Why The Ocean Cleanup Hasn't Solved the Plastic Pollution Crisis

Why The Ocean Cleanup Hasn't Solved the Plastic Pollution Crisis

The Ocean Cleanup's 2019 test caught hundreds of marine animals, as marine ecologist Dr. Rebecca Helm warned. Experts say the nonprofit's approach, based on a misunderstanding of the garbage patch, has failed to make a dent and may harm ecosystems. It has pivoted to river interceptors, but critics remain skeptical.

This ecosystem is ecologically important to species that we do care about. We can’t just go disrupting it in the name of conservation and imagine that everything is OK and that you’re doing a good thing.

    They may not have solved the problem, but at least they are doing something about it. In my opinion, that's better than doing nothing at all. I've seen firsthand how their solutions have been implemented and have had a positive impact on the environment. How often do we hear promises from NGOs or government entities claiming they will solve humanitarian issues such as housing shortages or hunger, only to fail miserably while spending billions of dollars in the process? Meanwhile, others grow rich from government tenders and contracts at the expense of the unfortunate beneficiaries.

    The title of the article is kind of technically correct but still misleading.

    It is true that The Ocean Cleanup "we're going to trawl the ocean for plastic" approach isn't working terribly well.

    But they did pivot to stopping trash from washing out of rivers and into the ocean which is working. Stopping the mess from growing is also a very good thing.

    This seems like some combination of the enemy of good is perfect and also sour grapes that someone else is doing the thing.

    I'm not arrogant enough to think I know more about this than an expert who's devoted their life to ocean research, but the article itself comes across as a list of grievances against the Ocean Cleanup project rather than an objective review - mostly due to emotionally charged language like "apparently killing enormous numbers of marine organisms" and "out there spewing diesel fumes from a ship that cost $100,000 a day"

    It took a bit of digging, but it looks like around 80% of the plastic the Ocean Cleanup has captured comes from rivers - while the article focuses mostly on criticizing the open ocean catch. It would be interesting to see what is the budget split between the two methods, but I couldn't easily find it.

    It makes sense to me that removal requiring infrastructure will be more costly than unpaid volunteers on land. It is NOT clear to me if that means the infrastructure solution is not worth pursuing in parallel. It does seem the open ocean catch is ineffective compared to the river capture, and I can understand that argument. Not so clear to me if / why river capture should be scrapped in favor of the volunteer beach cleanup, as the article seems to imply. Intuitively, pursuing both would makes more sense. Again, this would be a very interesting analysis to see.

    > Every organization contributing to the International Coastal Cleanup does things a little differently, but for every $2 invested Ocean Conservancy can remove a pound of trash from the environment and invest in scientific research and upstream policy solutions to prevent plastics from being produced and/or entering our ocean in the first place

    Okay so the article’s prime version costs $2/lb of trash removal. Looking at a random report from a couple of years ago they did 11 m pounds[0]/year

    Let’s look at the next paragraph to see how the non-profit they’re comparing against did:

    > As of this writing, The Ocean Cleanup reports it has removed 117.3 million pounds of waste from the ocean and (mostly) rivers. The nonprofit spent more than $72 million across its 2022-2024 fiscal years, according to tax filings.

    Okay, so the competitor is $0.6/lb. I mean that sounds great. The whole article is like a price comparison against a competitor where they say “the other guys are more efficient, cheaper and we cost 3 times as much”.

    Honestly, this kind of Fundamentalist Church of Environmental Science vs Seventh Day Fundamentalist Church of Environmental Science stuff is always pitched as such high stakes and it’s always some aggrieved party upset because they “don’t want to live in a world where someone else saves the Earth better than [they] do”.

    "The river interceptor design was clearly based on existing solutions" like Mr. Trash Wheel, Dr. Richards says. "Rather than work with the organizations who had successfully been removing trash from rivers for years, they ‘reinvented’ a similar design, at a much higher cost, and claimed to be innovators."
