Iphephandaba laseBrithani elidumile nelihlonishwayo i-Guardian lanyathelisa imiphumela yocwaningo lwamuva nje olungabizwa ngokuthi luyaxaka futhi luyacindezela ngesikhathi esifanayo.
Iqiniso liwukuthi ososayensi bathole ukuthi izakhamuzi ezivamile ze-Foggy Albion ngesikhathi sokuphila kwakhe azigcini nje ngokumunca izilwane ezingaphezu kuka-11.000: izinyoni, imfuyo nezinhlanzi - ngendlela yemikhiqizo ehlukahlukene yenyama - kodwa futhi ngokungaqondile kunomthelela ekubhujisweni kwezwe. imvelo. Phela izindlela zesimanje zokukhulisa imfuyo azikwazi ukubizwa ngokuthi ziwubuqaba maqondana neplanethi. Iqatha lenyama epuletini akuyona nje isilwane esihlatshiwe, kodwa futhi namakhilomitha omhlaba osuphelile, ocekelwe phansi, futhi - njengoba ucwaningo lubonise - izinkulungwane zamalitha amanzi aphuzwayo. “Ukuthanda kwethu inyama kuyonakalisa imvelo,” kusho i-Guardian.
Ngokusho kwe-UN, okwamanje cishe abantu abayizigidi eziyizinkulungwane ezingu-1 emhlabeni bangondlekile njalo, futhi ngokusho kwezibikezelo zenhlangano, eminyakeni engu-50 lesi sibalo sizophindeka kathathu. Kodwa inkinga futhi ukuthi indlela labo abanokudla okwanele abadla ngayo iqeda imithombo yomhlaba ngezinga eliyinhlekelele. Abahlaziyi bathole izizathu ezimbalwa eziyinhloko zokuthi kungani isintu kufanele sicabange ngemiphumela yemvelo yokudla inyama kanye nethuba lokukhetha enye indlela “eluhlaza”.
1. Inyama inomphumela obamba ukushisa.
Namuhla, iplanethi idla amathani angaphezu kuka-230 enyama yezilwane ngonyaka - kabili kunaseminyakeni engama-30 edlule. Ngokuyisisekelo, lezi izinhlobo ezine zezilwane: izinkukhu, izinkomo, izimvu nezingulube. Ukuzalanisa ngamunye wabo kudinga inani elikhulu lokudla namanzi, futhi imfucumfucu yabo, enqwabelanisa izintaba ngokoqobo, ikhipha i-methane namanye amagesi abangela umphumela wokushisa esikalini seplanethi. Ngokocwaningo lweNhlangano Yezizwe ka-2006, umphumela wesimo sezulu wokukhulisa izilwane ukuze uthole inyama udlula umthelela omubi eMhlabeni wezimoto, izindiza kanye nazo zonke ezinye izindlela zokuthutha zihlangene!
2. Indlela ‘esiwudla’ ngayo umhlaba
Inani labantu emhlabeni likhula kancane kancane. Umkhuba ovamile emazweni asathuthuka uwukudla inyama eningi njalo ngonyaka, futhi lesi samba siphindeka kabili okungenani njalo ngemva kweminyaka engu-40. Ngesikhathi esifanayo, lapho ihunyushwa emakhilomitha esikhala esabelwe ukuzalanisa imfuyo, izinombolo zihlaba umxhwele nakakhulu: phela, kuthatha indawo ephindwe izikhathi ezingu-20 ukondla inyama edla inyama kunomuntu odla imifino.
Kuze kube manje, kakade amaphesenti angu-30 omhlaba, ongamboziwe ngamanzi noma iqhwa, futhi alungele ukuphila, ahlala ngokufuya imfuyo. Lokhu sekuvele kuningi, kodwa izinombolo ziyakhula. Akungabazeki nokho ukuthi ukufuya kuyindlela engasebenzi kahle yokusebenzisa umhlaba. Phela, uma kuqhathaniswa, ngokwesibonelo, e-United States namuhla, amahektha ayizigidi ezingu-13 anikezwe izitshalo zokulima (imifino, okusanhlamvu nezithelo), namahektha ayizigidi ezingu-230 okufuya. Inkinga ibhebhethekiswa wukuthi iningi lemikhiqizo yezolimo elinywayo ayidliwa ngabantu, kodwa idliwa yimfuyo! Ukuze uthole i-1 kg yenkukhu ye-broiler, udinga ukondla u-3.4 kg wokusanhlamvu, i-1 kg yengulube "idla" kakade i-8.4 kg yemifino, kanti ezinye izilwane "zenyama" azinamandla kangako, ngokudla kwemifino. ukudla.
3 . Izinkomo ziphuza amanzi amaningi
Ososayensi baseMelika babale: ukuze ukhule ikhilo lamazambane, udinga amalitha angama-60 amanzi, ikhilogremu kakolweni - amalitha ayi-108 amanzi, ikhilogremu lommbila - amalitha ayi-168, kanye nekhilogremu yerayisi izodinga amalitha angama-229! Lokhu kubonakala kumangalisa kuze kube yilapho ubheka izibalo zemboni yenyama: ukuze uthole i-1 kg yenkomo, udinga amalitha angu-9.000 amanzi ... Ngisho "nokukhiqiza" i-1 kg yenkukhu yenkukhu, udinga amalitha angu-1500 amanzi. Uma kuqhathaniswa, ilitha elingu-1 lobisi lizodinga amalitha ayi-1000 amanzi. Lezi zibalo ezihlaba umxhwele ziphaphathekile uma ziqhathaniswa nezinga lokusetshenziswa kwamanzi yizingulube: ipulazi lezingulube eliphakathi nendawo elinezingulube ze-80 lidla cishe amalitha ayizigidi ezingu-280 zamanzi ngonyaka. Ipulazi lezingulube elikhulu lidinga amanzi amaningi njengenani labantu bedolobha lonke.
Kubonakala sengathi izibalo ezijabulisayo uma ungakunaki ukuthi ezolimo kakade namuhla zisebenzisa u-70% wamanzi asetshenziswa abantu, futhi uma kunemfuyo eningi emapulazini, izimfuno zabo zizokhula ngokushesha. Amanye amazwe anothile ngezinsiza kodwa antula amanzi njengeSaudi Arabia, Libya kanye ne-United Arab Emirates asebalile ukuthi kunenzuzo enkulu ukutshala imifino nemfuyo emazweni asathuthuka bese ungenisa…
4. Ukufuya imfuyo kucekela phansi amahlathi
Amahlathi emvula asengozini futhi: hhayi ngenxa yezingodo, kodwa ngenxa yokuthi iziqhwaga zezolimo zomhlaba ziyawagawula ukuze kukhululwe izigidi zamahektha okuklama nokutshala ubhontshisi wesoya namasundu ukuze kutholwe amafutha. Ngokocwaningo lwakamuva olwenziwe ngabangane bomhlaba, cishe amahektha ayizigidi eziyisi-6 zamahlathi ashisayo ngonyaka - yonke indawo yaseLatvia, noma iBelgium ezimbili! – “impandla” bese kuba ipulazi. Ngokwengxenye lo mhlaba ulinywa ngaphansi kwezitshalo ezizophakelwa imfuyo, futhi ingxenye isebenza njengamadlelo.
Lezi zibalo, yiqiniso, zibangela ukucabangela: liyini ikusasa leplanethi yethu, yiziphi izimo zemvelo lapho izingane zethu nabazukulu bayohlala khona, impucuko ibheke kuphi. Kodwa ekugcineni, wonke umuntu uyazikhethela.
