Ka 2050, ho tla ba le lithane tse ka bang limilione tse likete tse 12 tsa litšila tsa polasetiki lefatšeng

Batho ba hlahisitse lithane tse limilione tse likete tse 8,3 tsa polasetiki.Ka 2050, ho tla ba le lithane tse ka bang limilione tse likete tse 12 tsa litšila tsa polasetiki lefatšeng.

Ho ea ka phuputso e entsoeng ho Journal Progress in Science, ho tloha mathoasong a lilemo tsa bo-1950, lithane tse limilione tse likete tse 8.3 tsa polasetiki li 'nile tsa hlahisoa ke batho, tseo boholo ba tsona li fetohileng litšila, tse ke keng tsa hlokomolohuoa hobane li behiloe ka har'a litšila kapa li hasane ka tlhaho. tikoloho.

Sehlopha, se etelletsoeng ke bafuputsi ba Univesithi ea Georgia, Univesithi ea California, Santa Barbara le Marine Education Association, ba ile ba qala ho hlahloba tlhahiso, tšebeliso le qetello ea lihlahisoa tsohle tsa polasetiki lefatšeng ka bophara.Bafuputsi ba ile ba bokella lintlha tsa lipalo-palo mabapi le tlhahiso ea li-resin tse fapaneng tsa indasteri, likhoele le li-additives, 'me ba kopanya lintlha ho latela mofuta le tšebeliso ea lihlahisoa.

Limilione tsa lithane tsa polasetiki li kena maoatleng selemo se seng le se seng, li silafatsa maoatle, li qhala mabōpo le ho beha liphoofolo tse hlaha kotsing.Likaroloana tsa polasetiki li fumanoe mobung, sepakapakeng esita le libakeng tse hole haholo tsa Lefatše, joalo ka Antarctica.Li-microplastics li boetse li jeoa ke litlhapi le libōpuoa tse ling tsa leoatle, moo li kenang ketane ea lijo.

Lintlha li bonts'a hore tlhahiso ea polasetiki ea lefats'e e ne e le lithane tse limilione tse 2 ka 1950 mme e eketsehile ho lithane tse limilione tse 400 ka 2015, e fetang thepa leha e le efe e entsoeng ke motho ntle le samente le tšepe.

Ke 9% feela ea lihlahisoa tsa polasetiki tse litšila tse sebelisoang hape, tse ling tse 12% lia chesoa, 'me tse setseng tse 79% li patiloe botebong ba lithōle kapa li bokelletsoeng tikolohong ea tlhaho.Lebelo la tlhahiso ea polasetiki ha le bontše matšoao a ho fokotseha.Ho latela mekhoa ea hajoale, ho tla ba le lithane tse ka bang limilione tse likete tse 12 tsa litšila tsa polasetiki lefatšeng ka 2050.

Sehlopha se fumane hore ha ho na tharollo ea bullet ea silevera ea ho fokotsa tšilafalo ea polasetiki ea lefats'e.Ho e-na le hoo, ho hlokahala phetoho ho pholletsa le ketane eohle ea phepelo, ba re, ho tloha ho etsoa ha polasetiki, ho sebelisoa pele ho sebelisoa (e tsejoang e le holimo) le ka mor'a ho sebelisoa (ho tsosolosa). and reusing) ho emisa ho ata ha tšilafalo ea polasetiki tikolohong.
