so long as it is done responsibly
why should Antartica be off limits to visitors
I can see it being off limits to development but not necesarally visitors
How are you going to get there? You will need an icebreaker and some twin engined Otter planes and the support of the authorities of one of the countries which has claims to the place. Which is normally not given, due to extreme conditions and remoteness.
Icant, there are already expeditions to Antarctica, and these should be reduced, after a saw a David Suzuki documentary.
cons , its just a load of ice
