Mu rwego rwo kubaka ubwubatsi bushimangira,umwenda wa karubonegushimangira birashobora kuvugwa ko byamenyekanye mumyaka yashize, nta babiri, mubyiciro byose kugirango bakore agafuni, basarure abafana benshi, urakoze igice kinini kubyungukiramo bifite ibyiza byihariye, urugero kubaka biroroshye, ni bifite akamaro ko kunoza imikorere yubwubatsi, kugabanya igihe cyubwubatsi, kandi ingaruka zayo zo gushimangira ziragaragara, Irashobora kunoza neza ubushobozi bwo gutwara no gutuza kwibigize.

Ariko, mugukoresha nyabyo inzira, harigihe hariho abakiriya na ba nyirubwite kubaza ubuzima bwa serivisi yimyenda ya fibre fibre kugeza ryari?Nigute ushobora kwemeza neza gukoresha amabwiriza ya karuboni fibre?Inshuti nyinshi zifite gushidikanya, none uyumunsi kandi tuzasesengura ikibazo muriki kibazo.

Igisubizo cyoroshye ni imyenda ya karubone, ishobora kumara imyaka 50 niba yujuje ibyangombwa kandi nta makosa akomeye yo kubungabunga.
