我好“無辜”的

　　Actually, dog poop turns out to have a pretty big environmental impact. If you think that two in five households in the U.S. have at least one dog and that about forty percent of Americans don't clean up after their pooches, well, all that poop really adds up. In fact, it's what scientists call the Fido hypothesis.

　　狗狗便便嚴(yán)重污染環(huán)境。如果美國(guó)2/5家庭就養(yǎng)一只狗狗且當(dāng)中大約40%的主人不收拾狗狗的便便。所有這些便便加起來也就是科學(xué)家說的“狗狗”假說。(Fido是對(duì)狗狗通用的稱呼)。

　　Hey, my dog's name is Fido.

　　我的狗狗就叫Fido。

　　They conjecture that a lot of that waste ends up in waterways. Recent studies, in fact, suggest that dogs are in third or fourth place on the list of contributors to bacteria in water. Talk about gross—fecal matter is full of disease-causing bacteria like E. Coli, salmonella, and giardia.

　　科學(xué)家推想，水道阻塞的罪魁禍?zhǔn)拙褪沁@些便便。近日有研究表明，造成水里滋生細(xì)菌的“元兇”狗狗排第三或第四。令人作惡的這些細(xì)菌可以致癌，比如：大腸埃希菌、沙門氏菌、鞭毛蟲

　　Now that bacteria-tracking methods have gotten better, scientists estimate that in some areas, 20 to 30 percent of the bacteria in a stream comes from dogs.

　　細(xì)菌源追蹤技術(shù)的日臻完善，科學(xué)家估計(jì)，部分地區(qū)20%到30%的細(xì)菌是由狗狗造成的。

　　Really? That can't be good!

　　真的嗎?那可不妙!

　　And the thing is, pollution from dogs is relatively easy to control. All you have to do is scoop when they poop.

　　其實(shí)，狗狗造成的環(huán)境污染相對(duì)來說很容易避免，你需要做的只是在將狗狗的便便鏟干凈。
