I ngā tau tata nei, kua nui haere te aro o te tangata ki te hauora me te tiaki i te taiao, ā, kua piki haere te rongonui o te muka tipu. Kua hoki anō te aro o te umanga kakahu ki te muka panana.
Ko te panana tētahi o ngā hua tino pai ki te tangata, e mōhiotia ana ko te "hua harikoa" me te "hua o te whakaaro nui". E 130 ngā whenua e whakatipu ana i te panana i te ao, ko Amerika Waenganui te whenua nui rawa atu e whakaputa ana, ā, ko Āhia te whenua whai muri. E ai ki ngā tatauranga, neke atu i te 2 miriona tana o ngā rākau panana e makahia ana i ia tau i Haina anake, ā, he nui te maumau rauemi. Heoi, i ngā tau tata nei, kāore i makahia ngā rākau panana, ā, kua noho hei kaupapa wera te whakamahinga o ngā rākau panana hei tango i te muka kakahu (muka panana).
He mea hanga te muka panana mai i te kakau o te panana, ko te nuinga he cellulose, he haurua-cellulose me te lignin, ka taea te whakamahi mō te miro miro i muri i te tihore matū. Mā te whakamahi i te tukanga maimoatanga whakakotahi o te whākōkī koiora me te waikura matū, mā te whakamaroke, te whakamahine, me te whakahekenga, he mārama te kounga o te muka, he kanapa pai, he mimiti nui, he kaha ki te patu huakita, he ngāwari te whakaheke me te tiaki i te taiao me te maha atu o ngā mahi.
Ehara i te mea hou te hanga papanga me te muka panana. I Hapani i te tīmatanga o te rautau 13, i hangaia te muka mai i ngā kakau o ngā rākau panana. Engari i te pikinga ake o te miro me te hiraka i Haina me Īnia, kua ngaro haere te hangarau hanga papanga mai i ngā panana.
Ko te muka panana tētahi o ngā muka tino kaha o te ao, ā, he tino pakari tēnei muka taiao pirau-ora.
Ka taea te hanga muka panana hei papanga rerekē i runga i ngā taumaha me ngā matotoru rerekē o ngā wāhanga rerekē o ngā kakau panana. Ko te muka totoka me te muka matotoru ka tangohia mai i te anga o waho, ko te anga o roto ia ka tangohia mai i ngā muka ngohengohe.
E whakapono ana ahau ā tōna wā, ka kite tātou i ngā momo muka panana katoa i hangaia ki ngā kākahu i roto i te toa hokohoko.
