Yeah I'm all for fighting climate change but air travel should be excepted until there's battery-powered options available. We can't go back to the dark ages of travel. And especially internationally in Europe the rail network is shit and has way too little capacity. There's almost no good international high speed rail. It's only in countries that invested in it locally like Germany, France and Spain.
Completely agree with this. Anyway shifting all our trips to train travel is not the answer. The answer, which I do prefer, is not travelling at all when avoidable. I only ever travel for holidays and funerals. Never on business. All business can be conducted on conference calls.
But for personal use I don't think travelling less is an option. I hate travel but it's important to see family too. We can't just roll the world back to where a different continent was unreachable.
