Izvo zvinodiwa zvekuchengetedzwa kwezvakatipoteredza zvekurongedza zvinovandudzwa, uye kushandiswa kwepepa kurongedza muminda yakawanda mune ramangwana kunowedzera uye kwakawedzera.
1, Indasitiri yemapepa inogadzirwazve.
Indasitiri yekurongedza mapepa yave ichionekwa seindasitiri yakagadzikana chikonzero chekuti bepa rinoshandiswazve.
Mazuva ano, kurongedza kunogona kuoneka kwese kwese muhupenyu hwedu. Mhando dzese dzezvigadzirwa zvine mavara uye akasiyana muchimiro. Chinhu chekutanga chinobata maziso evatengi ndiko kurongedza kwezvigadzirwa. Mukuvandudza kweiyo indasitiri yekurongedza, mapepa ekurongedza, seyakajairwa kurongedza zvinhu, anoshandiswa zvakanyanya mukugadzira uye hupenyu hwezuva nezuva. Nepo iyo "plastic restriction" ichigara ichidikanwa, kurongedza mapepa kunogona kunzi ndiyo yakanyanya kunaka zvinhu.
2.Sei tichida kushandisa pepa kurongedza?
Mushumo wakaitwa neWorld Bank wakaratidza kuti China ndiyo inokonzera marara akawanda pasi rose. Muna 2010, maererano nehuwandu hweChina Urban Environmental Sanitation Association, China inogadzira matani angangoita bhiriyoni imwe yemarara gore rega rega, kusanganisira matani 400 miriyoni emarara emumba uye mazana mashanu emamiriyoni matani emarara ekuvaka.
Iye zvino dzinenge dzese mhuka dzemugungwa dzine zvinosvibisa zvepurasitiki mumiviri yavo. Kunyangwe muMariana Trench, makemikari epurasitiki ezvigadzirwa zvePCBs (polychlorinated biphenyls) akawanikwa.
Kushandiswa zvakanyanya kwePCB mumaindasitiri kwakakonzera dambudziko repasi rose rezvakatipoteredza.Polychlorinated biphenyls (PCBs) icarcinogens, iyo iri nyore kuunganidza muadipose tissue, zvichikonzera huropi, ganda uye zvirwere zvevisceral, uye kukanganisa tsinga, kubereka uye immune system. MaPCB anogona kukonzera zvirwere zvakawanda zvevanhu, uye anogona kutapurirana kumwana ari mudumbu kuburikidza ne placenta yaamai kana kuyamwisa. Pashure pemakumi emakore, ruzhinji rwevakabatwa vachine chepfu isingagoni kubudiswa.
Aya marara epurasitiki anoyerera achidzokera kune cheni yako yechikafu nenzira isingaonekwe. Aya mapurasitiki anowanzo ane carcinogens nemamwe makemikari, ayo ari nyore kuva nemigumisiro inoparadza pahutano hwevanhu. Mukuwedzera pakushandurwa kuita makemikari, mapurasitiki achapinda mumuviri wako mune imwe fomu uye anoramba achiisa utano hwako pangozi.
Pepa kurongedza ndeye "girinhi" kurongedza. Iyo ndeyezvakatipoteredza uye inogona kushandiswa zvakare. Nekutarisisa kwekuchengetedzwa kwezvakatipoteredza, makadhibhokisi mabhokisi anozonyanya kufarirwa nevatengi.
