Mhinduro Dziri Pazasi Pepasi: Zuva Renyika Yezvakatipoteredza 2012

naMark J. Spalding, Mutungamiriri weThe Ocean Foundation

June 5 izuva reWorld Environment Day, zuva rekusimbisa kuti hutano hwezvinhu zvakasikwa uye hutano hwevanhu hwakafanana. Nhasi tinorangarira kuti isu tiri chikamu chehurongwa hwakakura, hwakaoma, asi husina magumo.

Pakasarudzwa Abraham Lincoln Mutungamiriri, mazinga emuchadenga carbon dioxide akaverengwa muzvikamu 200-275 pamiriyoni. Sezvo hupfumi hwemaindasitiri hwakamuka uye huchikura kupota pasi, ndizvo zvakaitawo kuvapo kwecarbon dioxide mumhepo. Segasi rinopisa regreenhouse (asi risiri iro rega), zviyero zvecarbon dioxide zvinotipa mwero wekuyera kuita kwedu mukuchengetedza masisitimu atinovimba nawo. Uye nhasi, ndinofanira kubvuma nhau dzevhiki rapfuura dzokuti carbon dioxide kuverenga mumhepo pamusoro peArctic yakanga yasvika zvikamu mazana mana pamiriyoni (ppm)—mucherechedzo waitiyeuchidza kuti hatisi kuita basa rakanaka routariri sezvatinofanira kuita.

Zvisinei nekuti dzimwe nyanzvi dzinotenda kuti hapana kudzokera kumashure iko zvino takapfuura 350 ppm yecarbon dioxide mumhepo, pano paThe Ocean Foundation, tinopedza nguva yakawanda tichifunga nekusimudzira pfungwa ye. blue carbon: Kudzoreredza nekuchengetedza zvipenyu zvemugungwa kunobatsira kuvandudza kugona kwegungwa kuchengeta kabhoni yakawandisa mumhepo yedu, uye kunatsiridza kugara zvakanaka kwemarudzi anoenderana neaya ecosystem. Mafuro eSeagrass, masango emiti yemimango, nemadhamu emahombekombe ndivo vanobatana nesu mukusimudzira nharaunda yevanhu. Kuwedzera kwatinoita kudzoreredza nekuvadzivirira, zviri nani kubva mumakungwa edu.

Svondo rapfuura, ndakagamuchira tsamba yakanaka kubva kumukadzi anonzi Melissa Sanchez kumaodzanyemba kweCalifornia. Aititenda (mukubatana kwedu neColumbia Sportswear) nekuedza kwedu kusimudzira kudzoreredza meadow meadow. Sezvaakanyora, "Seagrass chinhu chakakosha chezvipenyu zvemugungwa."

Melissa ari right. Uswa hwegungwa hwakakosha. Ndiyo imwe yenzvimbo dzinochengeterwa mhuka dzegungwa, inonatsiridza kujeka kwemvura, inodzivirira mahombekombe edu nemahombekombe kubva kune dutu remhepo, uswa hwegungwa hunobatsira kudzivirira kukukurwa nekuteya sediment uye kudzikamisa pasi pegungwa, uye vanopa kwenguva refu kabhoni sequestration.

Nhau huru pazvikamu zve CO2 pamiriyoni imwe kumberi dzinobva ku chidzidzo chakaburitswa mwedzi wapera chinoburitsa pachena kuti huswa hwemugungwa hunochengeta kabhoni yakawanda kudarika masango. Muchokwadi, uswa hwegungwa hunotora kabhoni yakanyungudika kubva mumvura yegungwa iyo yaizowedzera kune acidification yegungwa. Mukuita izvi, zvinobatsira gungwa, kunyura kwekabhoni yedu hombe kuenderera mberi nekugamuchira kuburitsa kabhoni kubva kumafekitori edu nemota.

Via yedu SeaGrass Kura uye 100/1000 mapurojekiti eRCA, tinodzosera mafuro egungwa akakuvadzwa nechikepe pasi uye mavanga eprop, kudonhedza uye kuvaka kwemahombekombe, kusvibiswa kwezvikafu, uye nekukurumidza shanduko yenharaunda. Kudzoreredza mafuro zvakare kudzoreredza kugona kwavo kutora kabhoni nekuichengeta kwezviuru zvemakore. Uye, nekuvhara mavanga uye mipendero yakakasharara yakasiiwa negwara rechikepe uye kudhiraivha tinoita kuti mafuro akwanise kurasika nekukukurwa.

Tibatsirei kudzoreredza huswa hwegungwa nhasi, pamadhora gumi ega ega tichava nechokwadi chekuti sikweya tsoka yehuswa hwegungwa hwakakanganisika hwadzorerwa kuhutano.
