The total continent of Antarctica, from its mountains to the seas full of blue whales, emperor penguins and leopard seals, is, by means of international agreement, classified as a nature preserve. The Antarctic Treaty took effect in 1998, and doesn’t allow mining and oil drilling for at least fifty years anywhere within the boundaries of Antarctica. The treaty places a strong emphasis on the protection of the natural environment but not development. All wildlife threats including dogs and chemicals used for killing pests are also banned.
The agreement has been set by some countries to keep Antarctica free of commercialism and industrial development. This agreement was signed in 1991 by the 26 leading nations with scientific interest in the land. Some of the nations in the agreement are the United States, Russia, China, India, Japan, Argentina, Brazil, and most of the primary European nations.
The rules made by this treaty ended over 15 years of lobbying（游说）by environmental groups and put a stop to diplomatic(外交的）talks. In addition to preventing all oil drilling and mining, the 35 scientific outposts(前哨站） on Antarctica are required to remove all rubbish and clean up all places where unwanted waste is left. It keeps scientific stations from discharging untreated waste water into the surrounding waters.
Sled dogs were what explorers like Norway’s Roald Amundsen used to reach the South Pole in 1911. Dogs, however, were banned because they are a recent danger to the penguins and other native birds.
With laws enforced(实施）in 26 nations, each nation will be responsible for enforcing the rules individually. If the country’s government refuses to become involved when its citizens disobey the rules, the other nations would apply pressure to solve the issue. There are many people who see this treaty as an environmental success story.
