3D mpo ukulima ngaphansi kwamanzi ukusindisa izilwandle

Izilwandle, imihosha, imifula, amachibi, kuyilapho lezizinda zamanzi zivame ukuphathwa kabi abaningi, abanye benza konke okusemandleni abo ukuze babuyisele izidalwa ikhaya elinempilo. Omunye walabo bantu nguBren Smith, indoda ekholelwa ukuthi abadobi bangazuza embonweni wayo wokulima ngaphansi kwamanzi. Futhi hhayi ukubeka ukudla nje emapuletini emindeni kodwa nokudala namathuba emisebenzi.

Kubadobi, ukulima ngaphansi kwamanzi ngeke nje kuzuzise ngomsebenzi kodwa kuzokwandisa inani lalokho abakudobile. Ngokutshala imali kule ndlela yokulima enembile, abantu bendawo abathola ukudla ekubambeni bayokwazisa ukunakekelwa okungagcini ngokubamba kodwa nomnotho walapho kuvela khona ukudla.

Ingadi kaBren eqondile

Bren Smith uchaza ipulazi lakhe elingaphansi kwamanzi le-3D “njengengadi eqondile” eyenziwe ngezinhlobonhlobo zezimila zasolwandle, amahange okuvikela iziphepho namakheji ama-oyster ngaphansi anezimbaza ezigqitshwe phansi. Izintambo ezintantayo ezivundlile zihlala phezulu (Chofoza lapha ngesithombe sayo.)  Esinye sezici eziphawuleka kakhulu ukuthi (njengoba uBren ekubeka) "inomthelela ophansi wobuhle." Lokhu kusho ukuthi incane ngosayizi futhi ayiphazamisi noma iphazamise ubuhle bolwandle.

Smith iyaqhubeka ichaza ukuthi: “Ngenxa yokuthi ipulazi limile, linendawo encane. Ipulazi lami lalingamahektha ayi-100; manje isifinyelele kumahektha angu-20, kodwa ikhiqiza ukudla okuningi kakhulu kunangaphambili. Uma ufuna 'okuncane kuhle,' nansi. Sifuna ezolimo zasolwandle zinyathele kancane."

Isisho esithi "okuncane kuhle" noma "izinto ezinhle ziza ngamaphasela amancane" kuyinto okufanele ikhuthazwe lapha. Enye indlela lokhu okwenziwa ngayo noBren nethimba lakhe umgomo wabo omkhulu: ukuhlukahluka.

Empeleni, bafuna ukukhulisa ukudla okunempilo kwakho konke ukuphila olwandle. Bahlose ukutshala izinhlobo ezimbili zokhula lwasolwandle (i-kelp ne-Gracilaria), izinhlobo ezine ze-shellfish futhi bazovuna usawoti ngokwabo. Lokhu kuphinde kuchazwe ngevidiyo lapho uBren echaza khona ukuthi uhlela kanjani bridge kokubili ukulima umhlabathi nolwandle. Ukuze uthole ukwaziswa okwengeziwe, ungavakashela i- igagasi eliluhlaza Iwebhusayithi.

Ngamanye amazwi, le ingadi eqondile izosiza hhayi kuphela ukubuyisela ukudla okungcono kodwa umnotho ongcono wezilwandle. Ngokuvamile abantu bakhathazeke ngokuthi ulwandle selugcwele udoti; okungase kuxoshe abanye ekudleni ukudla kwayo okunomsoco. Okufanele sikuqonde ukuthi abantu abaningi bakholelwa olwandle oluhlanzekile futhi benza konke okusemandleni abo ukuze lokho kwenzeke.

Izinkathazo zikaBren

Manje ake sibheke izinkinga zamanje mayelana nendlela ukudoba okwenziwa ngayo namuhla. Okokuqala, uBren uthi kuningi ukudla okungenamsoco kukhiqizwa nsuku zonke. Ikakhulukazi, embonini yokudoba, ukhathazekile ngokuthi izibulala-zinambuzane ezisetshenziswa kubuchwepheshe obusha kanye nokujova izinhlanzi ngama-antibiotic kudala umonakalo omkhulu. Akugcini nje ngokulimaza imizila yamanzi nezinhlanzi kodwa futhi kungase kucekele phansi amabhizinisi. Lesi simo siyinkinga evamile emagatsheni amaningi emboni yezokudla. Kungenxa yezinkampani ezifuna ukukhiqiza ngobuningi lokho ezikuthengisayo ukuze zihlale phezu kwezimbangi.

