How does tourism in Antarctica affect the wildlife?

How does tourism in Antarctica affect the wildlife?

There has been no conclusive evidence that tourism so far has disturbed breeding patterns of wildlife like penguins. Tour operators have voluntary codes of conduct to minimise the impacts – including not going within five metres of wildlife.

What are the 4 main threats to Antarctica?


  • Climate change. Climate change is the greatest long-term threat to the region.
  • Increased fishing pressure and illegal fishing.
  • Marine pollution. Persistent organic pollutants (POPs) have been measured around Antarctica and detected in wildlife.
  • Invasive species.

Why should tourists not visit Antarctica?

Besides the large carbon footprint that comes with traveling by ship to Antarctica, there are other sources of pollution that a ship produces that are harmful to Antarctica and its inhabitants. Antarctica cruises and expedition ships produce a lot of waste – food waste, carbon waste, sewage waste, and water waste.

How is tourism restricted in Antarctica?

One aspect of Antarctic tourism that restricts visitor numbers is the limited tourist season, this limitation is placed by the weather and in particular by the movements of sea ice. The limited tourist season does however coincide with the breeding season for most Antarctic wildlife with the potential for disturbance.

What animals are affected by climate change in Antarctica?

Scientists working in Antarctica have discovered an alarming rise in sea temperature that threatens to disrupt populations of penguins, whales, seals and a host of smaller creatures within a few decades.

What are the three most significant threats that the continent is experiencing in recent times?

Answer: 1 – Climate change / Global warming, resulting in a warming of the sea and loss of sea ice and land-based ice, this is greatest long-term threat to the region. 3 – Exploration and exploitation of mineral reserves, oil and gas.

How are animals in Antarctica affected by climate change?

Antarctic wildlife will also be affected by climate change. Krill often feed on algae that live underneath sea ice and krill populations have been declining around the West Antarctic Peninsula as sea ice has decreased.

Why are animals in Antarctica endangered?

Save Earth’s Animals! The animals of Antarctica and the Arctic live in some of Earth’s most challenging climates. Many of these animals face extinction at the hands of poachers, habitat loss, and climate change.

How is pollution affecting Antarctica?

The emission of pollutants like chlorofluorocarbons (CFCs) has been of greatest significance in the Antarctic because they have contributed strongly to the depletion of the ozone layer over the continent. This, in turn, has had consequences for animal and plant life which has been exposed to radiation.

What are the most immediate threats to Antarctica?

The most immediate threats are regional warming, ocean acidification and loss of sea ice, all linked to global levels of carbon dioxide.

How is Antarctica governed by the international treaty system?

The continent is governed by the Antarctic Treaty System, a series of international agreements that regulates research and tourism. So far the treaty has done a good job of conserving Antarctica’s environment and resources, said study co-author Diana Wall, a researcher at Colorado State University.

Why is Antarctica under a lot of pressure?

Warming and human visitors threaten Antarctica. (Image credit: Steven Chown et al, Science) Antarctica and its surrounding waters are under pressure from a variety of forces that are already transforming the area, scientists warn.

How is the loss of sea ice affecting the ecosystem?

“The foundation of the ecosystem is melting away,” said Hugh Ducklow, a biological oceanographer at the Marine Biological Laboratory in Woods Hole, Mass., who wasn’t involved with the study. For example, loss of sea ice has hurt the Adelie penguin, which lives on the ice; its populations have decreased by 80 percent since 1975.
