Too lazy to photoshop, but the average dutch household produces 2.2 tons of CO2e for heating and 0.8 tons in electricity. The average household is 2.1 people, so call it 1 ton for heating, and .4 tons for electricity.
So going completely off-grid (VERY hard) will place somewhere around equal to the "Buying green energy" bar (duh...).
Just solar panels will rank around "Replace car with electric".
Looking at a couple of sites shows a vegetarian diet produces something like 4-4.5 tons of Co2e a year, and vegan 3-3.5 tons. A "normal" diet ranges between 7 and 10 tons, probably depending on your definition of normal. Other sites list 1.5, 1.7 and 3.5 tons for vegan/vegetarian/regular.
The big gain seems to be dropping meat, with everything else* adding another 10% or so savings. But 1 tons of CO2 is roughly equivalent to driving your mid-sized (european mid-sized, that is) car for 5000km.
*These numbers are purely diet. I can't seem to find anything for a whole lifestyle.
Not having children is a pretty certain method of not having grandchildren though. You can compared the local/national/worldwide average reproduction odds against the certainty of not having (great)grandchildren.
The Doolittle raid is the perfect example of a PR move, because it was insanely expensive and did very little. It cost 16 planes and their crews, and took very expensive ships out of the running for months. BUT despite doing basically no damage, made Japan bring 2 carriers away from Midway to take a couple of tiny islands to prevent bomber bases being built on them.
As far as we know, this basically took some RHIBs and troops on foot. Way less than the Doolittle Raid. Unfortunately it's likely we'll never know the effect this had, or how many of these raids take place.
This is really only a raid, Ukraine has no ability to supply troops by sea, nor the ability to even land enough troops to hold territory.
But the fact that they did this means that Russian "rear" area security is absolute shit, and they have the option to improve that (taking forces from reserves or the fromt) or suffer more rear area raids.
Traditional sails are also fragile, complex, expensive and very labour intensive even with electric winches. A fully rigged ship is exceptionally complicated and knowing how to work one takes huge skill and knowledge, and that's not even mentioning what to do when something goes wrong. And of course, it's much slower as well.
I've been woke moralizing for free, like some kind of chump. No more I say, I'll stop doing it for free right now! I demand fair pay and equa... Damn it.
