In business today, it is sometimes very hard to make the right decisions.

在今日商業時代，去做出正確的決定有時是非常困難。

In a South American country, native people in the tropical rain forest capture beautiful birds and sell them to traders who in turn sell the birds to people in other countries.

在某一個南美國家，在熱帶雨林的原住民抓漂亮鳥 and 賣掉他們到交易商。交易商再轉賣到其它國家的人。 

Some of these birds are in danger of extinction, which means that their species or kinds would no longer exist on the earth.

這些鳥的一些是在絕種的危險狀態，這事意謂著他們的物種、物類將不在存在地球上。

The best thing would be for the government to restrict the buying and selling of these tropical birds, but then the preliterate native people would lose their means of survival.

這最佳的事情將會是因為政府去禁止買和販賣這些熱帶鳥，但那時這些不識字的原住民將會失去他們的生存的方法。

An alternative source of income for the people in these remote areas should be found so that on the one hand the birds can be protected and on the other the native hunters have a new way of making a living.

一個轉換收入來源對在這些遙遠地區的人民，該被找出，這樣的話 一方面 鳥類可以被保護，而另一方面原住民獵人有賺錢維生的新方法。
