Plastic Pollution and The Ocean Cleanup

The video discusses the threat of plastic pollution in oceans, focusing on the Great Pacific Garbage Patch. The Ocean Cleanup conducted extensive research, including the Mega Expedition and aerial surveys, to measure the extent of plastic pollution. The findings reveal a massive accumulation of plastic, with 1.8 trillion pieces and a total mass of 80,000 tons. The research highlights the increasing pollution and the need for cleanup efforts, set to begin in 2018.
