If you yelled for 8 years, 7 months and 6 days you would have produced enough sound energy to heat one cup of coffee.
(Hardly seems worth it.)
If you farted consistently for 6 years and 9 months, enough gas is produced to create the energy of an atomic bomb..
(Now that’s more like it!)
The human heart creates enough pressure when it pumps out to the body to squirt blood 30 feet.
(O.M.G.!)The recent recall of half a billion eggs has been bad news for the egg-consuming public. But it's been stellar for the birds. The recall has placed chickens -- and where they come from -- front and center in the national consciousness.
As a result of all the media coverage surrounding the recall -- from Diane Sawyer to Amy Goodman to multiple stories in the New York Times to CNN's Jane Velez-Mitchell -- countless Americans have been shocked to discover just how hideously chickens are treated in this country.
And that's a good thing for the birds, whose plight deserves to be better understood. At any given point in the U.S., hundreds of millions of chickens are crammed inside tiny cages, unable even to spread their wings or breathe fresh air. They live like this for their whole lives, each egg representing 34 hours of this unmitigated misery per bird. And Americans eat another 9 billion (yes billion) chickens annually; that's 200 times as many chickens as cattle, and almost 100 times as many chickens as pigs -- this means that anyone who "stops eating red meat" and replaces it with chicken or eggs is actually causing a LOT more suffering.
This new spotlight on chicken factory farms will surely create untold numbers of new vegetarians. But some people may still try to justify their meat and egg consumption. On that subject, a few years back, I wrote a letter to the New York Times, in which I noted that "eating your dogs or cats would be morally preferable [to eating chickens or other farmed animals], since they would have led a good life until you killed them." Boy did I get some angry mail; some people actually thought I was in favor of eating Fido and Fluffy, even though my letter ends with a clear entreaty to stop eating all animals.
关于第二点认为鸡没有宠物聪明。实际上，鸡的认知能力远远大于猫狗。一项研究用充分的证据表明了这一点。几周前，此研究成果荣获了澳大利亚博物馆颁发的年度“Eureka Prize”. 在这项研究中，澳大利亚农学院的权威研究人员发现鸡是“具有社会性和智慧的生物。它们的马基雅弗利主义的倾向性（Machiavellian tendencies） 使它们在说话时会根据听众的不同做出调整”。
I have wondered for decades about this curious lapse in logic: Why on earth do people who, to their credit, loathe cruelty to dogs and cats, think nothing of eating a chicken, turkey, pig, or other farmed animal? After all, these animals are made of flesh, blood, and bone--just like dogs and cats. They experience the exact same five physiological senses (i.e., they see, hear, smell, taste, and feel). And they feel pain -- just like dogs, cats, and we do.
So what gives?
I did a small survey, asking ten people on the streets of Baltimore why they eat chickens, and all ten offered some variation of 1) "chicken is healthier than red meat"; and 2) "well, chickens are not as smart as pets."
The problem with their logic: It's just not true.
On the first point, health and wellness savant Kathy Freston dealt with what she calls "the false dichotomy" of giving up red meat to eat more birds. In a piece that I hope you will read, she discusses, especially, the issues of health and the environment, arguing convincingly that chicken consumption is just as bad for you and the environment as consuming cattle and pigs.
And on the intelligence point: In fact, chickens have cognitive capacities that are beyond those of both dogs and cats, as was made abundantly clear in a study that, just a few weeks ago, won one of two Australian Museum "Eureka Prizes" for the year. In the study, researchers from the top Australian agricultural school found that chickens are "social, intelligent creatures complete with Machiavellian tendencies to adjust what they say according to who is listening."
According to the Australian Museum's press release, the study proves that "chickens can share remarkably precise information about the presence of predators and the discovery of food. They typically communicate using sound variations, postures and visual displays."
The scientists point out that this method of sophisticated communication is a first with non-human animals. No animal behaviorist has found this type of detailed communication in any other non-human animal, including primates.
As just a few more examples (read more, and check out all the citations, here):
According to a study in the journal Animal Behavior, chickens "can anticipate the future and demonstrate self-control, something previously attributed only to humans and other primates." The scientists note that "like humans, chickens evolved an impressive level of intelligence to help improve their survival."
Chickens can learn from watching the actions of other chickens (including on a video, which you can watch in the video "Stimulus Response"). In another experiment, a scientist taught a group of chickens to peck red and green buttons a certain number of times to obtain a food reward. When a new group of chickens watched those who had learned how to push the buttons for food, the new chickens quickly caught on by watching the others.
Chickens know that something they can't see still exists -- something that is "beyond the capacity of small children."
