Hangata polasetiki e lahloa ka tsela e sa lokelang, ebang ke ka matlakala a lapeng, matlakala a indasteri, kapa mesebetsi ea boikhathollo. Polasetiki e sa laoloeng hantle e tsoang libakeng tsa litoropo le lebopong la leoatle e ka fella leoatleng ka lebaka la metsi a noka kapa metsi a sefefo.
2. Ho Aroha ha Microplastic:
Polasetiki tikolohong ea leoatle e ka arohana likotoana tse nyenyane tse bitsoang li-microplastic ka lebaka la ho pepesehela khanya ea letsatsi (photodegradation), maqhubu a leoatle, le likamano le lintho tse phelang metsing. Li-microplastic tsena li ka meloa ke liphoofolo tsa leoatleng ebe li kena ketaneng ea lijo, li silafatsa eseng feela bophelo ba leoatle empa le batho ba li jang.
3. Kotsi Bophelong ba Leoatleng:
Liphoofolo tsa metsing tse kang linonyana, litlhapi le liphoofolo tse anyesang hangata li nahana hore polasetiki ke lijo, e leng se ka lebisang likotsing tsa ka hare, tlala le lefu. Ho feta moo, polasetiki e tšoasehileng linthong tse phelang metsing e ka sitisa motsamao le ho baka kotsi kapa lefu.

3. Tšebelisano-'moho le Indasteri:
Surabaya e sebelisana le liindasteri tse fapaneng ho theha litsi tsa ho sebelisa lintho hape le taolo ea litšila. Indasteri ena e boetse e bapala karolo ea ho fana ka theknoloji le lichelete tse hlokahalang ho tšehetsa boiteko ba ho fokotsa litšila tsa polasetiki.
4. Melawana le Maano:
Mmuso oa toropo o kentse tšebetsong melaoana e tšehetsang, joalo ka thibelo ea mekotla ea polasetiki e sebelisoang hanngoe libakeng tsa mabenkele le limmarakeng tsa setso, 'me o fane ka likhothaletso bakeng sa likhoebo le liindasteri tse kenyang letsoho boitekong ba ho fokotsa litšila tsa polasetiki.
Ka ho utloisisa lipotso tsena tsa mehlala le lipuisano mabapi le polasetiki, re tšepa ho utloisisa hamolemo bothata ba polasetiki le mehato eo re ka e nkang ho laola tšusumetso ea eona e mpe tikolohong. A re sebetseng 'moho ho theha lefatše le hloekileng le le tsitsitseng haholoanyane.
