists and engineers are working hard to find new solutions to the global problem of plastic pollution. These include aquatic drones that can be programmed to scoop up floating debris from the surface of rivers, and buggies that use artificial intelligence (AI) to search for and pick up litter for use on beaches.
