Ukukhetha Phakathi KwamaBhodi Okusika Amapulangwe Noma Amaplastiki Akuyona i-No-Brainer
Umfundi ocabangelayo wangithumelela ngomusa indaba ethakazelisayo yokusika amabhodi. Ishicilelwe okokuqala kuyi- Science News ka-Feb. 6, 1993, lesi sihloko sichaza ucwaningo oluchaza ukuthi amabhodi okusika izinkuni anesakhiwo esithile sokubulala amagciwane, ngaleyo ndlela angenzeki ukuthi angcolise ukudla kunamapulangwe epulasitiki noma ama-acrylic. "Ama-pathogens akhetha ipulasitiki," kusho lesi sihloko.
Nokho, eminyakeni engaba ngu-20 kamuva, ochwepheshe basakhuthaza amabhodi okusika amaplastiki, futhi iminyango yezempilo yendawo iyaqhubeka nokuvimbela ukusetshenziswa kwamapulangwe okusika izinkuni endaweni yokudla yokuthengisa.
Ngakho kwenzekani? Ukufunda ngokucophelela lesi sihloko kwembula ukuhlukaniswa phakathi kwalokho abacwaningi abakubonile kanye neziphetho abazithola kulowo mbono. Isibonelo esihle sokuthi kungani kungeke kube nomqondo omuhle ukuvumela omunye umuntu enze ukucabanga kwakho ngawe - ngoba ososayensi benza amaphutha njenganoma ubani omunye.
Ingabe Ama-Pathogens Afuna Amabhodi Okusika Ama-Plastic noma Izinkuni?
Lesi simangalo sisekelwe ekuhlolweni lapho amabhodi okusika izinkuni aphethwe yizifo ezivamile zokudla futhi avunyelwe ukuhlala ubusuku bonke. Ngakusasa ekuseni, abacwaningi bathola ukuthi "amaphesenti angu-99,9 amabhaktheriya ayengabonakali futhi kuthiwa afile."
Kubonakala sengathi ufile? Lokhu kuqhuma kakhulu, ikakhulu uma, ngokungenwa kwabacwaningi, "Asizange sithole izidumbu ezincane." Bavumela ukuthi kungenzeka ukuthi, esikhundleni sokufa, "abahlungi" bangase babalekele ngaphakathi kwezinkukhu kanye nemigqomo yezinkuni ezivuthayo, lapho bebezokhululeka khona ukuzala njengaye - njengamabhaktheriya.
Futhi njengoba siyazi ukuthi amabhaktheriya angaphila ebhodini lokusika kuze kufike emahoreni angu-60, lelo bhodi lokusika izinkuni lingabamba i- colony yonke yezinambuzane ngaleso sikhathi. "Njengombana singakghona ukutshela, lokho angeke kwenzeke," omunye wesosayensi wathi, nangabe akhenge acacise ukuthi kungani engacabangi ukuthi kuzokwenzeka.
Ngokuqondene nokuthi imishini noma i-ejenti kungenzeka yini ibhekene namandla okuphikisana okuphikisana namapulangwe, abacwaningi bavuma ukuthi babengazi lutho. Omunye uqala ukubona ukuthi kungani lesi sigaba esithi "isayensi" asizange siphumelele iminyango ekucabangeni okuvamile ngokuphepha kokudla .
Kodwa ekugcineni, umqaphi: Omunye wezinhlamvu ezincane ezinomthwalo wokucubungula uhlanganyela ngamasu akhe anconywayo ekuhlanza amapulangwe okusika izinkuni: "I-aipe enhle izokwenza kahle - futhi uma ukhohlwa ukusula ibhodi, cishe ngeke ube mabi kakhulu off. "
Kodwa uma ufuna amaqiniso wangempela ekunqumeni amabhodi, hlola lesi sihloko mayelana nokusika amabhodi nokuphepha kokudla .
