This might be a stretch, but it always reminds me of Craig Ferguson’s rant on ‘The deification of youth’: https://youtu.be/UKUZ42T9diU Edit: (*Scottish!): Ironically, he’s an old Irish man :p

Craig Ferguson is not Irish.

Oh man, I thought they were all the same up there.

The Ocean Cleanup project started somewhat like this. They made prototypes and extensive testing, and concluded honestly that cleaning the ocean isn't doable, so they turned to cleaning up the source of most oceanic plastic: rivers. Their river cleaning boat is completely different from their initial idea, but it works well. Ideas are cheap; execution is hard...

This. It seems to me that every few years there's a new "brilliant" idea by an unlikely "inventor" that promises to solve every pollution problem in the ocean forever. But then it becomes clear that the brilliant idea on paper is impossible in practice, on scale, so it never comes down to anything other than wishful CGI.

The media around the topic is too focused on heroics, as if this is a puzzle with a nifty solution that only someone thinking outside of the box can come up with. Reality is less elegant.

When I saw the interceptor it reminded me a lot to this much older project.

While that’s true it’s also important not to discourage youngsters from having ideas. It’s all too common that us older, perhaps more jaded, folk will lecture others with comments like “ideas are cheap” but those ideas come from people with fresh enthusiasm to solve those problems and sometimes that enthusiasm does translate to execution.

So while I do agree with your point, we should still be encouraging ideas.

The article hints that the filtration process could happen in washing machines, even further upstream (so to speak)

Oh I'm all for radical ideas, it's mostly this sort of hollow media coverage that annoys me.

Probably a good idea to filter the "output", but I'd imagine this would be interesting for a lot of people to filter tap water as it comes in as well, combined with whatever other filters you may already have.

Is it impossible? Or is it because our poor millitary couldn't spare $2Bil to execute on these ideas? Or the global military budget by all countries couldn't spare $20bil to execute?

I think it's very important to distinguish which things are technically not possible, vs we simply chose that our murder machines are more useful in the short term.

Or just a coarse metal catcher in front of the estuaries of the most polluted rivers https://www.weforum.org/agenda/2018/06/90-of-plastic-polluti...

They mean to say "90% of the plastic in the ocean that comes from rivers comes from just 10 rivers". https://factcheck.afp.com/widely-cited-study-did-not-show-95... "It estimated that 88 to 95 percent of the plastic transported by 1,350 large rivers around the world — referred to by scientists as riverine waste — comes from only 10 rivers, all of which are in Asia and Africa. The study does not attempt to compare the…

That "once again, Canada is not the problem" line in the viral post is missing the point so, so badly.

Like, yeah, lots of industrial waste comes from developing countries where the major production centers are, mostly in Asia. But the people sharing that image should ask themselves where those products go after they're made. A huge amount of that production is for the richer Western countries, and that does make it your responsibility if you live there.

This is how industrialized countries lower their CO2 output as well: just outsource it other countries. Under the Paris Agreement, countries are only held responsible for emissions that occur within its borders. It's just another way for the greatest consumers to be able to shrug and say "not our fault".
