Countries with ties to Antarctica have adopted US proposals to limit tourism in the region, in a bid to protect the fragile ecosystem of the continent.Parties to the Antarctic Treaty agreed to limit the size of cruise ships and the number of tourists taken ashore at a meeting in the US city of Baltimore. Limiting tourism has taken on urgency due to a surge in visits and a number of cruise ship accidents. Antarctic visits have risen from 6,700 in 1992-93 to over 45,000 last season.
