Ucwaningo lwakamuva lwesayensi lunikeza umbono oguquguqukayo ekulweni nokuguga kanye nezifo eziningi (kuhlanganise nomdlavuza): ukudla kancane, futhi okuncane kakhulu kunokujwayelekile.
Njengomphumela wokuhlolwa okwenziwe ngamagundane, kwatholakala ukuthi ngaphansi kwezimo zokuvinjelwa okunzima kokudla, umzimba uyakwazi ukushintshela kwenye imodi - empeleni, ukuzimela, ngenxa yalokho izakhi zamaseli omzimba wawo. zisetshenziswa, kufaka phakathi "okwesibili". Ngesikhathi esifanayo, umzimba uthola, njengokungathi, "umoya wesibili", futhi izifo eziningi, kuhlanganise nomdlavuza, zelashwa.
Ngaphambilini, odokotela babekholelwa ukuthi le nqubo yemvelo “yakhiwe” ngokuziphendukela kwemvelo ngokwemvelo ukuze kusindiswe zonke izilwane (kanye nabantu) ezikhathini ezinde zokushoda kokudla. Kodwa-ke, ukutholwa kwakamuva kodokotela base-Australia kunikeza ukukhanya okusha ngale ndlela yemvelo ebaluleke kakhulu engasetshenziselwa izinjongo zezempilo.
UDkt. Margot Adler weNyuvesi yaseNew South Wales (Australia), owayehola ithimba labacwaningi, uthe empeleni, isayensi isineminyaka engamashumi ambalwa isondela kulokhu kutholakala - phela, iqiniso lokuthi indlala noma ukuvinjelwa kokudla okunzima kuyaphilisa. umzimba futhi anganikeza ngisho nokuphila isikhathi eside akuyona izindaba kuzazi zezinto eziphilayo.
Nokho, ngaphansi kwezimo zemvelo, ngokusho kukaDkt. Adler, ukuvinjelwa kokudla akuholeli ekululameni nasekwandiseni ukuphila, kodwa ekuqothulweni, ikakhulukazi ezilwaneni zasendle. Esilwaneni esibuthakathaka ngenxa yendlala (nomuntu ohlala emvelweni), ukuzivikela kwehla kakhulu futhi isisindo semisipha siyancipha - okwandisa ingozi yokufa ngenxa yezifo kanye nezingozi ezihlukahlukene. “Ngokungafani nasendaweni yaselabhorethri eyinyumba, ngokwemvelo, izilwane ezibulawa indlala ziyafa ngokushesha, ngokuvamile ngaphambi kokuba zifike ekugugeni - ngenxa yezinambuzane noma emilonyeni yezinye izilwane,” kusho uDkt. Adler.
Le ndlela inikeza isikhathi eside kuphela endaweni yokwenziwa, "greenhouse". Ngakho-ke, uDkt. Adler uyakuphika ukuthi kungenzeka ukuthi lo mshini kuthiwa wakhiwe ngokwemvelo ukuze kuvinjelwe ukushabalala - ngoba endle awusebenzi nje. Ukholelwa ukuthi lokhu okutholakele kuyilabhorethri kuphela, "ukukhwabanisa kwempilo" yesimanje, indlela enhle yokuzungeza izingibe zemvelo kamama. Ukuhlola kwakhe kufakazele ukuthi ngaphansi kwezimo ezivikelwe, abantu abazila ukudla okulawulwayo bangelapheka umdlavuza, izifo ezihlukahlukene eziwuphawu lokuguga, futhi bamane bandise isikhathi sabo sokuphila.
Ngesikhathi sokuzila ukudla, uDkt. Adler wathola, indlela yokulungisa amangqamuzana nokuvuselela ivuliwe, okuholela ekuvuseleleni okukhulu nokuvuselela umzimba. Le phethini yabeka isisekelo sendlela esebenzayo: iziguli ezinomdlavuza zingafakwa ekudleni okunekhalori ephansi kakhulu esibhedlela; kuphinde kuhlelwe esikhathini esizayo esiseduze ukudala umuthi wokuzila ukudla okungenabuhlungu ngokusho kohlelo olukhethekile.
Imiphumela yalokhu kutholwa kwesayensi, okungasho lutho olungaphansi kokusungulwa kwenkolelo-mbono entsha yokuziphendukela kwemvelo, ishicilelwe kumagazini wesayensi i-BioEssays. “Lokhu kunamandla amakhulu empilweni yomuntu,” kusho uDkt. Adler. - Ukwenyuka kwesikhathi sokuphila, njengokungathi, umphumela wokunciphisa ukudla okunomsoco. Ukuqonda okujulile kokuthi lo mshini usebenza kanjani kusiholela ekwandeni kwangempela kokuphila isikhathi eside. ”
Sekuvele kusobala ukuthi inkolelo-mbono entsha, eqinisekisiwe ngokuhlolwa, inokusebenza okungokoqobo: ukulwa nokuguga ngaphambi kwesikhathi, ukwelashwa kwezifo ekugugeni, ukwelashwa kwamathumba abulalayo, izifo ezingapheli, kanye nokuthuthukiswa okujwayelekile komzimba onempilo enemibandela. Nakuba, bathi, “awukwazi ukuthenga impilo,” kuvela ukuthi usengakwazi ukuphila isikhathi eside futhi unempilo enhle uma sesikulungele ukuyeka imikhuba yethu yokudla, ososayensi baye bafinyelela kulesi siphetho.
Eqinisweni, lokhu kutholakala “kokuguquka” kwezazi zesayensi yezinto eziphilayo akukusha kwabadla imifino, abadla inyama, abadla ukudla okuluhlaza. Phela, siyazi ukuthi ngokudla ukudla okunamaprotheni amancane kakhulu nama-calories emini, umuntu ngeke “afe” kuphela (njengoba abanye abadla inyama abangakholwa bekholelwa), kodwa uhlangabezana nokwanda kwamandla nempilo, futhi azizwe emuhle – futhi hhayi nje usuku olulodwa noma ezimbili, neminyaka neminyaka.
Kuphephile ukucabanga ukuthi izinzuzo zokudla okungenanyama, okunekhalori ephansi, okunamaphrotheni aphansi kusazoqashelwa ekugcineni isayensi yesimanje kanye nokunqoba emphakathini omusha ozophila isikhathi eside, ngokuziphatha okuhle, ngenkuthalo, futhi unempilo.
