I-Gmos Thatha izityalo kunye nokuzaliswa kwezilwanyana kwiNqanaba elihlukileyo
Xa oososayensi basebenzisa ubunjineli bezakhi zofuzo ukuguqula iizakhi zendalo, ngokubanzi bafuna ukongeza umxholo abawujonga njengenzuzo, ngokubanzi ngenjongo yokuvelisa. Ngokuqhelekileyo, ubunjineli bezakhi zofuzo zenziwa ukufezekisa umgangatho ongekho ngokuqhelekileyo obanjwe ngumzimba, njengobomi obude obude, ukuxhatshazwa kwezifo okanye imibala eyahlukeneyo.
Ingozi kunye neenzuzo ze-GMO zixutyushwa kakhulu, kodwa ukuguqulwa kwemfuza okwangoku kuvunyelwe kwifama eqhelekileyo. Enyanisweni, imibutho kunye nezifundo ezininzi ziqikelelwa ukuba mhlawumbi i-70% okanye ngaphezulu kwazo zonke ukutya ezicwangcisiweyo ezithengiswa kubaxhasi ngoku ziqulethe izithako eziguqulweyo.
Njengoko limi ngoku ngoku, nayiphi into yokutya eqinisekisiwe yendalo ayinakuqulatha izithako eziguqulwa ngokwemizimba .
Kutheni Kutheni Ukuguqulwa Kwegazi Kukuguqula Izinto Eziphilayo?
Kwiiminyaka ezigidi, abalimi baye bafuna ukukhulisa izityalo okanye izilwanyana ezilwanyana ezinqwenelekayo. Amafama aqala ukukhetha imbewu kwizityalo zazo ezintle kakhulu njengesiqhamo sityalo sonyaka ozayo kwaye bakhetha izilwanyana zabo ezilungileyo ukuba zizalise kwaye zivelise esinye isizukulwana.
Ngokuhamba kwexesha kunye nolwazi olwandisiweyo lwezityalo nezityalo zezilwanyana, lo mkhuba waba yinkimbinkimbi, kwaye amafama kunye nososayensi baqala ukukhetha ngokukhethekileyo iimpawu ababezifuna. Baye baqala ukudala izilwanyana ezintsha zezityalo kwi-laboratory, ngokuchasene naso nasentsimini nokusebenzisa iikhemikhali kunye nemisebe emzame ukuguqula ukuveliswa kwezityalo kunye nokwenza utshintsho olufunwayo.
Le migudu iye yabangela iintlobo zezityalo ezahlukeneyo, kuquka iimizi zerayisi ezichasene nesomiso neengqolowa zengqolowa ezinokuvelisa kakhulu.
Ii-GMO zenza le migudu ukuya kwelinye iqanaba: endaweni yokusebenzisa ubuchwepheshe bebhabhi ukunyusa utshintsho oluhambisa iimpawu ezifunwayo, izazi ze-GMO zihlela ngokuthe ngqo ikhowudi yesityalo okanye yezilwanyana kunye nokufaka iigleji ezithwala loo mpawu.
Imizekelo ye-GMO Foods
Mhlawumbi umzekelo owaziwa kakhulu wesidlo se-GMO yi-Roundup Ready ngqolowa, iindidi ezahlukahlukeneyo ezenziwe nguMantanto Inkampani engamelana ne-herbicide glyphosate. Ukuxhatshazwa kwe-GMO-bred gsphosate (ephuma kwongezwa kwe-gene gene) ivumela abalimi ukuba basebenzise ngakumbi utywala, olwenziwe nguMonsanto, kwimimandla yabo equle ingqolowa.
I-Monsanto nayo idale i-Roundup Ready soy, i-alfalfa, i-canola, i-cotton, ne-sorghum. Ukongezelela, inkampani ine-corn, i-soybe, kunye nekotoni eguqulwa ngokwemizimba ukuze ivelise iigleji ezenza ezo zityalo zixhomekeke kwiinambuzane.
Ezinye iinkampani zihlakulela izilwanyana eziguqulwa ngokwemfuza. Umzekelo, i-salmon ye-AquAdvantage, i-salmon e-Atlantic eguqulwa ngokwemizimba eyakhiwe yi-AquaBounty Technologies kwaye yavunwa ngo-2015 yi-US Food Administration and Drug Administration ukuthengiswa e-US, ifaka iiglethi kwezinye iintlanzi, kuquka i-sinoon ye-Chinook. Ezi zakhi zenza ukuba i-salmon ye-AquAdvantage ikhule kabini ngokukhawuleza njengoko i-salmon e-Atlantic ingaguqukanga.
Ukhuseleko lwe-GMO luxutyushwa kakhulu. Abavelisi beemveliso eziqulethe ii-GMO bathi i-organisms ikhuselekile, kwaye i-arhente karhulumente ejongene nokukhusela ukubonelelwa kokutya kuvumile, kodwa amaqela abathengi aphikisa ukuba ii-GMO zidibaniswe nokudityaniswa kwezilwanyana kunye nezinye, ezinokubaluleke kakhulu, imicimbi yezempilo.
