Zamoyo Zosasinthika M'nyanja Pambuyo Poipitsa

Ndi Nyanja ya Pacific Yowonongeka

Kutulutsidwa kwa madzi owonongeka a nyukiliya ku Japan ku Pacific Ocean ndizochitika zosasinthika, ndipo malinga ndi dongosolo la Japan, ziyenera kupitiliza kutulutsidwa kwazaka zambiri. Poyambirira, kuipitsa kotereku kwa chilengedwe kuyenera kutsutsidwa ndi onse okonda moyo ndi chilengedwe. Komabe, chifukwa chokhudzidwa ndi zokonda zambiri, sayansi ndi thanzi zimabedwanso ndi ndalama ndi zokonda.

Malinga ndi momwe mafunde akunyanja ku North Pacific akuwongolera, madzi owonongeka a nyukiliya adzachoka ku Japan ndikuyenda chakum'mawa kumphepete mwa Kuroshio komwe kumayenda chakumpoto m'mphepete mwa nyanja yakum'mawa kwa Japan, komanso mafunde omwe amayenda chakum'mwera kuchokera ku Arctic. Idzawoloka nyanja yonse ya Pacific ndi kukafika pafupi ndi California, USA, ndi kuyenderera chakumpoto kulowera ku Canada pafupi ndi malire a United States ndi Canada, kenako Alaska, Bering Sea, ndi Kamchatka Peninsula ku Russia. Pomaliza, dziko la South Korea (lolowera) lizungulira kubwerera ku Japan; Mbali ina, limodzi ndi mafunde a kum’mwera kwa California omwe amasesa gombe lonse lakumadzulo kwa United States, amakhotera chakumadzulo pafupi ndi equator, kudutsa Hawaii, Papua New Guinea, Indonesia, Palau, ndi Philippines. Kenako, imakhotera kumpoto ndikudutsa ku Taiwan kubwerera ku Japan. Mitsinje ina idzapita ku East China Sea ndi South China Sea pafupi ndi Taiwan, ndipo gawo laling'ono lidzalowa m'madzi pafupi ndi South Korea.

Mukawerenga njirayi, mutha kumvetsetsa chifukwa chomwe Purezidenti waku South Korea amathandizira mopanda manyazi kutulutsa zimbudzi za nyukiliya ku Japan, chifukwa njira yotulutsira ndikulowera kunyanja ya Pacific kummawa, osati Nyanja ya Japan kumadzulo. South Korea idzakhala yomaliza komanso yosadetsedwa kwambiri.

Anthu ena amanena kuti bungwe la International Atomic Energy Agency silikunena kuti ndondomeko ya Japan yochotsa madzi oipa a nyukiliya ikugwirizana ndi mfundo za chitetezo padziko lonse? Komabe, munthawi yeniyeni, International Atomic Energy Agency ilibe miyezo yakuthamangitsidwa kwamadzi onyansa a nyukiliya m'nyanja, koma miyezo yapadziko lonse lapansi yotulutsa madzi onyansa anyukiliya m'nyanja. Pali kusiyana kwakukulu pakati pa ziwirizi. Madzi owonongeka a nyukiliya amangozizira ndi madzi kunja kwa mafuta a nyukiliya a fakitale ya nyukiliya, ndi zida zambiri zodzipatula pakati. Madzi ndi mafuta a nyukiliya sizikukhudzana kapena kuipitsidwa. Madzi onyansa a nyukiliya ku Tokyo ndi mafuta a nyukiliya omwe amakhudzidwa mwachindunji ndi madzi, ndipo m'madzimo muli zinthu zambiri zowononga nyukiliya. Zimenezi n’zofanana ndi kusiyana kwa munthu amene akuyenda pafupi ndi malo opangira magetsi a nyukiliya ndi kuyenda pamalo amene bomba la nyukiliya laphulika.

II Zochitika Zakuwonongeka kwa M'madzi ku United States

Anthu ambiri akudabwa kuti madera oipitsidwa kwambiri pambali pa nyanja zozungulira Japan ndi United States ndi Canada, koma zikuoneka kuti sangamve kutsutsa kwawo. M'malo mwake, msonkhano ku Camp David ku United States kumapeto kwa mwezi uno uvomereza kutulutsa mpweya kwa Japan. Kuipitsidwa kwa nyanja ndi anthu kwakhala kukuchitika kwa nthawi yaitali, ndipo kusagwirizana kwa zofuna, ndalama, ndi mphamvu za mabungwe ena a mayiko ndi mayiko kwakhala chizolowezi. Musaganize kuti Ulaya ndi America ali ndi ufulu weniweni waumunthu ndi kuti chirichonse chimachokera ku zofuna za anthu awo.

Mu Epulo 2010, BP ku UK idaphulika pamalo ake obowola mafuta m'nyanja yakuya ku Gulf of Mexico, zomwe zidapha anthu 11 komanso migolo yamafuta 4.9 miliyoni yomwe idatayikira m'nyanja. Kuphatikiza apo, magaloni 2 miliyoni azinthu zowola mankhwala, monga kuwonongeka kwa petroleum ndi 2-butoxyethanol, adagwiritsidwanso ntchito. Zowonongeka izi zakhala "zosintha" zokwanira kusungunula mafuta, mafuta, ndi mphira, zomwe ndizothandiza kwambiri pakuyamwa mafuta, koma zoyipa kwambiri chilengedwe chonse, Kuipitsa kwanthawi yayitali kumatha kupitilira mafuta.

