>> 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.

The alternative is not "doing nothing at all." It's spending the money effectively and in ways that don't kill marine life. TFA gives an example near the end:

"So if we can’t scoop all the plastic trash out of the ocean without killing large numbers of marine animals, what can we do instead?

One effective (and cost-effective) solution is the Ocean Conservancy’s International Coastal Cleanup. This amazing program has removed more than 400 million pounds of trash from beaches, where it’s much easier to access than in the middle of the ocean, before it gets swept back to sea. They do this at incredibly low cost, because more than 19 million people around the world have volunteered to help.

“Our total annual budget for all our plastics advocacy work, which includes cleanup, science and policy efforts, is about $6 million,” says Jordana Lewis, director of communications for the Ocean Conservancy Director of Communications. “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.”

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.

Meanwhile Dr. Richards points out that in 2024 Ocean Cleanup’s System 002 “was out there spewing diesel fumes from a ship that cost $100,000 a day, picking up less plastic than a bunch of volunteers on beaches.” (A representative for the Ocean Cleanup told me via email that they are working on improving the cost efficiency of their operations.)"
