Hapana angati magwenga anogona kutyisidzirwa, handiti? Asi chokwadi ndechekuti ivo inzvimbo zvakanyanya kuputsika kupfuura zvatingafungidzira. Zvidyarwa, mhuka uye vanhu vanofungidzirwa mamirioni mazana mashanu vanogara munzvimbo idzi vakajairana nemamiriro ekunze erenje.
Asi kana tembiricha ikaramba ichikwira, upenyu hwavo huchava mungozi huru.
Mukuwirirana nomushumo weUN wemhoteredzo (UNEP), mukati menhambo inobvira muna 1976 kusvikira kuna 2000, avhareji yetembiricha yomugwenga yakakwira. pakati pe0 nembiri madhigirii centigrade, kusiyana nemadhigirii 0 ayo yakakwira mune imwe nyika yose. Migumisiro yegreenhouse iri kukonzera kusanaya kwakanyanya uye kwenguva refu, uye naizvozvo mvura yatove yakaderera iri kuramba ichionekwa.
Magwenga akanyanya kukanganiswa iKalahari muAfrica, uye Atacama muChile. Mune ose ari maviri unogona kuona kuti upenyu hunoedza sei kurarama. Asi havasirivo voga vanobatwa. Kuderera kwemvura kuri kuita kuti nzizi dzipere, seNairi muEgypt, kana Colorado muUnited States. UNEP inoyambira kuti kana greenhouse gasi kubuda, kugoverwa kwemvura kuchakanganiswa zvikuru, kuchiisa utano hwevagari vomugwenga, pamwe chete nohwezvirimwa zvavo nemhuka, mungozi.
Kana tikaramba tichishandisa zvakanyanya mvura yepasi, kugadzira zvivakwa, kana nzvimbo dzekudzidzira zvechiuto, tinogona kushandura mamiriro acho zvachose. Pasinei nezvose, Kaveh Zahedi, mutevedzeri wemukuru weWorld Conservation Center (UNEP), anodaro magwenga anogona kuva zvirimwa zvesimba zvezana rino remakore, pamusoro pekushanda senzvimbo dzinokwezva vashanyi, kana kuwana mishonga mitsva inogona kuvandudza hupenyu hwevanhu.
