I-Pacific Ocean yindawo enkulu yamanzi emhlabeni. Indawo yayo ingamakhilomitha-skwele ayizigidi eziyi-180, okubandakanya nolwandle oluningi. Ngenxa yethonya elinamandla le-anthropogenic, izigidi zamathani wamanzi zingcoliswe ngendlela ethile ngemfucuza yasekhaya kanye namakhemikhali.
Ukungcoliswa kukadoti
Ngaphandle kwendawo yayo enkulu, iPacific Ocean isetshenziswa ngabantu. Ukudoba ezimbonini, ukuthunyelwa kwemikhumbi, ezokumbiwa phansi, ezokungcebeleka ngisho nokuhlolwa kwezikhali zenuzi kuyenziwa lapha. Konke lokhu, njengenjwayelo, kuhambisana nokukhululwa kwezinto ezahlukahlukene nezinto.
Ngokwako, ukuhamba komkhumbi ebusweni bamanzi kuholela ekubonakaleni kokukhishwa kwezinjini zikadizili ngaphezulu kwawo. Ngaphezu kwalokho, izindlela eziyinkimbinkimbi, njengemikhumbi, akuvamile ukuthi zenze ngaphandle kokuvuza koketshezi olusebenzayo. Futhi uma uwoyela wenjini kungenakwenzeka ukuthi uphume ku-liner cruise, khona-ke kusuka emakhulwini ezinkulungwane zemikhumbi yokudoba endala kulula.
Kulezi zinsuku, umuntu ongandile ucabanga ngenkinga yokulahla udoti ngefasitela. Ngaphezu kwalokho, lokhu kuvamile hhayi eRussia kuphela, kodwa nakwabahlali bakwamanye amazwe. Ngenxa yalokhu, udoti ulahlwa kusuka emikhunjini yemikhumbi yezimoto, abahamba ngezinyawo, abasebenza ngolwandle neminye imikhumbi. Amabhodlela epulasitiki, izikhwama, izinsalela zokupakisha azincibiliki emanzini, aziboli noma zicwile. Zivele zintante ngaphezulu bese zintanta ndawonye ngaphansi kwethonya lemisinga.
Ukuqoqwa kwenqwaba enkulu kunazo zonke olwandle kubizwa ngokuthi yiGreat Pacific Garbage Patch. Lesi "siqhingi" esikhulu sazo zonke izinhlobo zemfucumfucu eqinile, emboza indawo engamakhilomitha-skwele ayisigidi. Lakhiwa ngenxa yemisinga eletha udoti ovela ezingxenyeni ezihlukene zolwandle endaweni eyodwa. Indawo yokulahla udoti olwandle lukhula minyaka yonke.
Izingozi zobuchwepheshe njengomthombo wokungcola
Ukuphahlazeka kwamathangi kawoyela kungumthombo ojwayelekile wokungcola kwamakhemikhali oLwandlekazi iPacific. Lolu wuhlobo lomkhumbi olwenzelwe ukuthwala uwoyela omningi. Kunoma yiziphi izimo eziphuthumayo ezihlobene nokucindezelwa kwamathangi empahla yomkhumbi, imikhiqizo kawoyela ingena emanzini.
Ukungcoliswa okukhulu kwePacific Ocean ngamafutha kwenzeka ngo-2010. Ukuqhuma nomlilo emsamo kawoyela osebenza eGulf of Mexico kulimaze amapayipi angaphansi kwamanzi. Sekukonke, amathani kawoyela angaphezu kwezigidi eziyizinkulungwane eziyisikhombisa aphonswa emanzini. Indawo engcolisiwe yayingamakhilomitha-skwele angama-75,000.
Ukuzingela ngokungemthetho
Ngaphezu kokungcola okuhlukahlukene, isintu siguqula ngqo izitshalo nezilwane zoLwandlekazi iPacific. Ngenxa yokudla okungacatshangwa, ezinye izinhlobo zezilwane nezitshalo ziqothulwe ngokuphelele. Isibonelo, emuva ngekhulu le-18, "inkomo yasolwandle" yokugcina - isilwane esifana nophawu futhi esihlala emanzini oLwandle iBering, sabulawa. Isiphetho esifanayo sicishe sehlela ezinye izinhlobo zemikhomo nezimpawu zezinwele. Manje kunezinhlaka eziqinile zokulawula ukukhishwa kwalezi zilwane.
Ukudoba ngokungemthetho nakho kudala umonakalo omkhulu oLwandlekazi iPacific. Inani lempilo yasolwandle lapha likhulu kakhulu, kepha ubuchwepheshe besimanje benza kube lula ukubamba imiqulu emikhulu endaweni ethile ngesikhathi esifushane. Lapho ukudoba kwenziwa ngesikhathi sokuzala, ukuzibuyisa kwabantu kungaba yinkinga.
Ngokuvamile, iPacific Ocean ibhekene nengcindezi ye-anthropogenic enemithelela emibi yakudala. Lapha, njengasemhlabeni, kukhona ukungcoliswa kukadoti namakhemikhali, kanye nokubhujiswa okukhulu komhlaba wezilwane.
