An extraordinary video surfaced at the beginning of March. British diver Rich Horner posted footage from a recent dive in waters off Bali, Indonesia. The video shows him swimming through a thick soup of plastic waste that includes wrappers, bags and other assorted multi-colored packaging.
Horner's video highlights just how serious and pressing the issue of plastic waste is. For example, Europeans produce 25 million tons of plastic waste per year, according to the European Commission. Staggeringly, less than 30 percent of this is collected for recycling.
Here, CNBC's "Sustainable Energy" looks at a selection of images that highlight the impact of plastic pollution on our planet.

The issue of plastic washing up on beaches is an incredibly serious one, although efforts are underway to tackle the issue.
In the U.K, for example, a levy on single use plastic bags has had a significant impact.
In November 2016, the Marine Conservation Society announced that the number of plastic bags found on U.K. beaches had fallen by almost half in one year. The organization said that the 5 pence (7 cent) charge had been a major factor in the drop.
