Iyi webhusaiti inoshandisa makuki kuti uve nechokwadi chekuti unowana ruzivo rwakanyanya paunenge uchibhurawuza.Kudzvanya "Tora" zvinoreva kuti unobvuma aya mazwi.
Vesainzi vari kuongorora mashandisirwo easbestos mumarara emigodhi kuchengetedza huwandu hwakawanda hwecarbon dioxide mumhepo kubatsira kugadzirisa dambudziko remamiriro ekunze.
Asbestos iminerari yechisikigo yaimboshandiswa zvakanyanya sekudzivirira kupisa uye kudzoreredza moto muzvivakwa.Aya mashandisirwo anozivikanwa zvakanyanya nekuda kwecarcinogenic zvimiro, asi akashandiswa mune mamwe mabhureki emota uye sirin'i uye mataira edenga muindasitiri yechlorine.Kunyange zvazvo nyika 67 dzichirambidza kushandiswa kwezvinhu zvefiber, United States haisi imwe yadzo.
Iye zvino, vatsvakurudzi vari kutarisa kune mamwe marudzi e-fibrous asbestos, ayo ari tsvina kubva kumigodhi.Sekureva kwaEos, iyo yakanyanya kunaka mhando inoita kuti asbestos ine ngozi pakufemerwa, zvakare inoita kuti ive yakashongedzerwa kubata kabhoni dhaikisaidhi zvidimbu zvinoyangarara mumhepo kana kunyungudika mumvura.Chirevo chinodonongodza kuti nzvimbo yakakwira yefiber inoita kuti ive "yakanyanya kuita uye nyore kushandura" kuita isingakuvadze kabhoni kana yakasanganiswa necarbon dioxide.Izvi zvinongoitika zvoga kana asbestos inoratidzwa kune greenhouse magasi.
Sekureva kweMIT Technology Ongororo, zvinhu zvakatsiga izvi zvinogona kuvharira magasi egreenhouse kwemamiriyoni emakore uye zvakaratidza kuve sarudzo inogoneka yekutora yakawanda yecarbon dioxide kubva mumhepo.Masayendisiti anotarisira kumisa "makuru" kabhoni kubva kumabasa emigodhi kutanga, uyezve kuwedzera kuedza kudzikisa kuburitswa kwegasi rinopisa.
Gregory Dipple, muongorori anotungamira mumunda, akaudza MIT Technology Ongororo: "Mumakore gumi anotevera, decarbonizing migodhi ichangotibatsira kuvaka chivimbo uye hunyanzvi kuitira kuderedza kuburitswa.Uye kucherwa chaiko kunoitwa.”
Sekureva kwaKottke Ride Home Podcast host Jackson Shiri (Jackson Shiri) akataura kuti kana zvinhu izvi zvapinda mugungwa kuburikidza nekuyerera, mineralization inoitikawo.Zvisikwa zvemugungwa zvinoshandisa maioni aya kuita kuti mateko nemapfupa azvo anozopedzisira ave limestone uye kumwe kubatwa.Carbon rock.
Carbon kuchengetedza inzira inodiwa yekudzikisa huwandu hwecarbon dioxide mumhepo.Pasina iyo, isu hatigone kuzadzisa "zvinangwa zvedu zvekabhoni" uye kudzivirira zvakaipisisa mhedzisiro yedambudziko remamiriro ekunze.
Vesainzi vari kuongororawo mashandisirwo emarara kubva kune mamwe maindasitiri emigodhi akaita senickel, mhangura, madhaimondi neplatinamu kubata kabhoni.Vanofungidzira kuti panogona kunge paine zvinhu zvinokwana kumisa carbon dioxide yese yakamboburitswa nevanhu, nezvimwe zvakawanda, Shiri inoshuma.
Ikozvino, zvinhu zvizhinji zvakagadzikwa mumatombo akasimba asina kumbobvira aonekwa nemhepo, izvo zvinotanga iwo magadzirirwo emakemikari.Ichi ndicho chikonzero masayendisiti ari kudzidza kubvisa kabhoni ari kuyedza kutsvaga nzira dzekuwedzera kuratidzwa uye nekumhanyisa iyi inononoka mhinduro kuitira kushandura marara emigodhi kuita mutsigiri ane simba wekupokana nedambudziko remamiriro ekunze.
Chirevo cheMIT chinodonongodza kuti mapindiro mangani akaedzwa nekuchera zvinhu, kuzvikuya kuita zvidimbu zvakatsetseka, obva azviparadzira kuita zvidimbu zvitete, obva azviparadzira nemhepo kuwedzera kuratidzwa.Zvimwe zvinoda kudziyisa kana kuwedzera asidhi kumukomboni.Eos inoshuma kuti vamwe vanotoshandisa matinji ebhakitiriya kutanga kuita kwemakemikari.
"Tiri kutsvaga kukurumidzira kuita uku uye kuishandura kubva murwi wemarara easbestos kuita dhipoziti isingakuvadzi," akadaro geomicrobiologist Jenine McCutcheon, akazvipira kushandura miswe yeasbestos yakasiiwa kuita isingakuvadzi Magnesium carbonate.Gymnasts uye vanokwira matombo vanoshandisa zvinhu zvichena zvehupfu kuvandudza kubata.
Roger Aines, director weCarbon Program kuLawrence Livermore National Lab, akaudza MIT Technology Ongororo kuti: "Uyu Mukana muhombe, usina kugadzirwa, unogona kubvisa kabhoni dioxide yakawanda."
Chirevo ichi chinoenderera mberi ichiti vanotsigira zano idzva vanonetsekana nemitengo uye zvirambidzo zvevhu.Zvichienzaniswa nedzimwe nzira dzekudzikira dzakadai sekudyara miti, nzira iyi inodhura.Zvingangodawo nzvimbo yakakura kuti iparadzire zvinhu zvitsva zvakafukunurwa zvakakwana kuderedza zvakanyanya kuburitsa kabhoni, zvichiita kuti zviome kukwira.
Shiri yakataurawo kuti maitiro ese anogona kupedza simba rakawanda, uye kana akasanyatsoyerwa, anogona kumisa mabhenefiti ekutora kabhoni aari kuyedza kugadzira.
Chekupedzisira, pane zvakawanda zvinonetsa zvakatenderedza kuchetura kwezvinhu izvi uye kuchengetedzeka kwekuzvibata.The MIT Technology Review yakaratidza kuti kuparadzira guruva reasbestos pasi uye / kana kupararira muguruva kuti kuwedzere kutenderera kwemhepo kwakakonzera njodzi dzekuchengetedza kune vashandi vari pedyo nevagari vemo.
Shiri akagumisa kuti zvisinei neizvi, chirongwa chitsva ichi chinogona kunge chiri "sarudzo inovimbisa yekuwedzera dzimwe mhinduro dzakawanda, nekuti tese tinoziva kuti hapazove nekugadzirisa dambudziko remamiriro ekunze."
Kune zviuru zvezvigadzirwa kunze uko.Vanhu vazhinji vanozoita chinhu chimwe chete, kana kuti zvakangofanana, asi nekusiyana kwakajeka.Asi zvimwe zvigadzirwa zvine chepfu inogona kukuvadza isu kana vana vedu.Kunyange basa riri nyore rekusarudza mushonga wemazino rinogona kuita kuti tizvidye mwoyo!
Mimwe mhedzisiro yemamiriro ekunze akanyanya inogona kuoneka-semuenzaniso, hafu yechibage chakatsetseka muIowa yakasiiwa mushure mekunge Midwestern United States yakarohwa zvakanyanya muna Nyamavhuvhu 10.
