Ukuqongelelwa kwepulasitiki olwandle namabhishi sekuba yinkinga yomhlaba wonke. Izigidigidi zamakhilogremu zepulasitiki zitholakala kumaphesenti angama-40 okuguqulwa okuxegayo ebusweni bezilwandle zomhlaba. Esilinganisweni samanje, ipulasitiki kulindeleke ukuthi kudlule zonke izinhlanzi olwandle ngo-2050.
Ukuba khona kwepulasitiki endaweni yasolwandle kubangela impilo yasolwandle futhi uthole ukunakwa okuningi emphakathini wesayensi kanye nomphakathi eminyakeni yamuva. Kwangeniswa ipulasitiki emakethe ngawo-1950s, futhi kusukela ngaleso sikhathi, ukukhiqizwa kwepulasitiki emhlabeni kanye nodoti wepulasitiki wasolwandle kukhuphuke kakhulu. Inani elikhulu lepulasitiki likhishwa ezweni liye kwisizinda sasolwandle, futhi umthelela wepulasitiki endaweni yasolwandle uyangabazeka. Inkinga iya ngokuya iba yimbi ngoba isidingo sepulasitiki futhi, esihlobene, ukukhululwa kwemfuculi yepulasitiki olwandle kungakhula. Kukhiqizwe amathani ayizigidi ezingama-359 (MT) ngonyaka we-2018, amathani alinganiselwa ezigidini eziyi-145 agcina ezalwane olwandle. Ikakhulu, izinhlayiya ezincane zeplastiki zingangezwa nge-biota yasolwandle, kubangele imiphumela elimazayo.
Ucwaningo lwamanje alukwazanga ukuthola ukuthi imfucuza yepulasitiki ihlala kanjani olwandle. Ukuqina kwamapulasitiki kudinga ukucekelwa phansi kancane, futhi kukholelwa ukuthi amapulasitiki angaphikelela emvelweni isikhathi eside. Ngaphezu kwalokho, imiphumela yobuthi namakhemikhali ahlobene akhiqizwa ukonakala kwepulasitiki endaweni yasolwandle futhi kudingeka afundwe.
Ubuchwepheshe beFrankstar ubandakanyeka ekunikezeni imishini yasolwandle kanye nezinsizakalo zezobuchwepheshe ezifanele. Sigxile ekubukeni kwasolwandle kanye nokuqapha kolwandle. Ukulindela kwethu ukuhlinzeka ngedatha enembile neqinile yokuqonda okungcono kolwandle lwethu oluhle. Sizokwenza konke okusemandleni ukusiza ama-Marine En Empiologists aphenye futhi axazulule izinkinga zemvelo zokungcola kwepulasitiki olwandle.
