Tourism and the Moral Maze

Last week's Moral Maze programme on BBC Radio 4 had a disappointly poor quality of debate, so I turned it off before the end and might have missed some gems. The debate seemed to consist of witnesses who were concerned about the environmental and economic impact of mass tourism being branded as killjoys, and the witnesses desperately trying to show that they weren't.

What seemed to me missing was the (to me) obvious truth that "too much of a good thing" can be applied to individuals. The panel seemed to be saying that avoiding too much tourism would be unfair because it would mean that only the rich could travel. But another way to avoid too much tourism would be to enable everyone to travel but to do it less often. So instead of 1/10 of the population taking two high-impact holidays a year, why don't we work towards enabling the whole population to take a high-impact holiday every five years?
