Tinogara papuraneti yakanaka, asi zvinosuwisa kuti zviri kuwedzera kuoma kuwana nzvimbo dzakachena. Nhasi, plastiki ndechimwe chezvinhu zvinoshandiswa zvakanyanya, uye zvakare ndeimwe yeinotora iyo yakareba kuti iore; muchokwadi, bhegi repurasitiki riri nyore rinogona kutora makore zana nemakumi mashanu kuti ridzikise. Uye zvakadaro ... zvinoita sekunge izvozvi hapana chinozochinja.
Uye inofanira: isu takagadzira anopfuura mabhiriyoni masere matani ematani epurasitiki kubvira 8 maererano neongororo yakatungamirwa kubva kuUC Santa Barbara neyemaindasitiri ecologist Roland Geyer. Tiri kuenda kupurasitiki here?
Kunyatsoona zvinoonekwa, zvinopfuura zvingangoita. Geyer nechikwata chake vakaona kuti kugadzirwa kwepasi rese kwepurasitiki neshinda zvakawedzera kubva pamamiriyoni maviri ematani matani muna 2 kusvika pamamiriyoni mazana mana emamiriyoni muna 1950. Uye kumhanya kwekugadzirwa kwepurasitiki hakuite kunge kuri kudzikira. Pamazere resini uye epurasitiki tambo dzakaburitswa pakati pa1950 na2015, inenge hafu yakaburitswa mumakore gumi nematatu apfuura.
Chinhu chakaipisisa hachisi chigadzirwa chaicho, icho chave kutonetseka, asi chokwadi chekuti zvinotora anopfuura makore zana kudzikisira, kana kutopfuura. Panyaya iyi, mumwe munyori wedzidzo Jenna Jambeck, purofesa weinjiniya paUniversity yeGeorgia, akati "mapurasitiki mazhinji haagadzirise nzira ipi neipi, marara epurasitiki anogadzirwa nevanhu aigona kuve nesu kwemazana kana kunyange zviuru zvemakore".
Ko iyo plastic yese inoenda kupi? Chikamu chakakosha, zvinosuwisa, chinoenda kune zvakasikwa nharaunda. Muna 2015 chete, 79% yekugadzirwa yakaguma mumakungwa nenzvimbo dzepanyama. Kuti isu tiwane pfungwa yekukura kwedambudziko, tinofanirwa kuzviziva pamamiriyoni mazana maviri nemakumi maviri nemashanu ematani ematani akagadzirwa muna275, angangoita mamirioni masere akapinda mugungwa.
Kunyangwe zvisiri zvekubvisa mapurasitiki kubva muhupenyu hwedu, vaongorori vanodavira kuti zvinokurumidza kutora matanho ekudzivirira kupedzisira wagara mupurasitiki.
