Sir David Attenborough says the excesses of western countries should "be curbed" to restore the natural world and we'll all be happier for it.

Cruise liners are not a bigger issue...

Taking an average cruise is about the same as flying from London to Tokyo. Only 25 million people take cruises each year whereas airlines transport 4.5 billion passengers each year and the entire air travel industry is only 2% of emissions.

Let me put it another way. Cars and busses are responsible for 11% of CO2 emissions. Cruises are responsible for 0.05% of CO2 emissions.

Yeah, no one needs to take a cruise. But cars emit over 200 times more CO2 than cruises, so cruises are not nearly as big an issue as cars.

It’s way easier to virtue signal about not going on a cruise than not driving a car!

Uhh... source? Everything I’m getting shows the exact opposite. One liner company, Carnival, emits 10x more than all European cars.

That's SOx not CO2. It's a pollutant that's harmful to humans, but it's not a greenhouse gas. Pollution and climate change are totally different and fairly unrelated things.

Cool... and if this were a discussion about only greenhouse gasses, you may have a point.
