Abantu abaninzi banenkxalabo malunga ngileyo bazama ukuthenga iimveliso ezinokutsha kuba bacinga ukuba abayi kuba nefuthe elibi kwindalo esingqongileyo, kodwa akusoloko kunjalo.
Imveliso enokuboliswa ziintsholongwane kufuneka ikwazi ukuthoba umgangatho kunyaka omnye kodwa ifuna iimeko ezithile ukuze yenzeke ngokuchanekileyo, njengendawo elahliweyo kuyo inayo ioksijini ukuze uqalise inkqubo yokuthotywa isidima.
Kwelinye icala, ukuba imveliso enokuboliswa ziintsholongwane iyalahlwa kwifayile ye- inkunkuma engenawo ioksijini njengoko kusenzeka ngaphakathi izigcayiseli Ukuthotywa isidima, kodwa ukuvelisa imethane, igesi engcolisayo kwaye omnye wabo unoxanduva lwe ukufudumala kwehlabathi.
El irhasi yemethane eveliswa kukuthotywa kwenkunkuma inokusetyenziswa kwaye ivelise amandla kodwa ukuba ikhutshelwe emoyeni iyangcolisa.
Kuninzi lweendawo zokulahla inkunkuma le methane ayifakwanga ngoko ke ivelisa ungcoliseko olukhulu lwendalo.
Ngokucacileyo kungcono ukusebenzisa nokusebenzisa iimveliso ezinokuboliswa ziintsholongwane kodwa oku akonelanga, kunyanzelekile ukuba kufunwe ukuba ezi nkunkuma ziphathwe ngokuchanekileyo ukuze zingangcolisi okufanayo.
Okubi Ulawulo lwenkunkuma Ingcolisa kakhulu kwaye le nyani yenzeka kwihlabathi liphela ukusukela oko bangcwatywa okanye batshiswa kwaye oku kuvelisa ukukhutshwa okubalulekileyo kwetyhefu kunye neegesi eziyingozi emoyeni.
Iimveliso ezinokuboliswa ziintsholongwane kufuneka zibekwe kwiindawo ezinokwenza umgquba kwaye zingayikhuphi imethane.
Kubalulekile ukuba njengabathengi sizame ukunciphisa ukusetyenziswa kweemveliso zeplastiki, iibhegi nokuba zi-100% ezinokuboliswa ziintsholongwane, kodwa zikwanyanzelisa ukuba abasemagunyeni benze ulawulo lwenkunkuma olufanelekileyo ukunqanda ungcoliseko.
Kufuneka sonke sisebenzisane ukunciphisa isixa se inkunkuma kwiplanethi kunye nokuthatha inxaxheba ekubuyiseleni uninzi lwazo ukuze kamva ziphinde zisetyenziswe okanye zonakaliswe ngendlela efanelekileyo.
