The Mekong River flows through six countries in Asia, contributing to much of the plastic in the oceans. Drones are being used to take photos of the plastic found in the river, giving them a geo-tag to provide scientists with data on plastic hotspots.
Much of the plastic that originates from the Mekong River ends up drifting onto Australian shores and causes danger to the wildlife in the area. The scientists are now turning to technology, specifically drones to help fix the issue and reduce the amount of plastic that ends up in the ocean.
