Scientists warn of tourism threat to Antarctica

SYDNEY: Antarctic scientists warned that a surge in tourists visiting the frozen continent was threatening its fragile environment and called for better protection.

Tourist numbers have exploded from less than 5,000 in 1990 to about 40,000 a year, according to industry figures, and most people go to the fragmented ice-free areas that make up less than 1% of Antarctica.

A growing number of research facilities are also being built, along with associated roads, fuel depots and runways, in the tiny ice-free zones.

It is these areas which contain most of the continent’s wildlife and plants, yet they are among the planet’s least-protected, said a study led by the Australian government-funded National Environmental Research Programme (NERP) and the Austra­lian Antarctic Division.

“Many people think that Antarc­tica is well protected from threats to its biodiversity because it’s isolated and no one lives there,” said Justine Shaw from the NERP in the study published in the journal PLoS Biology.

“However, we show that there are threats to Antarctic biodiversity.

“Most of Antarctica is covered in ice, with less than one percent permanently ice-free,” she added.

“Only 1.5% of this ice-free area belongs to Antarctic Specially Protected Areas under the Antarctic Treaty System, yet ice-free land is where the majority of biodiversity occurs.”

Five of the distinct ice-free eco-regions have no protection at all while all 55 of the continent’s protected areas are close to sites of human activity.

Steven Chown, from Monash University’s School of Biological Sciences, another collaborator in the study, said the ice-free areas contain very simple ecosystems due to Antarctica’s low species diversity.

This makes its native wildlife and plants extremely vulnerable to invasion by outside species, which can be introduced by human activity.

“Antarctica has been invaded by plants and animals, mostly grasses and insects, from other continents,” he said.

“The very real current and future threats from invasions are typically located close to protected areas.

“Such threats to protected areas from invasive species have been demonstrated elsewhere in the world, and we find that Antarctica is, unfortunately, no exception.”

The study said the current level of protection was “inadequate by any measure” with Shaw saying more was needed to guard against the threat posed by the booming tourism industry. — AFP
