 <![endif]-->    A fauna brasileira é uma das mais ricas do mundo com 10% das espécies de répteis (400 espécies) e mamíferos (600 espécies), 17% das espécies de aves (1.580 espécies) a maior diversidade de primatas do planeta e anfíbios (330 espécies); além de 100.000 espécies de invertebrados (WALLAVER, 2000).

Algumas espécies da fauna brasileira se encontram extintas e muitas outras correm o risco. De acordo com o IBGE há pelo menos 330 espécies e subespécies ameaçadas de extinção, sendo 34 espécies de insetos, 22 de répteis, 148 de aves e 84 de mamíferos. As principais causas da extinção das espécies faunísticas são a destruição de habitats, a caça/pesca predatórias, a introdução de espécies estranhas a um determinado ambiente e a poluição (WALLAVER, 2000). O tráfico de animais silvestres movimenta cerca de 10 bilhões de dólares/ano, sendo que 10% corresponde ao mercado brasileiro, com perda de 38 milhões de espécimes (O GLOBO, 03/07/02).  A poluição, assim como a caça predatória, altera a cadeia alimentar e dessa forma pode haver o desaparecimento de uma espécie e superpopulação de outra. P. ex., o gafanhoto serve de alimento para sapos, que serve de alimento para cobras que serve de alimento para gaviões que quando morrem servem de alimento para os seres decompositores. Se houvesse uma diminuição da população de gaviões devido à caça predatória, aumentaria a população de cobras, uma vez que esses são seus maiores predadores. Muitas cobras precisariam de mais alimentos e, conseqüentemente, o número de sapos diminuiria e aumentaria a população de gafanhotos. Esses gafanhotos precisariam de muito alimento e com isso poderiam atacar outras plantações, causando perdas para o homem (IBAMA, 2001). É importante lembrar que o desaparecimento de determinadas espécies de animais interrompe os ciclos vitais de muitas plantas (O GLOBO, 03/07/02).
