Plastic is polyethylene, which is a long chain of repeating ethylene molecules. To make it biodegradable they just put starch molecules in the chain every so often.

A lot of plastic is polyethylene, but nowhere near all of it. There are plenty of polymers that can break down naturally, mostly polyesters like PLA (which breaks down into lactic acid, the same naturally produced compound that causes muscle soreness after workouts). A lot of work is being put into making PLA have better material properties so it can replace more of the conventional plastics. It's also generally made from corn and can be pretty close to carbon-neutral. So long story short some biodegradable plastics are worse, but some have legitimate applications and are genuinely better than current options.

Interestingly, a Mexican cartel did something very similar for their comms network about 13 years ago (source)

Soldiers seized 167 antennas, more than 150 repeaters and thousands of cellphones and radios that operated on the system. Some of the remote antennas and relay stations were powered with solar panels.

So he typically advertises for VPNs? I don't understand.

He "typically" discusses interesting places/people. In the first 5 or so seconds of the video he discusses a fictitious person and how they "weren't protected from viruses, but you could be with a VPN". So he transitions from his typical video style to a VPN ad to then highlight all of the things wrong with VPN ads.

The opening scene is a parody of his typical videos (which are typically about places/people) transitioning into a VPN ad segment. The fact that it isn't about a real person means that it is not in fact from one of his real videos. If you watch the opening scene and read the pinned comment on the video my reply might make more sense.

This is inaccurate, read the pinned comment on the video where he points out that the opening scene is entirely made up and isn't about a real person.

Btw your 20% figure includes those at Level 1 literacy, only 8% are below level 1 (from your source)

I will say that I've been able to bring 3-4 grocery bags onto a bus, which is enough to last me around 2 weeks. I've done this fairly consistently (basically whenever it's too cold/snowy to bike) for the last couple years. It might not be possible for a family without more than one person making the trip, but for an individual it can definitely work.

Second, power lines face an especially onerous permitting process. A new transmission project must generally seek approval from every city, county, and state that it passes through. A new natural-gas pipeline, by comparison, only needs to be approved by FERC.

Ridiculous. Should be the other way around if anything.

The critical assumption here is that it is easy to make plastic from "carbon, nitrogen, and oxygen". While those are the primary atoms in plastics, actual polymerization reactions (to form plastic) require them to have specific reactive functional groups. The most common ones are alkenes (polyethylene, polypropylene, polystyrene, PVC, Teflon), epoxides (epoxy), or amines and carboxyl groups (the 2 monomers of nylon). While some compounds with these functional groups exist in nature, they are rare and polymers based on them do not have the full range of properties that conventional polymers do. There is a lot of active work in this field, but even once these polymers are perfected it will likely require quite a bit of chemistry/engineering knowledge to produce thm safely and without huge quantities of waste. The only practical way to get large quantities of the major synthetic polymers is as a by-product of oil refinement (they are in such low concentration in oil that it would be infeasible to refine oil just for them), and again there is the safety concern of bootstrapping it.
