ʻO ka hopena o nā mea hana e waiho ana ma keʻano a me nā kumuwaiwai
ʻO nā mea waiwai ke kumu a me ke kumu mua o ka hoʻokele waiwai a me ka hoʻomohalaʻana. In the process of material harvesting, extraction, preparation, production, processing, transportation, use and disposal, on the one hand, it promotes social and economic development and the progress of human civilization, on the other hand. Hoʻohanaʻia ia i ka nui o ka ikehu a me nā kumuwaiwai, a e hoʻopau i ka nui o ka wai wai, nā wai wai a me ka pauʻole o ke olaʻana o ke kanaka. Hōʻike nā helu helu likeʻole, mai ka hoʻopaʻaʻana i ka nui o ka ikaika a me nā kumuwaiwai o ke kumukuai o ka honua Me ka pōmaikaʻi o nā waiwai a me ka wikiwiki o ka rapid o kaʻoihana hana, e kū pono ana i nā mea hana e like me ka pilikia like. Wahi a nā helu heluʻole, i kēia manawa no kēia manawa no kēia manawa no ka hanaʻana o nā mea hana i loko o ke ao nei he 145kg i kēlā me kēia makahiki. Ma waena o 600 miliona mau hōʻailona o ka wai a me nā mea paʻa i hanaʻia i ka honua i kēlā me kēia makahiki he 16 miliona mau manawa, e pili ana i ka nui o ka nui o ke kūlanakauhale āpau. 15% o ka nui. He mea hoʻohālikelike ia e like me kahi helu kupaianaha e alakaʻi i ka haumia o ke kaiāulu koʻikoʻi a me ka pauʻole o nā kumuwaiwai i ka lōʻihi lōʻihi. Ma keʻano kūikawā,ʻo ka "element keʻokeʻo" i hanaʻia e ka palpika pepa i hikiʻole ke hoʻokaʻawaleʻia no 20000 mau makahiki 400.
