Mavharuvhu epurasitikiZvinoshandiswa mumabasa akawanda mukusimudzira maindasitiri munyika yangu, uye zvigadzirwa zvepurasitiki muindasitiri yemakemikari nekuchengetedza zvakatipoteredza zvinokosheswa zvikuru. Zvinotaurwa zvakajeka kuti kukurumidza kwebudiriro kunofanira kukurumidziswa, uye kwakakwezva kutariswa kukuru kubva kumadhipatimendi enyika, zvichida kuti mapurasitiki einjiniya enyika yangu akurumidze kukura. Nokudaro, nyanzvi dzeindasitiri dzinofanotaura kuti indasitiri yepurasitiki yenyika yangu ichatarisana nebudiriro muzvinhu zvese, kunyanya mukuvandudza zvigadzirwa zvepurasitiki zveinjiniya. Kuvandudza kugona kwekuvandudza kwakazvimirira kweindasitiri yekugadzirisa mapurasitiki, kufarirwa kwezvinhu zvitsva, matekinoroji matsva, michina mitsva uye zvigadzirwa zvitsva kwave chinhu chinonyanya kukosheswa.

Mavharuvhu ebhora epurasitiki,mavharuvhu eshavishaviuyemavharuvhu ekuongororazvigadzirwa zvakakosha mumhuri yemavharuvhu, kunyanya nekuti mavharuvhu aya akagadzirwa nemapurasitiki einjiniya, saka zvese maererano nekushanda uye mashandiro, ane zvakanakira. Mwero wekushandiswa kwemavharuvhu epurasitiki munyika yangu Pari zvino, makambani mazhinji atanga kutenga mavharuvhu epurasitiki, uye mamwe makambani emavharuvhu ekunze ari kupinda mumusika mukuru wenyika yangu, achiratidza kufambira mberi kwese kwese munyika.

Mavharuvhu epurasitiki ebhora, mavharuvhu emapuruguru, uye mavharuvhu ekutarisa akakosha zvikuru mune mamwe mapurojekiti ekuchengetedza makemikari nezvakatipoteredza. Nekuda kwekushanda kwakanaka kwemavharuvhu epurasitiki, anogona kusangana nezvinodiwa zvepurojekiti zviri nani kupfuura mamwe mavharuvhu esimbi isina ngura, nekuti mavharuvhu epurasitiki ane huremu hwakaderera, ari nyore kuisa, uye anodhura zvishoma. Anodhura zvishoma uye anogonawo kudzivirira dambudziko rekudonha kwemvura, uye huwandu hwevharuvhu yepurasitiki hudiki, nzvimbo yepasi idikiwo, iri nyore kutakurwa nekuisa, uye kubviswa kwayo nekugadzirisa zviri nyore. Naizvozvo, mukana wekushandisa mavharuvhu epurasitiki muinjiniya. Mikana iri kukura uye kukura uye tariro.

Nhasi uno, nyika yangu yave mugadziri mukuru, mutengi uye mutengesi wezvinhu zvepurasitiki pasi rose. Vamwe vaongorori vakati sezvo tekinoroji yemarasha-ku-olefin ichikura uye ichishandiswa zvakanyanya, zvigadzirwa zvepurasitiki zviri kutsiva simbi zvishoma nezvishoma, girazi, mapaipi emakemikari, mavharuvhu uye mamwe maindasitiri anogamuchirwa, mapurasitiki akavakirwa pazvipenyu uye mamwe mapurasitiki anogona kuora uye zvimwe zvinhu zvitsva zviri kutanga kushandiswa.

Mune ramangwana, kukura kweindasitiri yepurasitiki kuchaenderana nesimba rebhizinesi pacharo kune rumwe rutivi, uye kune rumwe rutivi kuchavimba nesimba remakambani akaunganidzwa. Indasitiri yese yemakemikari ekuchengetedza zvakatipoteredza ichava simba guru rekusimudzira indasitiri yepurasitiki. Vagadziri vanofanirwa kuvandudza simba ravo rehunyanzvi uye kuramba vachivandudza mhando yezvigadzirwa zvavo uku vachideredza mitengo, kuitira kuti mhando yavo yevharuvhu yepurasitiki igone kutungamira munzvimbo ine mafungu makuru nejecha.
