The best solution to climate change is to kill shit like private jets and yachts.

I severely doubt those emissions are anything but negligible because there are so few yachts and jets.

Edit: Yeah, just downvoting is cheap, so here's just a single statistic for you: https://ourworldindata.org/global-aviation-emissions

Total aviation is responsible for about 2.5% of worldwide carbon emissions. That's all air travel, private jets included. While it's obviously very popular to focus on the luxuries of the rich, it just won't be effective to focus on those when fighting climate change, let alone being a solution as you claimed.
