Ke Leoatle la Pacific le Silafetseng

Ho qhalloa ha metsi a silafetseng a nyutlelie a Majapane Leoatleng la Pacific ke ntho ea sebele e ke keng ea fetoha, 'me ho ea ka morero oa Japane, e lokela ho tsoela pele ho ntšoa ka lilemo tse mashome. Qalong, mofuta ona oa tšilafalo ea tikoloho ea tlhaho e lokela ho nyatsuoa ke bohle ba ratang bophelo le tlhaho. Leha ho le joalo, ka lebaka la ho ameha ha lithahasello tse ngata, saense le bophelo bo botle li boetse li koeteloa ke chelete le lithahasello.

Ho ea ka tataiso ea metsi a leoatle a Leoatle la Pacific Leboea, metsi a silafetseng a nyutlelie a tla tloha Japane 'me a hoholehe ka bochabela haufi le Kuroshio e phallelang leboea lebōpong le ka bochabela la Japane, hammoho le phallo e phallang ka boroa ho tloha Arctic. E tla tšela Leoatle la Pacific kaofela ’me e fihle haufi le California, USA, ’me e phallele nģ’a leboea e lebile Canada haufi le moeli o pakeng tsa United States le Canada, e lateloe ke Alaska, Leoatle la Bering, le Hloahloeng ea Kamchatka ea Russia.

Kamora ho bala tsela ena, o ka utloisisa hore na ke hobaneng ha Mopresidente oa Korea Boroa a ts'ehetsa ka mokhoa o sa hlajoeng ke lihlong ho tsoa ha likhoerekhoere tsa nyutlelie tsa Japane, hobane tsela ea ho lahla e lebile Leoatleng la Pacific ka bochabela, eseng Leoatle la Japane ho ea bophirima. Korea Boroa e tla ba eona ea ho qetela le e silafetseng hanyane.

Batho ba bang ba re Mokhatlo oa Machaba oa Matla a Athomo ha o re morero oa Japane oa ho ntša metsi a litšila a nyutlelie o lumellana le litekanyetso tsa machaba tsa tšireletso? Leha ho le joalo, ka nako ea sebele, Setsi sa Machaba sa Matla a Athomo ha se na litekanyetso tsa ho qhalloa ha metsi a litšila a nyutlelie ka leoatleng, ke litekanyetso tsa machaba feela tsa ho qhalloa ha metsi a litšila a nyutlelie ka leoatleng.

II Liphello tsa Tšilafalo ea Maoatleng United States

Batho ba bangata ba makatsoa ke hore libaka tse silafetseng ka ho fetisisa ntle le maoatle a potolohileng Japane ke United States le Canada, empa ho bonahala eka ha ba utloe khanyetso ea tsona. Sebakeng seo, kopano e neng e tšoaretsoe Camp David naheng ea United States mafelong a khoeli ena e tla khothaletsa tlhahiso ea likhase tsa Japane. Tšilafalo ea leoatle ke batho e ’nile ea tsoela pele ka nako e telele, ’me ho sekisetsa ha lithahasello, chelete, le matla ke mekhatlo e meng ea machaba le ea lichaba e ’nile ea e-ba ntho e tloaelehileng ka nako e telele. U se ke ua nka hore Europe le Amerika li na le litokelo tsa sebele tsa botho le hore ntho e 'ngoe le e 'ngoe e itšetlehile ka lithahasello tsa batho ba bona.

Ka April 2010, BP UK e ile ea phatloha sethaleng sa eona sa ho cheka oli e tebileng leoatleng Koung ea Mexico, e ileng ea fella ka lefu la batho ba 11 le libarele tse limilione tse 4.9 tsa oli tse luthelang ka leoatleng. Ho feta moo, ho ile ha sebelisoa lilithara tse limilione tse 2 tsa li-agent tse senyang lik'hemik'hale, tse kang petroleum decomposition le 2-butoxyethanol. Lintho tsena tse senyang ke khale li "mutagenic" tse lekaneng ho qhaqha oli, mafura le rabara, tse molemo haholo bakeng sa ho monya oli, empa li le mpe haholo bakeng sa tikoloho eohle, tšilafalo ea nako e telele e ka ba ea feta ea oli.

Lilemong tse latelang, liketsahalo tse sa tsitsang li ile tsa etsahala, ha batšoasi ba litlhapi metsing a lebōpong la leoatle la Gulf of Mexico ba ile ba tšoara liphoofolo tse ngata tse fetotsoeng, ho akarelletsa le shrimp e nang le lihlahala tsa oli lihloohong tsa bona, litlhapi le shrimp ntle le mahlo, litlhapi tse nang le liso tsa exudate, makhala le masoba likhetleng tsa tsona, makhala le shrimp tse se nang manala, le palo e kholo ea liphoofolo tse likhetla tse thata tseo likhetla tsa tsona tse thata li ileng tsa fetoha likhetla tse bonolo. Kou ea Mexico e fana ka karolo ea 40 lekholong ea lijo tsa leoatleng United States, 'me nakong ena, karolo ea 50 lekholong ea li-shrimp tse ileng tsa tšoaroa li fumanoe li se na mahlo. Phuputso e 'ngoe e entsoeng ke Univesithi ea South Florida e fumane hore tšenyo ea letlalo le liso tsa litlhapi pele ho tšilafalo e ne e le e le' ngoe feela ho tse sekete, athe ka mor'a tšilafalo e ile ea eketseha ka makhetlo a 50 ho ea ho 5%.

