From Lachlan Jones, Brisbane, Australia
In one part of your illuminating article on a net-zero life, you mention the fictional Isla planning a holiday that avoids the “moral opprobrium” of long-haul flights in favour of a train tour in Norway (4 September, p 34). While I agree that travelling by train is preferable to flying within Europe, I can’t help but wonder about the future of nature reserves in Africa, South-East Asia or South America if tourists stopped visiting because of aviation emissions.
