ecosystem was in27.Wild pigs attracted golden eagles from the mainland,and thoseflying28crashed the fox population.So the Nature Conservancy launched a29war against the pigs,completewith helicopters and sharp shooters.And it worked.Today,federal agencies are pulling the island fox from the Endangered Species List.Its thefastest-ever recovery of a mammal,joining peers like the Louisiana black bear as glowing successes in the history of theEndangered SpeciesAct.But the recovery of Santa Cruz Island isnt just about the fox.The Nature Conservancy has30war on a multitude-3-of invasive species here,from sheep to plants to the31Argentine ant.“Our philosophy with the island has always been,OK,32the threats and let the island go back to what it was,”says ecologist Christina Boser.And it

Online?A When Katlyn Burbidges son was 6 years old,he was performing some ridiculous song and dance typical of afirst-grader.But after she snapped a photo and started using her phone,he asked her a serious question:“Are you going topost that online?”She laughed and answered,“Yes,I think I will.”What he said next stopped her.“Can you not?”B Thats when it dawned on her:She had been posting photos of him online without asking his permission.“Werebig advocates of bodily autonomy and not forcing him to hug or kiss people unless he wants to,but it never occurred to methat I should ask his permission to post photos of him online,”says Burbidge,a mom of two in Wakefield,Massachusetts.“Now when I post a photo of him online,I show him the photo and get his okay.”C When her 8-month-old is 3 or 4 years old,she plans to start asking him in an age-appropriate way,“Do you wantother people to see this?”Thats precisely the approach that two researchers advocated before a room of pediatricians(儿科医生)last week at theAmericanAcademy of Pediatrics meeting,when they discussed the 21st century challenge of“sharenting,”a new term for parentsonline sharing about their children.“As advocates of childrens rights,we believe thatchildren should have a voice about what information is shared about them if possible,”says Stacey Steinberg,a legal skillsprofessor at the University of Florida Levin College of Law in Gainesville.D Whether its ensuring that your child isnt bullied over something you post,that their identity isnt digitally“kidnapped”,or that their photos dont end up on a half dozen child pornography(色情)sites,as oneAustralian momdiscovered,parents and pediatricians are increasingly aware of the importance of protecting childrens digital presence.Steinberg and Bahareh Keith,an assistant professor of pediatrics at the University of Florida College of Medicine,say mostchildren will likely never experience problems related to what their parents share,but a tension still exists between parentsrights to share their experiences and their childrens rights to privacy.E“Were in no way trying to silence parentsvoices,”Steinberg says.“At the same time,we recognize that childrenmight have an interest in entering adulthood free to create their own digital footprint.”They cited a study presented earlierthis year of 249 pairs of parents and their children in which twice as many children as parents wanted rules on what parentscould share.“The parents said,We dont need ruleswere fine,and the children said,Our parents need rules,”Keith-4-says.“The children wanted autonomy about this issue and were worried about their parents sharing information aboutthem.”FAlthough theAmericanAcademy of Pediatrics offers guidelines recommending that parents model appropriatesocial media use for their children,it does not explicitly discuss oversharing by parents.“I think this is a very legitimateconcern,and I appreciate their drawing our attention to it,”David Hill,a father of five,says.He sees a role for pediatriciansto talk with parents about this,but believes the messaging must extend far beyond pediatriciansoffices.“I look forward toseeing researchers expand our understanding of the issue so we can translate it into effective education and policy,”he says.G Theres been little research on the topic,Steinberg wrote in a law article about this issue.While states could passlaws related to sharing information about children online,Steinberg feels parents themselves are generally best suited tomake these decisions for their families.“While we didnt want to create any unnecessary panic,we did find some concernsthat were troublesome,and we thought that parents or at least physicians should be aware of those potential risks,”Steinberg says.They include photos repurposed for inappropriate or illegal means,identity theft,embarrassment,bullyingby peers or digital kidnapping.H But thats the negative side,with risks that must be balanced against the benefits of sharing.Steinberg pointed outthat parental sharing on social media helps build communities,connect spread-out families,provide support and raiseawareness around important social issues for which parents might be their childrens only voice.IAC.S.Mott survey found among the 56 percent of mothers and 34 percent of fathers who discussed parenting onsocial media,72 percent of them said sharing made them feel less alone,and nearly as many said sharing helped them worryless and gave them advice from other parents.The most common topics they discussed included kidssleep,nutrition,discipline,behavior problems and day care and preschool.J“Theres this peer-to-peer nature of health care these days with a profound opportunity for parents to learn helpfultips,safety and prevention efforts,pro-vaccine messages and all kinds of other messages from other parents in their socialcommunities,”says Wendy Sue Swanson,a pediatrician and executive director of digital health at Seattle ChildrensHospital,where she blogs about her own parenting journey to help other parents.“Theyre getting nurtured by peopletheyve already selected that they trust,”she says.K“How do we weigh the risks,how do we think about the benefits,and how do we alleviate the risks?”she says.“Those are the questions we need to ask ourselves,and everyone can have a different answer.”L Some parents find the best route for them is not to share at all.Bridget OHanlon and her husband,who live inCleveland,decided before their daughter was born that they would not post her photos online.When a few family membersdid post pictures,OHanlon and her husband made their wishes clear.“Its been hard not to share pictures of her becausepeople always want to know how babies and toddlers(学走路的孩子)are doing and to see pictures,but we made thedecision to have social media while she did not,”OHanlon said.Similarly,Alison Jamison of New York decided with herhusband that their child had a right to their own online identity.They did use an invitation-only photo sharing platform sothat friends and family,including those far away,cou
