Inmunologia

Australia is such an isolated continent with so few people living there that most national policy dealing with resources will have to take into consideration the nation being soisolated. For example the interior of Australia (over 40% of its landmass) receives less than 10 inches of rain a year, which leaves huge open stretches of land full of minerals untouched.In the last 40 years the Australian federal government has attempted to connect north to south and east to west, but still the vast open land of Australia remains unsullied by humanactivities. The first disadvantage is that there is a limit to how far economic development can take place. Human population growth is not explosive because of lack of livable land,trade and market goods are confined to surface transportation, and domestic production of energy is limited to availability of natural resources.

Most people live along the coasts in sixmain cities: Brisbane, Sydney, Melbourne, Adelaide, Perth, and Darwin. Human economic developments surrounding these six cities do not have the same negative impact overall onAustralia’s ecological status. Unlike in the U.S. where most natural resources (rivers, lakes, mountain ranges, etc.) were developed to provide electricity or recreational opportunity, inAustralia most of its interior land remains hostile and resistant to any human efforts in conquering it. Over the last 40,000 years the Aborigines of Australia are the only human groupable to live off the land and most researchers would attribute their success to their ability of being in harmony with the land.

Perhaps the biggest advantage of Australia is thelesson that we learn as humans to live productively and unobtrusively with the land. The valuable lesson is that modern economic activities can be deployed peacefully along with nature.
