A recent study by the World Conservation Society scientists has indicated that the world’s wilderness has reduced by a tenth in the past two decades.
The research findings published in the journal “Current Biology’’ on Thursday in New York, noted the wild areas that vanished are mostly in South America and Africa.
Prof. James Watson, of the University of Queensland, Australia, and the U.S. Wildlife Conservation Society in New York, added that only about 20 per cent of the world’s land area is sorted as wilderness currently.
The scientists said that the concept of wild areas or wilderness means landscapes free of human disturbances such as housing, development and industry.
He said that the findings are based on a map of worldwide wilderness now compared with the condition in the early 1990s.
“The distribution of different colours in the map shows that around 3.3 million kilometres of wild areas has reduced during the period of time.
Watson warned that the international policy mechanisms must recognise the actions needed to maintain wilderness areas before it is too late.
