I am glad you took the time to write this, because it highlights an issue, showing how and why not enough people care yet, to try to change things for the better.
The issue of global climate catastrophe, and actually even war, is that we are doing something unsustainable as a species.
For the species to change, the individual has to change.
If the individual won't change then the species will perish.
So exactly the opposite of what you say is true.
Disaster and war, is happening all over the world, because too many think like you.
What you are saying is typical selfishness, which is actually at the heart of colonialism and even Nazism. which originated in, an took your country previously, because folk had exactly the same attitude as you. If it isn't happening to you personally, then you think best ignore it, Niemoler said it perfectly.
If you don't change, then you are the one guaranteeing, and causing disaster.
The Gretas will keep multiplying and needling you with this until you are shamed into doing the right thing dude :)
