From the link:
“By identifying and tracking patterns of pollution over time, stakeholders will also be able to focus resources and policies to improve prevention.”
I don’t know how but I guess they don’t know which rivers & ports or what countries the pollution is coming from? They’ll need donations & mariners to send them pictures of the floating trash so they can go to those places to get those governments to change their policies & law enforcement concerning litter? Sounds like one of those scam shakedown organizations that tried to sell carbon credits. Good luck to them.
