A study involving 200 scientists worldwide “found that [26 million square miles] [68 million square kilometers] of land met ‘ wilderness ’ criteria, meaning that they have at least 70 percent of their original vegetation, contain fewer than [13] people per [square mile] [five people per square kilometer] outside urban areas, and have not been reduced to fragments of less than [3,900 square miles] [10,000 square kilometers]. ”
Suatu penelitian yang melibatkan 200 ilmuwan seluas dunia ” mendapati bahwa [68 juta kilometer persegi] daratan tergolong ’ padang belantara ’, artinya, wilayah itu paling sedikit memiliki 70 persen tumbuh - tumbuhan asli, ditinggali kurang dari [5] orang per [kilometer persegi] di luar daerah perkotaan, dan luasnya paling sedikit [10.000 kilometer persegi] ”.
