Amateka y'amasashe ya pulasitiki kuva yavuka kugeza igihe yabujijwe
Mu myaka ya 1970, amasashe yo guhaha ya pulasitiki yari agifite agashya gadasanzwe, none ubu yabaye ibicuruzwa bikwirakwira ku isi hose aho umusaruro wa miliyari imwe buri mwaka ugera kuri buri mwaka. Inzira zayo zigaragara ku isi yose, harimo igice cyo hasi cyane cy’inyanja, umusozi muremure cyane wa Mount Everest n’ibice by’urubura byo mu misozi miremire.

Amasashe ya pulasitiki ateza ibibazo bikomeye ku bidukikije.
Amasashe ya pulasitiki akoreshwa mu gihe cyo kuyakoresha akorwa ate? Abujijwe gute?Ibi byagenze bite?
Mu 1933, uruganda rw’imiti rwo mu mujyi wa Northwich, mu Bwongereza rwakoze ku buryo butaziguye pulasitiki-polyethylene ikoreshwa cyane.

Imifuka ya pulasitiki izwiho kwica utunyamaswa two mu nyanja, twibeshya ko ari jellyfish maze tukayirya.
2002-Bangladesh ni cyo gihugu cya mbere ku isi cyashyize mu bikorwa itegeko ryo guhagarika imifuka mito ya pulasitiki, nyuma yo gusanga bagize uruhare runini mu kuziba imiyoboro y'amazi mu gihe cy'imyuzure ikabije. Ibindi bihugu byatangiye kubyigana. 2011-Isi yose ikoresha imifuka ya pulasitiki miliyoni 1 buri munota.
2017-Kenya yashyize mu bikorwa "guhagarika pulasitiki" gukomeye cyane. Kubera iyo mpamvu, ibihugu birenga 20 ku isi byashyize mu bikorwa "amabwiriza yo guhagarika pulasitiki" cyangwa "amabwiriza yo guhagarika pulasitiki" kugira ngo bigenzure ikoreshwa ry'amasashe ya pulasitiki.
2018 - "Icyemezo cyihuse cy’intambara ya pulasitiki" cyatoranyijwe nk'insanganyamatsiko y'Umunsi Mpuzamahanga w’Ibidukikije, uyu mwaka wateguwe n'Ubuhinde. Ibigo na za guverinoma hirya no hino ku isi byagaragaje ko bishyigikiye, kandi byagaragaje ubushake n'umurava byo gukemura ikibazo cy’imyanda ya pulasitiki ikoreshwa rimwe.
2020- "Kubuza ikoreshwa rya pulasitiki" ku isi hose biri ku murongo w'ibyigwa.
Kunda ubuzima kandi urinde ibidukikije. Kurengera ibidukikije bifitanye isano rya bugufi n'ubuzima bwacu kandi bitugira ishingiro ry'ibindi bintu. Tugomba gutangirira ku tuntu duto dutangira ku ruhande, kandi tukagera ku muco mwiza wo gukoresha bike bishoboka cyangwa kudajugunya imifuka ya pulasitiki nyuma yo kuyikoresha mu kurinda ingo zacu!
