Scientific expeditions have found valuable minerals in some of these Antarctic areas, including antimony, chromium, copper, gold, lead, molybdenum, tin, uranium, and zinc. None approach a grade or size warranting economic interest. Also noneconomic are the very large deposits of coal and sedimentary iron.
What is the industry in Antarctica?
The International Association of Antarctic Tour Operators Antarctica’s biggest industry is tourism, with around 37,000 visitors per year, some 10,000 of whom will only cruise or fly without setting foot on land.
What would happen if we mined Antarctica?
Mining in Antarctica would be very difficult, dangerous and expensive as the climate is so harsh, the ice is very thick and Antarctica is very remote from major centres of population. This would make the transportation of minerals and equipment in and out of Antarctica hazardous.
What is the biggest threat to Antarctica?
Threats
- 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.
What was the main economic activity in Antarctica?
The exploitation of natural resources has been centred on the subantarctic and Antarctic seas and the coastal regions. From the late 18th century to the 1930s, whaling and sealing were the main economic activities in the Antarctic regions.
Why is Antarctica important to the global climate?
The Antarctic region has an important role in global climate processes. It is an integral part of the Earth’s heat balance. The heat balance, also called the energy balance, is the relationship between the amount of solar heat absorbed by Earth’s atmosphere and the amount of heat reflected back into space.
How are the natural resources of Antarctica protected?
Most of the resources found in the region are protected by laws and regulations, such as the Antarctic Treaty and the Protocol on Environment Protection, which imposed a ban on mining. The continent’s seas were once abundant with seals and whales but the population of these animals has since declined due to heavy sealing and whaling practices.
Is there a lot of tourism in Antarctica?
Tourism, while still largely confined to the Antarctic Peninsula, has expanded inland as far as the South Pole. The geology of Antarctica is known sufficiently well to allow rather certain prediction of the existence of a variety of mineral deposits, some probably large.
