Ii-herbicides zemikhabo zicatshulwa njengomphakathi omsebenzisi ukucima umhlaba nokuthi umhlaba omkhulu wamathathu. Le mpahathi yakwesintsi yiyaqondiswa ngokuphumeleyo kuhlanganisa umhlaba, ngoko ke uyaqondiswa ngokuphumeleyo ukucima kwabo. Kodwa ngokushesha ngezinye izinto ezitholakalayo nezinhlonoho, zihlabeleka kakhulu. I-herbicide ephakathi le rai ecimali kuyiboniso ebizungulayo kusendaweni saseMntu nokuba yindawo yesikhathi.
Kunezinye eziningi zokuthi amakhemikali akhawulizi kuyenza imiphumela yezilungiselelo. Umphumela omkhulu oyo kungakwenzeka ngokuba kube ngenxa yokuziphatha izinkqubo zethathu lokuthatha amanzi ethathekileyo. Lokhu lube umphumela wokuqala ngoba kunomoya, okanye amakhemikali azikhishwe emva kokuthi amaseed wezintsha nokubhala, baze bekhuliswe ngamaphandle kwiMfula, iDamo nokwiStream ezinikezelako amanzi, lokho kungaba amanzi ayahlukene ukusuka ukuya kuthiwa ngokuphelele kanye nokuthi abantu abesihlale esine amanzi. Ngokwesiphi, amakhemikali angakho kungabonisa indlela yokugcina ukudla kwemibophelelo. Zingakho ngezinye izinhlobo zezinto ezingazithandela ukuthi zizama ukucima izinja noma izinsimu namanqaku lowo lula amabhophelelo ebizwa ngazo nokuthi bengacita amabhophelelo abizwa ngazo nokuthi bengacita amanzi amaziphumayo. Kufuneka kuhlanganiswe ngokuba kungabonisa ukuthi amakhemikali (izinto ezikhona) ezifanele kungabonisa ukuthi kuhlanganiswe ngokuba kungabonisa ukuthi kuhlanganiswe ngokuba kungabonisa ukuthi kuhlanganiswe.
Kunezimo zakahle ezinene ezinjalo abafumatha babephumelela ukwenza imigrowth yabo esiphakeme kwaye esisodwa ngokubona nokuthuthukiswa phakathi komhlaba nokufundziswa ngenqanawe yokugcina izinto elizicatshulwa zokusebenzela. Izimvelo ezibonakalisekile okuhle kuzofuneka kuhlala ngokusetyenziswa kwezincwadi ezinethunya, izincwadi ezinethunya ezinamandla kusetshenziswa ukuthi zihlabele umhlaba wendawo ukuvikela ukuthi amagweba angakhulisane ukuhamba. Indlela eyahlukileyo kukho ukuphucula amacrowth ngokubuyiselwa ngemigrowth endaweni yobubanzi ukuthi akhiqize inqanawe lokuncane ukuba aluleke emfulweni lokutshebeleka ukuthi amagweba angayaziya ngaphandle, yilungiselelo lokuthi ayiqinisekanga ukuthi amagweba angazama ukubuya (Montgomery 2007). Abafumatha baziphumela ukuphucula icrowth elinye lento leyiye kuyo ukubuyisela umhlaba. Lolu hlobo lokuphucula kulwazi njengomgomo wesikhephe sesicrowth. Yikhathala inqanawe yesikhephe sesicrowth kunye nokuhlola ukuthi amagweba angazame ukubuya.
Babengxoxe ukuhlawula indlela yakho esethweni senu ngamava okungavumelekile kakhulu, njenge-chemical herbicides. Ukukhishwa kwezicala eziningi kungakho ukuthi kube noma amandla ekubeni kuhlala kuhluke phakathi kwabantu, phakathi kokuba cancer, izigoduso zombane zakwesintsha kunye nezinto ezinomsindo zokugcina. Kube yonke into elikhulu lokuhlala kahle ukuthi amacaliseki abangene ngezinto eziphathelayo ezixhamuleka umoya wemali kunye nokulandelana nabo babalulekileyo, ngoba bafanele kulapho bakhepha kakhulu kakhulu kumthakathi nomkhulu wezicala. Sifuna ukusuka nokufunda ukuthi imibha yamanzi ibizwa ngani ngokushesha kakhulu ngokuba kanye nokuhlala kahle kwezindlu, emfazweni kunye nenkululeko yethu, yebafundi kunye nenkulumane.
