I-EX-VG hpht iphathwe idayimani yoxinzelelo oluphezulu lwedayimani yobushushu obuphezulu
iidayimani eziphathwa nge-hpht zidalwe kwindawo ezilawulwa kakhulu kwilebhu eziphinda-phinda iimeko apho idayimani ikhula ngokwendalo xa isenziwa kwimantle yomhlaba. Le meko-bume elawulwayo yenza kube nokwenzeka ukudala eyona ndlela inyulu yedayimani (99.99% yekhabhoni esulungekileyo) enobumdaka obumbalwa kwaye iziphene kunamatye atsalwe emhlabeni, ukwenza idayimani ezikhule elebhu zibe mhlophe, ziqaqambe ngakumbi kwaye zomelele kuneidayimani ezininzi zombiwe.
