Ukunwetshwa kwezolimo kuyimbangela enkulu ye- ukugawulwa kwamahlathi emhlabeni. Ukutshalwa kwamafutha esundu, ukuthuthukiswa kwezitshalo zokondla izilwane, ukumbiwa kwezinsimbi namaminerali ayigugu, yizimbangela ezinkulu zokuqothulwa kwamahlathi. Abalimi abaningi abampofu nabahambahambayo nabo babamba iqhaza ekuqothulweni kwamahlathi, ngoba kuyasha amahlathi ukwazi ukutshala iziqephu zomhlaba ezincane.
Isibonelo, ku Brasil, kubhujiswa amahlathi ukuze kutshalwe ubhontshisi odlisa imfuyo, nomoba ukukhiqiza i-bioethanol, ngenkathi Indonesia, kususwa izihlahla ukuze kutshalwe izihlahla zesundu ezikhiqiza uwoyela, ezigcwala imikhiqizo yezitolo ezinkulu futhi ezingaphakela izimoto.
La ukunwetshwa ezolimo kubuye kube ngumphumela wokwanda kwenani labantu emhlabeni.
Ukukhishwa kwamafutha ezimbiwa phansi
Ekugcineni, ukukhishwa kwe- i-petroleum kanti negesi nayo ibambe iqhaza njengoba izingxenyana ezinkulu zehlathi zilinyazwa ukuxhashazwa nokufakwa kwamapayipi kawoyela, ingasaphathwa eyokuvuza kukawoyela noma ukuxhashazwa kwesihlabathi setiyela.
Ukugawula okungekho emthethweni
La ukuxhashazwa ngokungemthetho izinkuni nazo zidlala indima ebalulekile ekuqothulweni kwamahlathi. IYurophu inesibopho esikhulu kulokhu kululazeka, ngoba cishe ingxenye yesine yokungeniswa kwayo ngokhuni kuvela emithonjeni engekho emthethweni. Kulinganiselwa ukuthi phakathi kuka-50 no-90% wokuxhashazwa kwamahlathi emazweni abalulekile asezindaweni ezishisayo e-Amazon, eCentral Africa naseNingizimu-mpumalanga ye-Asia, kuvela ebulelesi obuhleliwe.
Ukulahleka kwezinhlobonhlobo zezinto eziphilayo
I-Los amahlathi basingatha ngaphezu kwama-80% wezinhlobonhlobo zezinto eziphilayo ezisemhlabeni futhi bamele enye yezindawo zokugcina ezinde zezinhlobo eziningi zezilwane nezitshalo. Ngalesi sizathu, ukugawulwa kwamahlathi kuyinhlekelele kokubili kumuntu nakwezinye izinhlobo, ngoba kulinganiselwa ukuthi izinhlobo zezilwane nezitshalo ezingama-27.000 ziyanyamalala unyaka nonyaka ngenxa yokucekelwa phansi kwezihlahla. Lokhu kulahleka kwe- eziphilayo, okungenzeka kungalungiseki, kunciphisa ubuntu emisebenzini nasezinsizakalweni eziyigugu. Ngempela, amasistimu okudla ancike kakhulu ekuhlukeni kwezinto eziphilayo, futhi ingxenye enkulu yemithi ivela kokuphilayo.
Indatshana enhle.
Ngingakuqhakambisa ukukhiqizwa kwama-biofuels, athengiselwe thina njengomkhuba wezemvelo futhi ekugcineni akubanga njalo.
Manje sekungamafutha esundu.
Futhi kusukela njalo, ezolimo nemfuyo bekuyizimbangela eziyinhloko zokuqothulwa kwamahlathi.
