The most positive climate impact you can have is not having a kid, not having a car and not flying, in that order.
I do not have any kids, that’s why I don’t have to worry about your attitudes. But it is not a single thing we have to change, it all has to change.
Food is responsible for approximately 26% of global GHG emissions.
Where I live meat production goes down already, but you not having a kid will not change anything because you not getting laid was so predictable that every climate model considered it already.
E: Nice touch that you did not refute that meat is bad for your health and now focus on “but there are other things too”
It is always just a black and white thing without seeing the good things. Just like this kid, he could have maybe killed more and has restrained himself really hard. If we blame him for what he did he will just kill more the next time.
