english: When we burn and plow the Amazon rain forest so that we can have cheap land for ranching, when the last of the African bush gets converted to farms, when wild animals in China are hunted to extinction, human beings come into contact with wildlife populations that they've never come into contact with before, and those populations have new kinds of diseases: bacteria, viruses, stuff we're not ready for.
non_english: Kada palimo i oremo kišne šume Amazonije kako bismo imali jeftinu zemlju za imanja, kada se i poslednji afrički žbun pretvori u farmu, kada divlje životinje u Kini budu istrebljene zbog lova, ljudska bića dolaze u dodir sa populacijom divljači sa kojom nikad pre nisu bili u dodiru, a te populacije imaju nove tipove bolesti: bakterije, viruse, stvari za koje nismo spremni.
