The disregard some people have for the environment is an epidemic. Hate to say it but these people are slobs with no respect for themselves and even less respect for a public resource. While I appreciate the efforts of the people in the video cleaning the surface level of the river, the amount of trash collected in nothing short of obscene. 40,000 lbs a month on average! Some of the debris is fallen trees and branches but the amount of plastic and consumer trash is incredible. No wonder the world's ocean's are turning into cesspools. Bitter sweet story. As the countries / world's population continues to increase, this problem becomes exponentially worse.
