Slash-and-burn agriculture, along with logging, and human encroachment, have hugely diminished the habitat available to these felines, which require extensive ranges capable of supporting the large herbivores that constitute the bulk of their diets. Poaching—for trophies and body parts used in Asian “medicine” —is thought to pose the greatest threat to tigers. Probably fewer than 4,000 are left in the wild. In 2014, China explicitly outlawed the consumption of endangered species, including tigers, whose bones and other organs are superstitiously believed to have magical curative powers.

Whooping Crane

In 1938, the first year a population survey was conducted, only twenty-nine whooping cranes remained in the wild. Three years later, only sixteen were left. Hunting and reduction of their wetland habitat had vitiated the population and concerted efforts to salvage remnant birds did not being until the late 1960s.

Today, there are over 400 birds, thanks in large part to innovative breeding programs. Though a plan that considered transferring whooping crane eggs to the nests of related sandhill cranes for fostering ultimately failed, captive rearing and reintroduction have established two wild populations in Florida, one of which has been taught to migrate to Wisconsin. Neither is self-sustaining. The only self-sustaining population migrates between Alberta, Canada, and Texas, U.S.

Slash-and-burn: cortar e queimar Fostering: promovendo

Encroachment: invasão Vitiated: adulterou, destruiu

Poaching: caça ilegal Captive rearing: criação em cativeiro

Wetland: pântano



De acordo com o texto, pode-se afirmar que

(A)
a caça ilegal é a única causa de estas espécies estarem na lista de animais em risco de extinção.

(B)
a invasão do homem ao hábitat desses animais é uma das principais causas de estarem quase extintos.

(C)
as populações de grou americano, situadas na Flórida e Winconsin, são autossustentáveis.

(D)
desde 2014, os tigres deixaram de ser caçados na China para servirem de troféus ou terem partes utilizadas na medicina.

Answer 1

Resposta: B ou A

Explicação: Pois nos seres humanos fazemos grandes estragos na natureza fazendo animais ficarem estintos uma delas e a caça ilegal e a modificação no habitat do animal.

Answer 2

Resposta:

é a letra b

Explicação:

pois essa alternativa faz mais sentido com o que o texto aborda
