There's a huge hypocrisy in wanting others to pollute less, yet still have a lifestyle that pollutes, but just less than those polluting the most.
I personally won't criticize people who take flights to go on vacation (I don't but I accept those who do). But I'll be pointing out the hypocrisy of those who take flights to go on vacation and yet want to micro-manage how others should live their lives so that they'd be "polluting less".
Recently some infographic made the round for it showed the act a human can take and the pollution it generates. The reason it circulated a lot is because the first item was highly controversial: "having a kid". And yet there's lots of truth in that.
For example my wife and I we got one kid and my wife is now in her forties and we won't have a second one. And I'll never ever take a single lesson about pollution from anyone who had two kids or more.
I'm the one who don't fly. I'm the one who only had one kid. And I'm not criticizing other people's lifestyle and choices. But if you open your mouth, I'll point out the hypocrite you are if you either fly or had two kids or more.
