<prompt> Fingqa isihloko: Kulabo abanethemba lokuthi ukufudumala kwembulunga yonke kuzoletha amathuba engeziwe okwenza i-barbecue yasehlobo, kungase kube nokudumazeka okuzayo - ukuguquka kwesimo sezulu cishe kuzokwenza ama-steak nama-burger angabi mnandi kangako. Embikweni omkhulu ophathelene nethonya lokufudumala kwembulunga yonke ekudleni, ososayensi baye baphetha ngokuthi izinga lenyama nemifino eminingi liyancipha ngenxa yokwenyuka kwamazinga okushisa. Abacwaningi babikezela ukuthi njengoba amagagasi okushisa eba avamile, ama-steak nezinye izinhlobo zenyama cishe ziyoba nemicu eminingi futhi zibe lukhuni - okubeka i-barbecue yendabuko engozini. Ama-beefburgers, njengalawo angenhla, angaba inketho engathandeki kangako kuma-BBQ esikhathi esizayo ngenxa yokuguquka kwesimo sezulu. Imifino ethandwayo njengama-karoti nayo cishe ngeke isakunambitheka kahle futhi ngeke ibe mnandi. Kungenzeka ukuthi amazambane ahlushwa kakhulu isifo sokugqwala, esibola amahlumela awo futhi siwenze angadliwa. Izazi zesayensi yezinto eziphilayo zasolwandle ziye zathola ukuthi izimfanzi ziba nokunambitheka okumuncu uma zikhuliswa emanzini asolwandle ane-asidi encane. Baxwayisa ngokuthi njengoba ulwandle lomhlaba luba ne-asidi, ngenxa yokwanda kwamazinga e-carbon dioxide, ukudla kwasolwandle esikuthandayo kungase kungabi mnandi kangako. Ochwepheshe bokushintsha kwesimo sezulu babikezela ukuthi phakathi nekhulu leminyaka elizayo, amazinga e-asidi olwandle lomhlaba wonke angase ehle asuke ku-pH8 aye ku-pH7.5. Abaningi baye baxwayisa ngokuthi lokhu kungase kuholele ekutheni izimfanzi nemikhaza kube nzima ukwakha amagobolondo namathambo eziwadingayo ukuze ziphile. Manje, ocwaningweni lokuqala lokuhlola ukuthi ukwanda kwe-acidification olwandle kungathinta kanjani ukunambitheka kokudla kwasolwandle, abacwaningi baseYunivesithi yaseGothenberg naseYunivesithi yasePlymouth, bathola ukuthi nakho kuyokuthinta ukunambitheka kwabo. Izinhlanzi ezikhuliswe emanzini ane-pH ephansi zazinamathuba aphindwe izikhathi ezingu-2,6 okubhekwa njengezinambitheka ezimbi kakhulu, kuyilapho lezo ezikhuliswe emanzini ane-asidi encane zazinamathuba aphindwe izikhathi ezingu-3,4 okubhekwa njengezinambitheka kakhulu. U-anyanisi angase abe mncane uma amazinga okushisa enyuka ekuqaleni kwesizini kuyilapho izihlahla zezithelo nezamantongomane kwezinye izindawo zingase zingabandi ngokwanele ukuba zibonise ukukhula kwezithelo. Lombiko, owakhiqizwa ososayensi baseYunivesithi yaseMelbourne, wabuye waxwayisa ngokuthi ubisi...  <response>: Umbiko weNyuvesi yaseMelbourne uxwayisa ngokuthi ukudla okuningi kusengozini. Lithi amagagasi okushisa ayokwenza imfuyo njengenkomo ihlupheke ngenxa yokushisa. Inyama yenkomo nengulube cishe iyoqina kakhulu kuyilapho inkukhu iyoqina kakhulu. Izitshalo zika-anyanisi nobhontshisi zingase zikhiqize imifino emincane. Izaqathe ziyolahlekelwa ukunambitheka kwazo okuyingqayizivele futhi zithole ukwakheka okungathandeki. Imikhiqizo yobisi ingancipha ngamaphesenti angu-10 kuya kwangu-25 phakathi namagagasi okushisa, kuxwayisa umbiko. Amazinga amaprotheni obisi nawo angehla okusho ukuthi ushizi uzokwehla ngekhwalithi.
