英語聽力文摘464 狗狗和環(huán)保
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.
Hey, my dog‘s name is 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.
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.
Really? That can’t be good!
And the thing is, pollution from dogs is relatively easy to control. All you have to do is scoop when they poop.
我好”無辜“的
狗狗便便嚴重污染環(huán)境。如果美國2/5家庭就養(yǎng)一只狗狗且當中大約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家說的“狗狗”假說。(Fido是對狗狗通用的稱呼)。
我的狗狗就叫Fido。
科學家推想，水道阻塞的罪魁禍首就是這些便便。近日有研究表明，造成水里滋生細菌的“元兇”狗狗排第三或第四。令人作惡的這些細菌可以致癌，比如：大腸埃希菌、沙門氏菌、鞭毛蟲
細菌源追蹤技術的日臻完善，科學家估計，部分地區(qū)20%到30%的細菌是由狗狗造成的。
真的嗎?那可不妙!
其實，狗狗造成的環(huán)境污染相對來說很容易避免，你需要做的只是在將狗狗的便便鏟干凈。