Elinye iphuzu alenzayo uBren elokuthi ukuguquguquka kwesimo sezulu “kuyindaba yezomnotho” hhayi indaba yezemvelo. Lokhu kuyiqiniso hhayi embonini yokudoba kuphela kodwa kuzo zonke izimboni ezidinga ukukhiqizwa ngobuningi. Amabhizinisi amakhulu asebenza ngale ndlela ekhiqizwe ngobuningi cishe ngeke alalele "umfanyana," kodwa uma umlayezo wakhiwe "ngolimi" lwawo, angazuza kakhulu endleleni eyongayo. UBren uzama ukuhlinzeka ngebhizinisi elihlanzekile ukuze imboni yazi kabanzi ukuthi ithathaphi ibhizinisi layo. Kunjengoba uBren ethi, "Umsebenzi wami awukaze ube ukusindisa ulwandle; ukubona ukuthi ulwandle lungasisindisa kanjani."

Umnikelo womndeni wakwa-Cousteau ekulondolozweni kolwandle

UBren ukhulume amazwi acashunwe kaJacque Cousteau aphawulekayo athi: “Kumelwe sitshale ulwandle futhi seluse izilwane zalo sisebenzisa ulwandle njengabalimi esikhundleni sokuba ngabazingeli. Yilokho impucuko emayelana nayo — ukulima esikhundleni sokuzingela.”

Ingxenye ephawuleka kakhulu yaleyo ngcaphuno isekupheleni lapho ethi "ukulima esikhundleni sokuzingela." Isizathu siwukuthi abadobi abaningi bavame ukugxila engxenyeni "yokuzingela" yebhizinisi labo. Bangase bazizwe benesidingo sokugxila ezinombolweni kunokuba babheke ukuthi benzani hhayi emnothweni wokuthi bakuphi ukuzingela kodwa lokho abayikho ukubamba.

Ekhuluma ngoCousteau, umzukulu wakhe (Fabian) kanye nethimba lakhe labacwaningi abavela e-Fabien Cousteau Ocean Learning Centre basebenzisa ukuphrinta kwe-3D kwezixhobo zamakhorali. Bakusebenzise lokhu ngokufaka izixhobo zokwenziwa zokuqala phansi olwandle eBonaire, isiqhingi saseCaribbean eduze kwaseVenezuela. Lezi zinto ezimbili eziqanjiwe zingase zihambisane kahle ngoba u-Bren uhlinzeka ngomthombo onempilo wokudla nomnotho futhi u-Fabien udala isakhiwo esisha saphansi kolwandle.

Izinselelo ezintathu okufanele kubhekwane nazo

UBren unethemba lokuthi uzobhekana namaprimary amathathu izinselelo: Eyokuqala eyokubeka ukudla okumnandi emapuletini abantu kungakhathaliseki ukuthi kusekhaya noma ezindaweni zokudlela—ikakhulukazi ezindaweni zasemakhaya. ukweqisa futhi ukungavikeleki kokudla. Udaba olukhona manje ngalokhu ukuthi ukudoba ngokweqile kuzoqhubeka kuze kube yilapho amabhizinisi etshala imali futhi eqonda ukusungulwa kukaBren.

Okwesibili, "ukuguqula abadobi babe abalimi basolwandle abavuselelayo." Ngamagama abantu abavamile, kumane kusho ukuthi ufuna abadobi baqonde ukuthi kufanele belaphe lokho abakwenzayo Ukuzingela ngenhlonipho futhi abe mnene emzini wabo.

Okokugcina, ufuna ukwakha “umnotho omusha oluhlaza okwesibhakabhaka ongabukhi kabusha ukungabi nabulungiswa komnotho omdala wezimboni.” Ngokuyinhloko, ufuna ukugcina imboni inempilo kuyilapho egcina okuhle komnotho omdala. ihlangana-nendlela entsha.

Umongo walezi zinselelo ukuthi uma abadobi bezokwenza ukuzingela, badinga ukunikeza izidalwa ikhaya elihlanzekile zokuhlala futhi balalele labo abafuna ukuhlinzeka lokho.
