Nyanja ya Pacific ndiye nyanja yayikulu kwambiri padziko lapansi. Dera lake lili pafupifupi ma 180 kilomita lalikulu, omwe amaphatikizanso nyanja zambiri. Chifukwa cha mphamvu yayikulu ya anthropogenic, matani mamiliyoni amadzi amaipitsidwa ndi zinyalala zapakhomo ndi mankhwala.
Kuwononga zinyalala
Ngakhale ndi dera lalikulu, Nyanja ya Pacific imagwiritsidwa ntchito mwakhama ndi anthu. Kupha nsomba, kutumiza, migodi, zosangalatsa komanso kuyesa zida za nyukiliya kumachitika kuno. Zonsezi, mwachizolowezi, zimaphatikizidwa ndi kutulutsa zinthu zosiyanasiyana ndi zinthu.
Paokha, kuyenda kwa chotengera pamadzi kumabweretsa mawonekedwe a utsi kuchokera ku injini za dizilo pamwamba pake. Kuphatikiza apo, makina ovuta, monga zombo, samachita popanda kutulutsa madzi. Ndipo ngati mafuta a injini sangayembekezere kutuluka pa sitima yapamadzi, ndiye kuti kuchokera kuzombo mazana zikwi zakale ndizosavuta.
Masiku ano, munthu wosowa amaganiza za vuto lotaya zinyalala pazenera. Kuphatikiza apo, izi sizodziwika ku Russia kokha komanso kwa nzika zakumayiko ena. Zotsatira zake, zinyalala zimaponyedwa kuchokera pamakomo a sitima zapamadzi, oyendetsa sitima, oyendetsa sitima ndi zombo zina. Mabotolo apulasitiki, matumba, zotsalira zonyamula sizimasungunuka m'madzi, sizowola kapena kumira. Amangoyandama pamwamba ndikuyandama limodzi mothandizidwa ndi mafunde.
Zinyalala zazikulu kwambiri m'nyanja zimatchedwa Great Pacific Garbage Patch. Ichi ndi "chilumba" chachikulu chamitundu yonse ya zinyalala zolimba, zokuta dera lokwana pafupifupi kilomita imodzi miliyoni. Idapangidwa chifukwa cha mafunde omwe amabweretsa zinyalala kuchokera kumadera osiyanasiyana am'nyanja kupita kumalo amodzi. Dera la zinyalala zakunyanja zikukula chaka chilichonse.
Ngozi zamakono monga gwero la kuipitsa
Zombo zankhondo zamafuta ndizomwe zimayambitsa kuipitsa mankhwala m'nyanja ya Pacific. Ichi ndi mtundu wa chotengera chomwe chimapangidwira kunyamula mafuta ochuluka. Nthawi iliyonse yadzidzidzi yokhudzana ndi kukhumudwa kwa akasinja onyamula katundu, mafuta amalowa m'madzi.
Kuwononga kwakukulu kwambiri panyanja ya Pacific ndi mafuta kunachitika mu 2010. Kuphulika ndi moto papulatifomu yamafuta yomwe ikugwira ntchito ku Gulf of Mexico zawononga mapaipi am'madzi. Zonse pamodzi, matani opitilira 7 biliyoni amafuta adaponyedwa m'madzi. Malo owonongeka anali ma kilomita lalikulu 75,000.
Kupha nyama
Kuphatikiza pa kuwonongeka kwakanthawi, umunthu umasinthiratu zomera ndi nyama za Pacific Ocean. Chifukwa cha nyama zosaganizira, mitundu ina ya nyama ndi zomera zawonongedweratu. Mwachitsanzo, kumbuyoku m'zaka za zana la 18, "ng'ombe yam'nyanja" yotsiriza - nyama yofanana ndi chidindo ndikukhala m'madzi a Nyanja ya Bering, idaphedwa. Zomwezi zatsala pang'ono kugwera mitundu ina ya anangumi ndi zisindikizo zaubweya. Panopa pali malamulo okhwima okhudza kutulutsa nyamazi.
Kusodza kosaloledwa kumayambitsanso nyanja ya Pacific. Chiwerengero cha zamoyo zam'madzi pano ndizochulukirapo, koma matekinoloje amakono amatheketsa kuti tipeze magawo akulu mdera lina kwakanthawi kochepa. Pamene kusodza kumachitika nthawi yodzala, kudzipulumutsa kwa anthu kumatha kukhala kwamavuto.
Mwambiri, Pacific Ocean ikukumana ndi mavuto a anthropogenic omwe amakhala ndi zovuta zoyipa. Apa, monga pamtunda, pali kuipitsa ndi zinyalala ndi mankhwala, komanso kuwononga kwakukulu kwa nyama.
