Limits to tourism

Interesting piece on Reuters environmental blog suggesting limiting visitor numbers to Galapagos and Antarctica to protect wildlife. Besides the link with Darwin that's much in the news on the 200th anniversary of his birth, I connect to this because (i) we have a brand new OU course on Environmental Responsibility starting in May and eco-tourism is the topic of the final project so our students will be looking for such accounts that connect ethics, policy and action and (ii) because I've just been probably as close as I'm going to get to Antarctica in visiting Patagonia so am aware of the huge importance of tourism in local economies and the challenge of managing this activity in ways that are sustainable both ecologically and socially.
