Lapho uhlobo oluthile lufa futhi kusele abantu abambalwa kuphela, umhlaba wonke ubuka ngokushaqeka njengokufa kommeleli wokugcina. Kwaba njalo ngeSudan, ubhejane wesilisa wokugcina omhlophe wasenyakatho owashona ehlobo eledlule.
Nokho, ucwaningo olwanyatheliswa ephephabhukwini elithi “” lwabonisa ukuthi cishe izinhlobo eziyisishiyagalombili zezinyoni eziyivelakancane kungenzeka ukuthi sezishabalele ngaphandle kokuqaphela umhlaba wonke.
Ucwaningo lweminyaka eyisishiyagalombili oluxhaswe yinhlangano engenzi nzuzo luhlaziye izinhlobo zezinyoni ezisengozini yokushabalala ezingu-51 lwathola ukuthi eziyisishiyagalombili kuzo zingahlukaniswa njengezingasekho noma eziseduze kakhulu nokushabalala: kwatholakala izinhlobo ezintathu sezingasekho, eyodwa engasekho emvelweni yasendle nezine. zisengcupheni yokushabalala.
Olunye uhlobo, i-blue macaw, lwavezwa efilimini yopopayi yango-2011 i-Rio, exoxa indaba yohambo lwe-macaw yesifazane neyeduna, okuwukugcina kwalolu hlobo. Kodwa-ke, ngokusho kokutholwe kulolu cwaningo, ifilimu yayineminyaka eyishumi sekwephuze kakhulu. Endle, kulinganiselwa ukuthi i-blue macaw yokugcina yafa ngo-2000, futhi abantu abangaba ngu-70 basahlala ekuthunjweni.
I-International Union for Conservation of Nature (IUCN) iyisizindalwazi somhlaba wonke esilandelela isibalo sezilwane, kanye ne-Birdlife International, evamise ukuhlinzeka ngezilinganiso ze-IUCN, ibika ukuthi izinhlobo ezintathu zezinyoni zibonakala zihlukaniswa ngokusemthethweni njengezingasekho: uhlobo lwaseBrazil i-Cryptic treehunter, abameleli bazo. zagcina ukubonakala ngo-2007; i-Brazilian Alagoas-gleaner, yagcina ukubonakala ngo-2011; kanye ne-Hawaiian Flower Girl enobuso obumnyama, yagcina ukubonakala ngo-2004.
Ababhali balolu cwaningo balinganisela ukuthi zingu-187 izinhlobo zezinto eziphilayo esezishabalele kusukela zaqala ukugcina amarekhodi. Ngokomlando, izinhlobo ezihlala eziqhingini yizona ezisengozini kakhulu. Cishe isigamu sokuqothulwa kwezinhlobo zezilwane kuye kwaqashelwa ukuthi kubangelwa izinhlobo ezihlaselayo ezikwazile ukusabalala ngamandla kuzo zonke iziqhingi. Kuphinde kwatholakala ukuthi cishe u-30% wabantu abanyamalalayo udalwe ukuzingela nokubamba izilwane ezingavamile.
Kodwa abalondolozi bemvelo bakhathazekile ngokuthi isici esilandelayo sizoba ukugawulwa kwamahlathi ngenxa yokugawulwa kwamahlathi nokulinywa ngendlela engafanele.
"Esikubonile kuqinisekisa ukuthi igagasi lokuqothulwa kwezinto eziphilayo liyakhula kuwo wonke amazwekazi, okubangelwa ikakhulukazi ukulahleka kwezindawo zokuhlala noma ukuwohloka ngenxa yezolimo nokugawulwa kwemithi okungalawuleki," kusho uStuart Butchart, umbhali oholayo nososayensi omkhulu e-BirdLife.
E-Amazon, eyake yacebile ngezinhlobo zezinyoni, ukugawulwa kwamahlathi kuwukukhathazeka okukhulayo. I-World Wildlife Fund, phakathi kuka-2001 no-2012, ngaphezu kwamahektha ayizigidi ezingu-17 amahlathi alahlekile. I-athikili eyanyatheliswa ngo-March 2017 kujenali ethi “” ithi indawo yase-Amazon ifinyelela endaweni ephakeme kakhulu yezemvelo - uma u-40% wendawo egawulwa amahlathi, i-ecosystem izoba nezinguquko ezingenakuhlehliswa.
ULouise Arnedo, isazi sesayensi yezinto eziphilayo nesikhulu esiphezulu se-National Geographic Society, uchaza ukuthi izinyoni zingaba sengozini enkulu yokushabalala lapho zilahlekelwa indawo yazo ngenxa yokuthi zihlala ezindaweni ezizungezile, zidla kuphela inyamazane ethile futhi zizalele ezihlahleni ezithile.
Uthi: “Uma indawo yokuhlala isinyamalele, nazo zizoshabalala.
Unezela ukuthi zimbalwa izinhlobo zezinyoni ezingabhebhethekisa izinkinga zokugawulwa kwamahlathi. Izinyoni eziningi zisebenza njengabasakazi bembewu ne-pollinator futhi zingasiza ekubuyiseleni izindawo ezinamahlathi.
I-BirdLife ithi kudingeka ucwaningo olwengeziwe ukuze kuqinisekiswe isimo sezinye izinhlobo ezine, kodwa akukho nesisodwa sazo esike sabonakala endle kusukela ngo-2001.
