Impilo yezinhlelo zamanzi nomhlabathi weplanethi yethu ixhumene kakhulu nezinqubo zezolimo, futhi ukufuywa kwezilwane ezimbonini kunomthelela omubi kakhulu. Imfuyo emikhulu ikhiqiza imfucuza eningi, evame ukungena emifuleni, emachibini, namanzi angaphansi komhlaba, ingcolise imithombo yamanzi nge-nitrogen, i-phosphorus, imithi elwa namagciwane namagciwane. Lokhu kungcola kuphazamisa imvelo yasemanzini, kusongela impilo yabantu, futhi kunomthelela ekwandeni kwezindawo ezifile olwandle nasezindaweni ezihlala emanzini ahlanzekile.
Umhlabathi, isisekelo sokuvikeleka kokudla emhlabeni wonke, uhlupheka ngokulinganayo ngaphansi kokufuywa kwezilwane ngamandla. Ukudlisa ngokweqile, izitshalo zokuphakela i-monoculture, kanye nokuphathwa kabi komquba kuholela ekugugulekeni, ekuncipheni komsoco, nasekulahlekeni kokuvunda kwenhlabathi. Ukuwohloka kwenhlabathi engaphezulu akugcini nje ngokubukela phansi ukukhiqizwa kwezitshalo kodwa futhi kunciphisa amandla emvelo omhlaba okumunca ikhabhoni futhi alawule imijikelezo yamanzi, kuqinise kokubili isomiso nezikhukhula.
Lesi sigaba sigcizelela ukuthi ukuvikela amanzi nomhlabathi kubalulekile ekusimameni kwemvelo nempilo yabantu. Ngokugqamisa umthelela wokulima kwasefekthri kulezi zinsiza ezibalulekile, kukhuthaza ukushintshela ezindleleni zezolimo ezivuselelayo, ukuphathwa kwamanzi okunesibopho, kanye nokudla okunciphisa ubunzima kuzinhlelo zemvelo ezibalulekile zeplanethi yethu.
Ukufuywa kwemfuyo bekuyingxenye esemqoka yempucuko yabantu izinkulungwane zeminyaka, kuhlinzeka ngomthombo obalulekile wokudla nokuziphilisa emiphakathini emhlabeni jikelele. Kodwa-ke, ukukhula nokuqina kwale mboni emashumini eminyaka amuva nje kube nomthelela omkhulu empilweni nasekuhlukeni kwezinhlelo zemvelo zeplanethi yethu. Isidingo semikhiqizo yezilwane, esiqhutshwa ukwanda kwabantu kanye nokushintsha okuthandwayo kokudla, kuye kwaholela ekwandeni kokufuywa kwemfuyo, okuholela ekushintsheni okukhulu kokusetshenziswa komhlaba kanye nokucekelwa phansi kwezindawo zokuhlala. Lokhu kube nomthelela omkhulu ezinhlobonhlobo zezinto eziphilayo, njengoba kunezinhlobo eziningi zezinto eziphilayo ezibhekene nokushabalala kanye nemvelo eshintshwa ngendlela engenakulungiseka. Njengoba siqhubeka nokuthembela ekufuyweni ukuze siphile futhi sikhule komnotho, kubalulekile ukuhlola kanye nokubhekana nemiphumela yale mboni ekulahlekeni kwezinhlobonhlobo zezinto eziphilayo. Kulesi sihloko, sizohlola izindlela ezahlukene ukulima kwemfuyo kube nomthelela ngayo ekulahlekeni kwezinhlobonhlobo zezinto eziphilayo kanye nezixazululo ezingaba khona ...
