Mayankho Ali Pansi Pansi Pamwamba: Tsiku Lachilengedwe Padziko Lonse la 2012

ndi Mark J. Spalding, Purezidenti wa The Ocean Foundation

June 5 ndi Tsiku Lachilengedwe Padziko Lonse, tsiku lotsimikiziranso kuti thanzi lazinthu zachilengedwe ndi thanzi la anthu ndizofanana. Lero tikukumbukira kuti ndife mbali ya dongosolo lalikulu, lovuta, koma lopanda malire.

Pamene Abraham Lincoln anasankhidwa kukhala Purezidenti, mpweya wa carbon dioxide unawerengedwa mu magawo 200-275 pa milioni. Pamene chuma cha mafakitale chinayamba kukula ndikukula padziko lonse lapansi, momwemonso kukhalapo kwa carbon dioxide mumlengalenga kunayamba. Monga mpweya wowonjezera wowonjezera kutentha (koma osati wokhawo), kuyeza kwa carbon dioxide kumatipatsa chiyerekezo choyezera momwe timagwirira ntchito pochirikiza machitidwe omwe timadalira. Ndipo lero, ndiyenera kuvomereza nkhani ya sabata yatha yakuti mawerengedwe a carbon dioxide m'mlengalenga pamwamba pa Arctic anali akufika magawo 400 pa milioni (ppm) -chizindikiro chomwe chinatikumbutsa kuti sitikuchita ntchito yabwino yoyang'anira momwe tiyenera kuchitira.

Ngakhale akatswiri ena akukhulupirira kuti palibe kubwerera mmbuyo tsopano popeza taposa 350 ppm wa carbon dioxide mumlengalenga, kuno ku The Ocean Foundation, timakhala nthawi yochuluka kuganizira ndi kulimbikitsa lingaliro la carbon carbon: Kubwezeretsa ndi kuteteza zamoyo zam'madzi kumathandiza kuti nyanjayi ikhale ndi mphamvu yosungira mpweya wochuluka m'mlengalenga mwathu, komanso kumapangitsa kuti zamoyo zomwe zimadalira zachilengedwe zizikhala bwino. Udzu wa m'nyanja, nkhalango za mangrove, ndi madambo a m'mphepete mwa nyanja ndi ogwirizana nawo pa chitukuko chokhazikika cha anthu. Tikamakonzanso ndi kuziteteza, m'pamenenso nyanja zathu zimayenda bwino.

Sabata yatha, ndinalandira kalata yabwino kuchokera kwa mayi wina dzina lake Melissa Sanchez kummwera kwa California. Amatithokoza (mumgwirizano wathu ndi Columbia Sportswear) chifukwa cha zoyesayesa zathu zolimbikitsa kubwezeretsa dambo la nyanja. Monga momwe adalembera, "Seagrass ndi chinthu chofunikira kwambiri pazachilengedwe zam'madzi."

Melissa akulondola. Udzu wa m'nyanja ndi wofunikira. Ndi imodzi mwazosungirako za m'nyanja, imapangitsa kuti madzi azimveka bwino, imateteza magombe athu ndi magombe athu ku mphepo yamkuntho, madambo a m'nyanja amathandizira kupewa kukokoloka mwa kutsekereza zinyalala ndikukhazikika pansi pa nyanja, ndipo amapereka mpweya wautali wautali.

Nkhani zabwino pamagawo a CO2 pa miliyoni kutsogolo zikuchokera ku a kafukufuku yemwe adatulutsidwa mwezi watha omwe akuwonetsa kuti udzu wa m'nyanja umasunga mpweya wambiri kuposa nkhalango. M'malo mwake, udzu wa m'nyanja umatulutsa mpweya wosungunuka m'madzi a m'nyanja zomwe zikanawonjezera acidity ya m'nyanja. Pochita izi, zimathandiza nyanja, nkhokwe yathu yaikulu ya carbon ikupitirizabe kulandira mpweya wochokera ku mafakitale ndi magalimoto athu.

Kudzera mu SeaGrass Grow ndi 100/1000 Ntchito za RCA, timabwezeretsa udzu wa m'nyanja womwe udawonongeka ndi mabwato ndi zipsera, kugwetsa ndi kumanga m'mphepete mwa nyanja, kuipitsidwa kwa michere, komanso kusintha kwachangu kwa chilengedwe. Kubwezeretsanso madambo kumabwezeretsanso kuthekera kwawo kutenga kaboni ndikusunga kwazaka masauzande. Ndipo, pomanga zipsera ndi m'mbali mwamaboti zomwe zimasiyidwa ndi mabwato ndikuphwanyidwa, timapanga madambo kukhala olimba ndi kukokoloka.

Tithandizeni kubwezeretsa udzu wa m'nyanja lero, pa $ 10 iliyonse tidzaonetsetsa kuti phazi lalikulu la udzu wowonongeka wabwezeretsedwa ku thanzi.