M'zaka zotsatira, zochitika zosasangalatsa zinachitika, monga asodzi m'mphepete mwa nyanja ya Gulf of Mexico anagwira nyama zambiri mutated, kuphatikizapo shrimp ndi zotupa mafuta pamutu, nsomba ndi shrimp popanda maso, nsomba ndi zilonda exudate, nkhanu ndi mabowo m'zipolopolo zawo, nkhanu ndi shirimpu zopanda zikhadabo, ndi nyama zambiri zolimba zomwe zipolopolo zake zolimba zinasandulika kukhala zipolopolo zofewa. Gulf of Mexico imapereka 40% ya nsomba zam'madzi ku United States, ndipo panthawiyi, 50% ya shrimp yomwe inagwidwa inapezeka kuti alibe maso. Kafukufuku wina wa University of South Florida anapeza kuti kuwonongeka kwa khungu ndi zilonda mu nsomba pamaso kuipitsa anali mmodzi mwa zikwi, pamene pambuyo kuipitsa chinawonjezeka ndi 50 nthawi 5%.

Komabe, zitachitika ngoziyi, lipoti lapoyera la FDA linanena kuti nsomba za m’nyanja za ku Gulf of Mexico tsopano ndi zotetezeka ngati ngoziyo isanachitike, ndipo anthu atha kuzidya ndi mtendere wamumtima. Zakudya zam'madzi za ku Gulf of Mexico zayesedwa mwamphamvu kwambiri padziko lonse lapansi. Patapita masiku angapo, BP Oil Company inalipira $7.8 biliyoni kwa anthu okhala ku Gulf okhudzidwa ndi asodzi. Palibe vuto, bwanji mukulipira ndalama zochuluka chonchi?

III Kusiyana kwa nyama zam'madzi

Zinthu ngati zimenezi zikuchitikabe padziko lonse. Mu 2014, thupi la dolphin la miyezi 12 linapezeka pamphepete mwa nyanja ku Türkiye. Dolphin uyu ali ndi mitu iwiri ndipo maso ake sanakule bwino. Mu 2011, asodzi ku Florida Islands adagwira shaki yamutu iwiri, yofanana ndi shaki yamutu itatu m'mafilimu opeka asayansi. Pambuyo pake, akatswiri a zamoyo za m’madzi a pa yunivesite ya Michigan anagaŵa shaki ndi kutsimikizira kuti inali shaki yeniyeni. Popeza kuti shaki ziwiri zamutu ndi ma dolphin amutu awiri amagawana thupi lofanana ndi mitu iwiri yokhazikika, asayansi amakana kuti kusinthaku kudachokera ku mapasa olumikizana.

Mu November 2016, sitima yonyamula matani 5000 a engineering whey protein supplement (pofuna kuchita masewera olimbitsa thupi) inakumana ndi mphepo yamphamvu ku Atlantic ndipo inataya katundu wake wambiri. Patatha miyezi ingapo, asodzi a ku Ulaya adagwira nsomba zosinthika kumadzulo kwa gombe la kumadzulo kwa France, zomwe zimakhala ndi minofu yolimba, makamaka yamphamvu kwambiri ya nsagwada. Asodzi ena apezanso kuti zikhadabo zazikulu za nkhanu zakumaloko ndi zamphamvu komanso zamphamvu kuposa kale. Asayansi amanena kuti zikhoza kukhala chifukwa cha kutayika kwa mapuloteni a ufa, ndipo m'kupita kwa nthawi, kungayambitse kusiyana kwa moyo wa m'nyanja ya North Atlantic ndi chitukuko cha miyendo yofanana ndi anthu, komanso matupi akuluakulu komanso amphamvu kwambiri.

Ngakhale zochitikazi zakopa chidwi ndi ochezera a pa Intaneti, mneneri wa Marine Association adatsimikizira anthu kuti palibe chodetsa nkhawa, Mneneriyo adati, "Zofalitsa zachilengedwe zidakokomeza moyipa malipoti okhudza zamoyo zam'madzi zamphamvu kwambiri komanso zotukuka. Tsiku lililonse, katundu amatayika panyanja, koma zamoyo zam'madzi zapafupi sizimakhudzidwa. magawo awiri pa atatu a dziko lapansi ndi nyanja, ndipo ngati chinachake chaipitsa gawo linalake, pali malo ambiri kumene nyama zakutchire zimatha kusamuka. Komanso, ngakhale nsomba zina zingawononge anthu, n’chifukwa chiyani zimatero? Palibe chimene tachita kuti asakhale osangalala.

Kodi sikokwanira kuti anthu adetse malo okhala kuti apeze phindu laumwini kupangitsa zamoyo zina kukhala zonyansidwa? Ngati padziko lapansi pakanakhala Godzilla, kodi pakanakhalabe chifukwa chovulaza anthu? Sindikudziwa ngati anthu ochokera m'mabungwewa ndi opusa kapena ngati adatsekeredwa ndi ndalama. Ndikukhulupirira kuti onse amene ali ndi chikumbumtima ndi chikondi adzatsutsa kuipitsidwa kwa chilengedwe ndi dziko la Japan ndi kutaya kwake kwa madzi a nyukiliya ku Pacific. Monga abwenzi ena anena, ngati madzi otayira zida za nyukiliya ali otetezeka, sitifuna kuti atsogoleri aku Japan ndi South Korea amwe (mwina sangayerekeze). Malingana ngati imagwiritsidwa ntchito kuthirira minda yamasamba ku Japan ndi South Korea, ndikugwiritsanso ntchito madzi oipa.
