Ndi nyengo yakusamuka kwa grey whale kugombe lakumadzulo kwa North America.

Mbalame zotchedwa Grey whales ndi imodzi mwa nyama zoyamwitsa zomwe zimasamuka kwautali kwambiri padziko lapansi. Chaka chilichonse amasambira mtunda wa makilomita oposa 10,000 kupita ndi kubwerera pakati pa madambwe a ku Mexico ndi malo odyetserako ziweto ku Arctic. Pa nthawi ino ya chaka, anangumi omaliza akubwera kudzabereka ndipo oyambirira mwa amuna akupita kumpoto-11 adawonedwa sabata yoyamba yowonera njira ya Santa Barbara. Nyanjayi idzakhala ikudzaza ndi ana obadwa kumene pamene nyengo yoberekera ikufika pachimake.

Imodzi mwa ntchito zanga zazikulu zotetezera m'madzi zinali zothandizira kuteteza Laguna San Ignacio ku Baja California Sur, malo odyetserako anamgumi a grey ndi nazale - ndipo ndikukhulupirirabe, amodzi mwa malo okongola kwambiri padziko lapansi. Chakumapeto kwa zaka za m'ma 1980, a Mitsubishi adaganiza zokhazikitsa ntchito yayikulu yamchere ku Laguna San Ignacio. Boma la Mexico lidakonda kuvomereza izi pazifukwa za chitukuko cha zachuma, ngakhale kuti nyanjayi ili ndi mayina angapo ngati malo otetezedwa mdziko lonse komanso padziko lonse lapansi.

Kampeni yotsimikizika yazaka zisanu idakopa opereka zikwizikwi omwe adathandizira zoyeserera zapadziko lonse lapansi zomwe zidakhazikitsidwa ndi mgwirizano womwe unaphatikizapo mabungwe ambiri. Ojambula m'mafilimu ndi oimba otchuka adagwirizana ndi omenyera ufulu wa m'deralo ndi ochita kampeni a ku America kuti asiye ntchito zamchere ndi kubweretsa chidwi cha mayiko ku vuto la gray whale. Mu 2000, Mitsubishi adalengeza kuti akufuna kusiya mapulani ake. Tinapambana!

Mu 2010, omenyera nkhondoyi adasonkhana pa imodzi mwamisasa ya Laguna San Ignacio kukondwerera chaka cha 10 chipambanocho. Tinatenga ana a m’deralo pa ulendo wawo woyamba wokaona anamgumi—ntchito imene imathandiza mabanja awo kukhala m’nyengo yozizira. Gulu lathu linaphatikizapo ochita kampeni monga Joel Reynolds wa ku NRDC amene amagwirabe ntchito m'malo mwa zinyama za m'madzi tsiku ndi tsiku, ndi Jared Blumenfeld, yemwe wapitiriza kutumikira chilengedwe mu ntchito ya boma.

Komanso pakati pathu panali Patricia Martinez, mmodzi wa atsogoleri achitetezo ku Baja California amene kudzipereka kwake ndi kuyendetsa kwake kunanyamula malo ake omwe sakanawaganizira poteteza nyanja yokongolayo. Tinapita ku Morocco ndi ku Japan, pakati pa madera ena, kuti titeteze malo otchedwa World Heritage ndi kuonetsetsa kuti nyanjayi ikudziwika padziko lonse chifukwa cha zoopsa zomwe anakumana nazo. Patricia, mlongo wake Laura, ndi oimira ena ammudzi anali gawo lalikulu lachipambano chathu ndipo akupitirizabe kuteteza malo ena omwe ali pachiopsezo cha Baja California peninsula.

Kuyang'ana Zamtsogolo

Kumayambiriro kwa February, ndinapita ku Southern California Marine Mammal Workshop. Yolembedwa ndi Pacific Life Foundation mogwirizana ndi The Ocean Foundation, msonkhanowu wakhala ukuchitikira ku Newport Beach chaka chilichonse kuyambira January 2010. Kuchokera kwa akatswiri ofufuza akuluakulu kupita kwa akatswiri a zinyama zam'madzi mpaka Ph.D achinyamata. ofuna, otenga nawo gawo pamisonkhanoyi akuyimira magulu angapo aboma ndi maphunziro, komanso opereka ndalama ena ochepa ndi mabungwe omwe siaboma. Cholinga cha kafukufukuyu ndi pa zinyama zam'madzi ku Southern California Bight, dera la 90,000 lalikulu mailosi kum'mawa kwa Pacific lomwe likuyenda makilomita 450 m'mphepete mwa nyanja ya Pacific Ocean kuchokera ku Point Conception pafupi ndi Santa Barbara kum'mwera mpaka ku Cabo Colonet ku Baja California, Mexico.

Ziwopsezo kwa nyama za m'nyanja ndi zosiyanasiyana - kuchokera ku matenda omwe angoyamba kumene kupita ku kusintha kwa zinthu zam'nyanja ndi kutentha mpaka kuphana ndi zochita za anthu. Komabe, mphamvu ndi chisangalalo cha mgwirizano zomwe zimachokera ku msonkhanowu zimalimbikitsa chiyembekezo kuti tidzapambana kulimbikitsa thanzi ndi chitetezo cha zinyama zonse za m'nyanja. Ndipo, zinali zokondweretsa kumva momwe chiwerengero cha grey whale chikuchira chifukwa cha chitetezo cha mayiko komanso kukhala tcheru kwanuko.

Kumayambiriro kwa Marichi, tidzasangalala ndi zaka 13 zakupambana kwathu ku Laguna San Ignacio. Zidzakhala zowawa kukumbukira masiku ovutawo chifukwa ndikupepesa kunena kuti Patricia Martinez adataya kulimbana ndi khansa kumapeto kwa Januware. Anali mzimu wolimba mtima komanso wokonda nyama kwambiri, komanso mlongo wabwino, mnzake, komanso bwenzi. Nkhani ya nazale ya grey whale ya Laguna San Ignacio ndi nkhani ya chitetezo chothandizidwa ndi tcheru ndi kukakamiza, ndi nkhani ya mgwirizano wapakati, wachigawo, ndi wapadziko lonse, ndipo ndi nkhani yokonza kusiyana kuti akwaniritse cholinga chimodzi. Pofika chaka chamawa, msewu wawukulu wokonzedwa udzalumikiza nyanjayi ndi dziko lonse lapansi kwa nthawi yoyamba. Idzabweretsa kusintha.

Tikhoza kukhulupirira kuti zambiri mwa kusintha kumeneku n’zaphindu kwa anamgumi ndi midzi yaing’ono ya anthu imene imadalira zimenezo—komanso alendo amene ali ndi mwayi amene amaona zolengedwa zokongolazi chapafupi. Ndipo ndikuyembekeza kuti zikhala ngati chikumbutso kukhalabe othandizira komanso tcheru kuonetsetsa kuti nkhani yopambana ya grey whale imakhalabe nkhani yopambana.
