Im not surprised. We have pretty good waste management systems. Almost all of our trash ends up in landfills where it is compacted and covered each day. This prevents it from get into the ocean. However, many 3rd world countries have open dump sites instead of landfills. This allows the waste to wash into rivers and deposit into the ocean. Here is a video showing the magnitude of these open dump sites in some of these countries. From this it is easy to see just how much trash can wash into the ocean.

Possibly. More than possible, the great filter can certainly be some entropy problem where exponential complexity is accompanied by more than exponential energy needs, which eventually cannot be sourced locally.

Certainly most civilizational collapses could be described in such a manner, because sufficiently directed energy could readily solve most problems.

The US outsources those trash to these top 10 countries. The Philippines, being 10% of China's population, produces 5 times more plastic waste according to these stats.

For every plastic bottle wasted a day by a Chinese citizen, a Filipino has to waste 50 bottles to reach those numbers.

That's unrealistic.

The thing is, there were such products before rampant plastic production. It’s just been crafted to make single use plastics the cheapest type of packaging. Then the producers blame the consumers for where the waste ends up. Not to mention there’s a hefty lobbying sector fighting to keep single use plastic production high because it means more profits for petrochemical companies.

The easiest way to dispose of orbiting bodies is to crash them into Earth. Most sats are quite small and unless you're dropping the ISS, they burn up in the atmosphere.

Future sats may use drag sails to slowly pull it down. https://www.space.com/esa-drag-sail-prototype-adeo-unfurls

And regulation is already happening, the FCC has introduced the 5-year plan. https://www.nasa.gov/smallsat-institute/sst-soa/deorbit-systems https://www.fcc.gov/document/fcc-adopts-new-5-year-rule-deorbiting-satellites

Removing existing debris will ultimately mean slowing them down, to drag them to earth. A likely candidate is using lasers. https://phys.org/news/2021-04-laser-sky-space-debris.html But other concepts are being developed. https://www.npr.org/sections/thetwo-way/2016/12/09/505020386/japan-sends-long-electric-whip-into-orbit-to-tame-space-junk https://www.npr.org/2021/03/21/979815691/new-effort-to-clean-up-space-junk-prepares-to-launch https://www.cnn.com/2018/09/30/business/space-debris-capture/index.html
