Agar is a mixture of polysaccharides, polymers of [HCOH], so is eminently biodegradable. Plenty of marine creatures graze on seagrass, where it forms the cell walls. When re-formed as a commercial plastic, its biodegradability would depend on the surface area to mass ratio and its crackability, discussed above.

"Budget" is being pushed at us as a concept that must not be questioned. The concept relies on the idea that every developing nation has an equal right to pollute as the developed nations already have done. However the concept, I might say "conceit", is pious nonsense. Yes, the developed nations have emitted and poisoned the greenhouse. However we have done so in ignorance of the consequence of our actions. Now that science is telling us that we are committing damage, all of us who emit – developed and undeveloped – are committing damage in full knowledge of the lethal consequences of our actions. No one has a right to cause the deaths of others. No one has a right to pollute. And no one should have a right to emit at all. A budget is out of the question.

Arctic sea ice loaded with microplastics Marlowe Hood 2019 Aug 16 Phys.org m.phys.org/news/2019-08-arctic-sea-ice-microplastics.htmlMore plastic in the ice than in the water where the sample was taken, but that's far removed from the origin of the ice. Furthermore it appears that they didn't try to determine the number of plastic particles by size nor the lower size sensing limit of their instruments.

More plastic in the ice than in the water where the sample was taken If the plastic of certain particles is buoyant then they will tend to accumulate at the surface, with a tapering distribution stirred downward by wave action. When a cold wind freezes the topmost water, the stirring decreases, buoyant particles rise and the growing ice would entrain a higher proportion of plastic than in the water below. Eventually, when the ice is melting from below, the scavenging biota that live on its base would accumulate the plastic, to be eaten by the fish that graze on the algae etc there.
