Ukunqwabelana kwepulasitiki olwandle nasemabhishi sekuyinkinga yomhlaba wonke. Izigidigidi zamaphawundi epulasitiki zingatholakala cishe kumaphesenti angama-40 wokuhlangana okuzungezayo ebusweni bezilwandle zomhlaba. Ngokwesilinganiso samanje, ipulasitiki kulindeleke ukuthi ibe ngaphezu kwazo zonke izinhlanzi ezisolwandle ngo-2050.
Ukuba khona kwepulasitiki endaweni yaseMarine kubangela usongo empilweni yasolwandle futhi sekuthole ukunakwa okukhulu emphakathini wesayensi kanye nomphakathi eminyakeni yamuva. Ipulasitiki yethulwa emakethe ngawo-1950s, futhi kusukela lapho, ukukhiqizwa kwepulasitiki yomhlaba wonke kanye nemfucuza yepulasitiki yasolwandle kuye kwanda kakhulu. Inani elikhulu lepulasitiki likhishwa ezweni liye esizindeni sasoLwandle, futhi umthelela wepulasitiki endaweni yasolwandle uyangabazeka. Inkinga iya ngokuba yimbi kakhulu ngoba isidingo sepulasitiki futhi, okuhlobene, ukukhishwa kwemfucumfucu yepulasitiki olwandle kungase kukhule. Kumathani ayizigidi ezingama-359 (Mt) akhiqizwa ngo-2018, alinganiselwa ezigidini ezingama-145 amathani aphelela olwandle. Ikakhulukazi, izinhlayiya zepulasitiki ezincane zingangenwa yi-Marine biota, okubangela imiphumela eyingozi.
Ucwaningo lwamanje alukwazanga ukucacisa ukuthi imfucumfucu yepulasitiki ihlala isikhathi esingakanani olwandle. Ukuqina kwamapulasitiki kudinga ukuwohloka kancane, futhi kukholakala ukuthi amapulasitiki angaqhubeka emvelweni isikhathi eside. Ngaphezu kwalokho, imiphumela yobuthi namakhemikhali ahlobene akhiqizwa ukucekelwa phansi kwepulasitiki endaweni yasolwandle nayo idinga ukucutshungulwa.
I-Frankstar Technology ibambe iqhaza ekuhlinzekeni ngemishini yasolwandle kanye nezinsizakalo zobuchwepheshe ezifanele. Sigxila ekuqapheliseni olwandle kanye nokuqapha olwandle. Esikulindele ukuhlinzeka ngedatha enembile futhi ezinzile ukuze siqonde kangcono ulwandle lwethu oluhle. Sizokwenza konke esingakwenza ukuze sisize izazi zemvelo zasolwandle ukuthi ziphenye futhi zixazulule izinkinga zemvelo zodoti wepulasitiki olwandle.
