Simply a matter of focusing on making the improvements where solutions are available. Moaning about people using air travel right now when 1. there are limited other options, and 2. it is not anywhere near the most significant issue is a waste of time and just being deployed as baseless ad hominem
Australia is in a position to do more, and it's Government is actively promoting fossil fuels where alternatives are available and making false arguments to justify their position. Totally different situation.
