Kwete vese kubviswa kwemafuta Izvo zvakafanana sezvo mune dzimwe nzvimbo zviri nyore uye zvishoma zvishoma zvinokuvadza kunharaunda kupfuura kune dzimwe nzvimbo.
Kuputika kwe tar jecha mafuta Icho chakanyanya kuomarara uye chinokonzeresa kukuvara kukuru kwezvakatipoteredza. Sezvo zvinoda kuvhura mugodhi mugodhi, shandisa yakawanda zviwanikwa zviwanikwa senge simba uye mvura mukuwedzera kumakemikari ane njodzi.
KuAlberta, Canada inotarisirwa kutanga kutora mafuta kubva kumasandi ejira, zvichikonzera kushorwa kwakanyanya kubva kune vanoona nezvezvakatipoteredza uye mamwe mapoka enharaunda munyika.
Maitiro ekubvisa erudzi urwu rwe petroleum iri kusvibisa zvakanyanya kupfuura iya yakatorwa mumatsime emunyika dzeArabhu kana Venezuela. Iyo isina kuchena kubva mujecha re bhitumini kana bhitumini Huwandu hwemvura nemakemikari anofanirwa kushambidzwa kupatsanura bhitumini kubva mujecha nevhu.
Bhitumini iyi inogadziriswa kuti ishanduke kuita mafuta asi inoda simba rakawanda kudarika bhitumini yakajairika.
Dambudziko muCanada kuwedzera kune iyo kusvibiswa Chichaburitsa ndechekuti idzi sandi tara dzinowanikwa pasi pezviuru zvemakiromita emasango, saka vanozotemerwa masango ekuchera oiri.
Zvakare kana ichinge yashandurwa kuita mafuta Oiri isina kuchena iyi yakaratidza kuti inogadzira emissions akawanda painopiswa, zvichidaro kuwedzera kusvibiswa kwezvakatipoteredza.

Hurumende dzeChina neCanada ndidzo dzakazivisa kushandiswa kwerudzi urwu rwemhando isina kuchena mumakore anotevera.
Kubviswa kwemafuta mukati mawo ibasa rinogadzira zvakashata ezvemamiriro ekunze asi zvakatonyanya kana richiitwa mune bhitumini jecha.
Izvi zvinoratidza kuti makambani emafuta nehurumende vanofarira bhizinesi pane kutarisira iyo nzvimbo uye hutano hwevanhu nekupa mvumo rudzi urwu rwekushandisa zvisirizvo.
