Mu bihe byashize, umusaruro w'icyayi ku isi (usibye icyayi cy'ibyatsi) wikubye inshuro zirenga ebyiri, ari nacyo cyatumye ubwiyongere bwaimashini yicyayinaumufuka w'icyayiumusaruro. Iterambere ryumusaruro wicyayi cyirabura urenze uwicyayi kibisi. Byinshi muri iri terambere byaturutse mu bihugu bya Aziya, bitewe n’izamuka ry’ibicuruzwa mu bihugu bitanga umusaruro. Nubwo iyi ari inkuru nziza, Ian Gibbs, umuyobozi w’inama mpuzamahanga y’icyayi, yemeza ko nubwo umusaruro wiyongereye, ibyoherezwa mu mahanga byakomeje kuba byiza.

Icyakora, abanditsi bavuga ko ikibazo gikomeye kigira uruhare mu kugabanuka kw’icyayi cyirabura, kandi kikaba kitaganiriweho mu nama iyo ari yo yose y’icyayi yo muri Amerika y'Amajyaruguru y’icyayi, ari ubwiyongere mu kugurisha icyayi cy’ibyatsi. Abaguzi bakiri bato bashima imiterere icyayi cyimbuto, icyayi gifite impumuro nziza nicyayi kiryoshye bizana icyayi cyiza. Mu cyorezo cya Covid-19, kugurisha icyayi, cyane cyane “byongera ubudahangarwa,” “kugabanya imihangayiko,” no “gufasha kuruhuka no gutuza,” mu gihe abaguzi bashakisha cyane kandi bakagura ibicuruzwa by’icyayi bikora kandi biteza imbere ubuzima. Ikibazo nuko ibyinshi muri ibyo Mu gihe rero ibigo by’ubushakashatsi ku isoko ku isi bigabanya ubwiyongere bw’ikoreshwa ry’icyayi ku isi (icyayi nicyo kinyobwa cya kabiri gikoreshwa cyane ku isi nyuma y’amazi), ubwiyongere bugaragara nkicyayi cy’ibimera, atari byiza kubyara icyayi cyirabura cyangwa icyatsi.

Mubyongeyeho, McDowall yasobanuye ko urwego rwa mashini yaicyayi gikonjesha hamwe na trimmeririyongera cyane, ariko imashini ikoreshwa cyane cyane mu gutanga icyayi cyiza, kandi imashini itera ubushomeri bwabakozi batora icyayi. Abakora ibicuruzwa binini birashoboka ko bazakomeza kwagura imashini, mugihe abayikora bato badashobora kwishyura ikiguzi kinini cyimashini, abayikora baranyeganyezwa, bizatuma bareka icyayi bahitamo ibihingwa byunguka cyane nka avoka, eucalyptus, nibindi.
