This is just plain bad reasoning, for obvious reasons.
It is not “hypersensitive” to care about the CO2 impact of air travel. In fact it is a large blind spot for many otherwise progressive-minded people. These travel shows genuinely espouse progressive principles of learning from other cultures and yet almost never is there any mention of the significant CO2 impact. All the little things you might do throughout the year to lower your impact and get to where we need to be in 12 years are easily wiped out by just one plane trip. It’s good to talk about it.
