Unobangela wokugawulwa kwamahlathi emhlabeni

Ukutshatyalaliswa kwamahlathi

Ukwandiswa kwezolimo ngoyena nobangela uphambili we ukugawulwa kwamahlathi emhlabeni. Ukutyalwa kwe-oli yesundu, ukukhula kwezityalo zokondla izilwanyana, ukumbiwa kwesinyithi kunye neeminerali ezixabisekileyo zezona zinto zibangela ukutshatyalaliswa kwamahlathi. Uninzi lwamafama amancinci ahluphekayo kwaye ahambahambayo nawo athatha inxaxheba ekutshatyalalisweni kwamahlathi, kuba ayatshisa amahlathi ukubanakho ukuhlwayela umhlaba omncinci.

Umzekelo, ngaphakathi Brasil, amahlathi aphambili atshatyalalisiwe ukukhulisa iimbotyi zesoya ezondla imfuyo, kunye nommoba ukuvelisa i-bioethanol, ngelixa Indoneshiya, amasimi ayagawulwa ukuze kutyalwe imithi yesundu evelisa i-oyile, ethi izikhusele iimveliso zevenkile ezinkulu kwaye inokondla iimoto kungekudala.

La ukwandiswa kwezolimo ikwasisiphumo sokwanda kwenani labemi behlabathi.

Ukukhutshwa kwezibaso

Okokugqibela, ukukhutshwa kwe petroleum kunye negesi ikwadlala indima ekubeni amahlathi amakhulu onakalisiwe kukuxhatshazwa nokubekwa kwemibhobho yeoyile, singasathethi ke ngokuvuza rhoqo kweoyile okanye ukuxhaphaza iisanti zetela.

Ukugawulwa ngokungekho mthethweni

La ukuxhaphaza akukho mthethweni iinkuni zikwadlala indima ebalulekileyo ekugawulweni kwamahlathi. IYurophu inembopheleleko enkulu kolu hlazo, kuba malunga nekota yokungeniswa kwamaplanga kwamanye amazwe ivela kwimithombo engekho mthethweni. Kuqikelelwa ukuba phakathi kwe-50 kunye ne-90% yokuxhatshazwa kwamahlathi kumazwe aphambili ashushu eAmazon, kuMbindi weAfrika nakuMzantsi-mpuma Asia, kuvela kulwaphulo-mthetho olulungelelanisiweyo.

Ukuphulukana kwendalo

Los amahlathi babamba ngaphezulu kwama-80% ezinto eziphilayo ezisemhlabeni kwaye babonisa enye yeendawo zokugqibela zokugcina izilwanyana kunye neentlobo zezityalo. Ngesi sizathu, ukugawulwa kwamahlathi kuyintlekele emntwini nakwezinye iintlobo, kuba kuqikelelwa ukuba zingama-27.000 iintlobo zezilwanyana nezityalo ezithi shwaka nyaka ngamnye ngenxa yokutshatyalaliswa kwemithi. Oku kulahleka kwe izinto ezahlukeneyo zenzululwazi, ezingenakuphikiswa, zibunciphisa ubuntu kwiinkonzo kunye nezixhobo ezingabalulekanga. Ewe, iinkqubo zokutya zixhomekeke kakhulu kwiyantlukwano yendalo, kwaye uninzi lwamayeza ayimvelaphi yebhayiloji.

    Inqaku elihle.
    Ndingacacisa imveliso ye-biofuels, eyathengiselwa thina njengesiqhelo sendalo kwaye ekugqibeleni yayingeyiyo.
    Ngoku yioyile yesundu.
    Kwaye okoko, ezolimo nemfuyo zezona zinto zingunobangela wokutshatyalaliswa kwamahlathi.
