I am pretty sure land use for all those tracks, elevated rail beds, tunnels and bridges, stations is FAR higher than what the planes use.

Single plastic usage is such a red herring...every time you load up your car with gas, you put in 15 gallons, that is ~50 kilograms. A plastic straw is 0.4 grams, 125,000 plastic straws to amount to the same hydrocarbon footprint. This is a very rough math, but you get the idea. You can compensate for all your life consumption of straws and forks by not filling up once. Plates are heavier, but still marginal compared to everything else.

Another one: plastic grocery bags are 5 grams, that means one tank of gas is like 12000 grocery bags.

You could say: but at least use less single use plastic! Have you considered the alternatives? Would stainless plates weigh much more on a plane, and induce a higher CO2? Would food non-wrapped in plastic spoil more? (We throw away about 50% of all fruits and vegetables anyway).

GHG is a tough problem. Focusing on some token issues like plastic straws and plane travel for ordinary people does not solve it, it only makes it harder for people to accept it.

It might be a token problem but I think it's important to put this on the map for people to even realize it's a problem.

Also, trains (in large parts of Europe anyway) run on electricity only of which a significant chunk is from nuclear power, which doesn't emit anywhere near as much CO2 to move as many people as a plane would.

And the noise. trains are so quiet compared to planes.

The problem is that people have a limited amount of things they can care for. You bombard them with plastic straws bans, grocery bag bans, 100% gas taxes, diesel poisons, shaming flying and you amount to maybe 1% reduction in GHG.

Then when it come to bigger hitters, like industry, building insulation, agriculture etc. you will get exhausted and poorer people that just can't take it anymore. And then you end up with people thinking this is all so futile and so scared of the future that they don't want to even have kids anymore.
