Kwimibhobho yefeni ethe tyaba esiyenzayo, imibala eyahlukileyo imele amazinga ahlukeneyo okuhamba. Umzekelo, iiplastiki zethu zeplastiki ezisetyenziselwa ukusetyenziswa kwezolimo zisetyenziswa kakhulu kwiindawo zokutshiza ngokuzenzekelayo, ezifana nokukhuselwa kwezityalo zokutshiza i-pesticides.

Ngokusebenzisa imibala eyahlukeneyo yemilomo, ungayijonga nje kancinci ukuba le mibhobho yeyeliphi inqanaba lokuhamba, elikugcinela ixesha lokukhetha imilomo kunye nokubala inqanaba lokuhamba. Kwintsimi yokhuseleko lwezityalo, sinenombolo enkulu yemilomo esinokukhetha kuyo. Ukuba ufuna ukwazi ngakumbi, nceda ukhululeke ukunxibelelana nathi
