Amahlathi, ngakumbi xa kukho uninzi lwazo, ngoomatshini abamangalisayo ukunciphisa ukukhutshwa kwekhabhoni kumhlaba ojikeleze umhlaba. Ngokuqinisekileyo ubone esi sikimu kwincwadi yesikolo: Imithi ifunxa i-carbon diokside isuka kwimozulu kwaye iguqule ngenxa yenkqubo ye-phobbon, egcinwe "ngohlobo lwenkuni kunye nezityalo. Kodwa kuyo nayiphi na i-ecosystem, ngakumbi i-ofisi, njengemithi yemvula yeAmazon, ayikho kuphela imithi engapheliyo-kukho umhlaba, amanzi kunye nomoya, onke onyulo. Iqela lezizwe lutsha nje lezazinzulu ngexesha lophando lokuqala lweza kwisigqibo sokuba i-jungle iamazonia iqala ukutshintshela umoya womhlaba, kwaye ayipholisi. Ngenxa yoko, kwiindlela ezininzi, ngenxa yezisombululo zabantu, enye yezona ndawo ziphambili zemvula ezisemhlabeni ngoku zinokwabela igesi eluhlaza okwethutyana kunokonwaba, ukutshintsha kwemozulu.
Kwenzeka ntoni ku "iiplanethi ezikhanyayo"?
Amahlathi amahlathi e-Amazonian kudala abekwe njengekhabhoni yekharbon kunye nendalo kumlo wokulwa inkxwaleko. Nangona kunjalo, uqeqesho lwakutsha nje lulumkisa ukuba ubuntu bungaphulukana noncedo lwamahlathi atshisayo ngokuqhubeka kwamahlathi. "Ukusika amahlathi ukuthintela i-carbon yokuthathwa kwaye le yingxaki enkulu," watsho uChristopher Kovi, ongumbhali ophambili wesifundo esitsha kudliwanondlebe nejografi lelizwe.
Kwisifundo esisandula ukupapashwa kwimida emahlathini kunye nejenali yeHlabathi, ukuphuma ngaphandle kwekharbon dioknes, njenge-methane ukusuka kwimilambo emnyama evela kwimililo yehlathi.
Kuyathakazelisa ukuba iziphumo zeZifundo ebeziqhutywa ngaphambili zenze ukuba amahlathi ajikeleze umhlaba asafumana i-7.6 yezigidi zeetawuli ze-mpuma ye-shorbon minyaka le, kodwa amahlathi e-mpuma akwi-Ania Loons ye-carbon ngoku yinguqulo kusetyenziso lomhlaba, Xela i-ecotchch.

Jungle i-iamon kunye notshintsho lwemozulu
Njengamanani ezifundo zangaphambili ezibonisiweyo, iAmazon yaseBrazil yayisele ingumthombo ococekileyo wekhabhoni ukusuka ngo-2001 ukuya ku-2019, nangona iphela iphela i-carbon abufunber. Idatha entsha, nangona kunjalo, inyanzeliswa ukuba yothukile, kuba emva kwemililo engama-2020 eneeplauls "ze-15 ezikhanyayo", kule minyaka ili-15 ilandelayo, le ngukumkani inokuguqulela komnye umthombo we-CO2.
Ngexesha lomsebenzi, izazinzulu zazijonga izinto ezininzi phakathi kweAmazon, kubandakanya ukusika amahlathi, imililo kunye neemeko zemozulu. Izigqibo ezibangela iziphumo zibonisa ukuba iigesi zegreenhouse, ezinjenge-methane kunye ne-nitrogen, ziphoswa kwichibi laseAmazon kwaye ngoku kunokwenzeka ukuba ngaphezulu kwendawo yokufumana imveliso.
Uyabona, yintoni ekufuneka uyazi ngemililo eBrazil?
Esi sisifundo sokuqala apho imicimbi yemisebenzi yoluntu kunye nendalo ithathelwa ingqalelo, enokuba negalelo kutshintsho lwemozulu, kunye negesi eluhlaza, kwaye ayisiyo nje i-co2. Ngaphambili, izazinzulu zixela kwangaphambili ukuba ezi zinto zinokukhokelela ekunciphiseni kwamahlathi emvula ukuze afumane i-carbon diokside ukusuka kwimozulu, enceda ekuhlawuleni ukukhutshwa. Ngokukodwa ukhathazekile malunga nezazinzulu ngekamva lommandla, malunga noko i-ramoti yam ye-ramoti yam ixelelwe malunga nezinto zayo.
- I-carbon emnyama imele ngaphandle kwesiphumo somlilo omkhulu. Babone amasuntswana kwikharbhon evuthayo efumana ukukhanya kwelanga kunye nokuphucula ukufudumeza.
- I-nitrogen iveliswa ngokwemvelo ngamahlathi, ukuphuma kwegesi kuyandiswa xa imigxobhozo yomile, kwaye ukuloga kuyancitshiswa emhlabeni.
- I-methane ikhutshwa ngokwemvelo ngamahlathi ashinyeneyo kwiintsholongwane kumhlaba omanzi, ocociweyo kwimozulu emithini. Kwixa elidlulileyo, ukukwazi kuka-Amazonia ukuqokelela ukuphuma kwe-carbon anti-methane. Umsebenzi woluntu okwangoku unciphisa amandla ehlathi ukuze ufumane ikharbon, kuba ezona zikhukula zenziwe izikhukula, ukwakhiwa kwamadama kunye nokutyisa kwemfuyo kwabele i-methane.
Iya kuba yinto enomdla kuwe: iya kuba yintoni ihlabathi ngonyaka ka-2050, ukuba awuyeki ukutshintsha kwemozulu?
"Sihlutha amathuba ama-Amazon ukuze afumane ikharbon diokside evela emoyeni, kwaye anyanzela ukwaba ezinye iigesi eziluhlaza," babhala ababhali bomsebenzi wesayensi. Ngethamsanqa, abaphandi bakholelwa ukuba kusekho ixesha lokutshintsha umonakalo ukuba siyekile ukukhutshwa kwi-fuels yefosili, ukunciphisa imizamo yokutyala imithi-kwaye yonke le nto isezantsi kweplanethi.
Iingcebiso ngokubanzi ezivakalayo zezazinzulu zibandakanya ukunciphisa ukukhutshwa kwe-fossil fullion; yeka ukusika amahlathi; Ukunciphisa ukwakhiwa kwendawo yamadama kunye nokudluliselwa kwemithi. Kwaye ucinga ntoni, singasindisa iplanethi evela kutshintsho lwemo ngokukhawuleza? Impendulo izakulinda apha, nakwiikhomenti kweli nqaku.
