I'm pretty sure I'm not currently being killed. Also life expectancy is still rising and people are getting older then ever. Doesn't check out.

"A handful of people"?!

Come on, about 10% of greenhouse gas emissions come from flying. Amd that's done almost exclusively by the common folks, not the tiny minority. A kilometre by train causes 99 % less (electric) or about 70 % less (diesel) emissions per kilometre than an airplane does, and is a viable way to travel, but people still fly. Because they prefer being assholes and kil their own children if not doing.so would inconvenience them evem just a little.

Similarly, feeding one person with red mean causes about as much greenhouse gas emissions as feeding 10 vegetarians. No need to go full vegan, but decreasing consumption of meat would make another 10 to 20 %. And then there are the private cars, something in the ballpark of 5 %.

About a quarter of oyr greenhouse gas emissions are caused.by things that.are completely unnecessary. Yeah, at the moment all of those three would be inconveniences, but only because others don't do the same. High-speed railways take less resources to operate per passenger and reach about half the speed of an airplane (if you take time spent at airports into account), but the service is unusably.bad because everyone flies. And all the nice ready-made food is meat-based, because the other stuff doesn't have enough markets and is therefore too expensive, thus staying on the shelves And also, public transit is not comfortable because it isn't used by the rich, so there's no motivation to.keep it at the level it has in Switzerland, where even the richest typically commute by train.

The greenhouse gas emissions.don't need to be brought to zero fot us to.survive. We common.folk have the capacity to lower them by almost a fifth, which makes a huge difference in pur future Yeah, the remaining 80-ish % is in the hands of the few, but in this case even our 20 % is relevant enough that your excuse is appalling.
