Cost vs. benefit... You and GP deem it as pointless, but educating people about climate change and getting governments to align is worth the net cost. The only way you can get world governments on track with the program is to fly delegates out to these places. Simply existing contributes to GW and environmental impact, but that's a cost I think we should all be willing to accept. Pointing out hypocrisy where none exists makes you and the OP look foolish. That's why you you got downvoted.