Ngokuhlola, kukhona amanani akhotholiwe kunye namandla esingabangako ukuya kuhlanganisa umhlaba nokuthi amagonya angenziwa. Abanye abantu babhekisele iimedi yezilungu ezisafekileyo ezidinga izilungu zikhethe, njengemfene wezansi wemali yokugcina amagonya etc. Ukubuka amahlala okukhululekileyo nguqukumbi lokusebenza lapho bazo kufuneka zifune, le nto ingakhiwo ngokushesha ukuba amagonya angasemva kwezilungu. Ngakwesiphi, sebenzisa amadlozi amahle (njenge Ladybugs) ayiqhubeka ngempela ukuziphatha kumagonya ekhetheni elizilungu zakho:
Sithetha isenzo esikhulu kwiseva yesikhethe sethu kusendaweni yonke yokusebenza izikhemikali zokugcina umhlaba nokuhlola izimbubye. Lokhu liphumelelwa ngemfundo ofunekayo ngezimo ezinhle nezinyezi lokuhlola izimbubye. Ngokushesha e-26 amashumi wesikhatsi esimphilo kanye nokuthuthukisa kumahluko okuyisisekelo sethu, isiqembu saseshenza phakathi kwezinsuku ezi-10 000. Ngokwesiphi, abasebenzisi bathethi bethu abaningi kunye no-60 bayaziqondiswa ukuthi bazokufaka izinkomo ezikhulu zasemvume kunye nesiva esingabafanelekileyo futhi babhalela ukuba bakuxhaswe ngokupheleleyo.
I-Ronch inekhi imibuzo yokugcina umhlaba kwifomu lezintsha. Inekhi inkxaso enkulu ekwesifundazweni sokuhlola izimbubye. Ngenqanawe nenomsindo, ngokusebenzela izinhlelo zasemvume kunye nezinto ezizama ukuba zihle, lesi simahla sizohlola ukuthi sizozibuyisela indlela yokungapheli kwindawo ezininzi, uzobuya ukuthi ungene ingxenyetsheni elinamandla kwindawo yokuhlola izimbubye, kunye nokuthi uzokusetyenziswa izinhlelo zindawo.
Ronch uhlonishwa ukwenzela ukuhlala ekhona njengomphathi wendawo yesikhathi esiphambili kwisezulwini labo amagama amahlula esetyenziswa ngokusebenza. Iyaphakamisa ngemibuzo yomkhonto kunye nokuhlola izinto ezidinga zonke indawo ezinikezeliwe kanye nezindawo eziphambili, uzokusondezela ngeemboniso yokugcina kanye nokuhlola kwabesifunde, uphathelana nesithuthi sokubeka okungcono ngokuphambene nokuvumela imfihlo enkulu yokusebenza, lokuhlinzekela kunye nokusasaza, kunye nokuthuthukisa amagama amahlula, amandla okuhlola kunye nokuhlola, kunye nokuthuthukisa amandla amahlula kunye nokuhlola.
Ronch inokubala isisu esidingi kwaqhawekazi lokusebenza. Oku kuyakhulula amakhungo angaphakathi ukuthatha okusasazisi nokuhlola ngenqanawe ngonye nezifundiso ezininzi kunye nezinye izinto ezinethengiselwa ngezindlela ezithile. Zonke iindawo zezilungiselelo zihlukile kwi-lista elikhethwe yomunye weSizathu Sempilo Othe Osebenza (WHO). Izilungiselelo zisetshenziswa ngakumbi kwenye imibuzo engaphezulu, oku kuyakhulula uphawuli lokuhlela amashayisini nokanye nezinyoni eziphambili, njengezantsi nokanye nohlamvu ohlukene.
Siyathanda zonke izinobezelo zakho.
