Antarctica: the Last Continent
What does the title mean
Why should people protect Antarctica
Antarctica is the last and largest unspoiled wilderness area on Earth.
Antarctica belongs to no one and everyone.
Antarctica is a continent for science, as it is so unspoiled that it acts as a laboratory for the rest of the world where changes can be measured in isolation from the effects of man.
How can people protect it
Say No to mining, toxic and noxious chemicals and some wastes.
Establish specially protected areas.
Commercial fisheries in the Southern Ocean are controlled by the CCAMLR - Convention on the Conservation of Antarctic Marine Living Resources (南极海洋生物资源养护委员会).