Leha ho le joalo, ka mor’a ketsahalo eo ea tšilafalo, tlaleho ea sechaba ea FDA e ile ea bolela hore lijo tsa leoatleng Koung ea Mexico li sireletsehile joaloka pele ho kotsi, ’me batho ba ka li ja ka khotso ea kelello. Lijo tsa leoatleng tsa Gulf of Mexico li bile litekong tse thata ka ho fetisisa lefatšeng. Matsatsi a 'maloa hamorao, Khamphani ea Oli ea BP e ile ea lefa $7.8 bilione ho baahi le batšoasi ba litlhapi ba Koung e amehileng. Ha ho bothata, ke hobane'ng ha u lefella chelete e ngata hakaale?

III Phapang ea liphoofolo tsa metsing

Maemo a tšoanang a ntse a tsoela pele ho etsahala lefatšeng lohle. Ka 2014, ho ile ha fumanoa setopo sa dolphin sa likhoeli tse 12 lebōpong la leoatle Türkiye. Dolphin ena e na le lihlooho tse peli 'me mahlo a eona ha a e-s'o hōle ka ho feletseng. Ka 2011, batšoasi ba litlhapi ba Lihlekehlekeng tsa Florida ba ile ba hapa lishaka tse nang le lihlooho tse peli, tse tšoanang le lishaka tse tharo tse hlahang lifiliming tsa saense. Ka mor'a moo, litsebi tsa baeloji ea metsing Univesithing ea Michigan li ile tsa qhaqha shaka 'me tsa paka hore ke shaka ea sebele. Ka lebaka la hore lishaka tse peli tse nang le lihlooho tse peli le li-dolphin tse nang le lihlooho tse peli li arolelana 'mele o tloaelehileng ka lihlooho tse peli tse tloaelehileng, bo-rasaense ba hanne monyetla oa hore phetoho ena e simolohile ho mafahla a kopaneng.

Ka Pulungoana 2016, sekepe se nkileng lithane tse 5000 tsa li-protein tsa boenjiniere tsa whey (bakeng sa merero ea boikoetliso) se ile sa kopana le meea e matla Atlantic mme sa lahleheloa ke boholo ba thepa ea sona. Likhoeli tse seng kae hamorao, batšoasi ba litlhapi ba Maeurope ba ile ba tšoasa litlhapi tse fetotsoeng lebōpong le ka bophirimela la Fora, tse nang le mesifa e matla, haholo-holo mesifa ea mohlahare e matla ka tsela e ikhethang. Batšoasi ba bang ba litlhapi le bona ba fumane hore manala a maholo a makhala a sebakeng seo le ’ona a matla ’me a matla ho feta pele. Bo-rasaense ba fana ka maikutlo a hore e ka 'na ea bakoa ke tahlehelo ea phofo ea protheine,' me ka nako e telele, e ka lebisa ho mefuta e fapaneng ea bophelo ba leoatleng la North Atlantic le nts'etsopele ea maoto le matsoho a tšoanang le a batho, hammoho le 'mele e meholo le e matla haholoanyane.

Leha liketsahalo tsena li hohetse tlhokomelo ho tsoa mecheng ea litaba tsa sechaba, 'muelli oa Mokhatlo oa Marine o netefalitse sechaba hore ha ho na letho le ka tšoenyehang ka lona, ​​​​'Muelli o itse, "Mecha ea litaba ea tikoloho e fetelletse ka bolotsana litlaleho tse mabapi le libopuoa tse matla haholo le tse tsoetseng pele tsa leoatleng. Letsatsi le leng le le leng, thepa e lahleheloa ke leoatle, empa likokoana-hloko tse haufi tsa metsing ha li amehe. karolo ea bobeli ho tse tharo ea lefatše ke leoatle, ’me haeba ho na le ntho e silafatsang karolo e itseng, ho na le libaka tse ngata tseo liphoofolo tse hlaha li ka fallang ho tsona. Ho feta moo, le haeba litlhapi tse itseng li ka beha batho kotsing, ke hobane’ng ha li etsa joalo? Ha ho letho leo re le entseng hore ba se ke ba thaba.

Na ha hoa lekana hore batho ba silafatse tikoloho molemong oa bona ka bobona ho etsa hore lintho tse ling tse phelang li ikutloe li nyonyeha? Haeba ho ne ho e-na le Godzilla lefatšeng lee, na ho ne ho ntse ho tla ba le lebaka la ho ntša batho kotsi? Ha ke tsebe hore na ehlile batho ba litsi tsena ke maoatla kapa ba thijoa ke chelete. Ke lumela hore bohle ba matsoalo le lerato ba tla hanyetsa tšilafalo ea Japane ea tikoloho le ho qhalloa ha eona ha metsi a litšila a nyutlelie Pacific. Joalo ka ha metsoalle e meng e boletse, haeba metsi a litšila a nyutlelie a bolokehile e le kannete, ha re hloke hore baetapele ba Majapane le Korea Boroa ba a noe (mohlomong ha ba na sebete). Ha feela e ntse e sebelisoa ho nosetsa masimo a meroho Japane le Korea Boroa, ke ts'ebeliso ea 'nete ea metsi a litšila.
