I ka pili ʻana me ka hoʻomehana honua ma ka Honua, hiki ke hoʻoheheʻe nui ʻia o ka hau hau, ʻo ia ke kumu o ka piʻi ʻana o ka pae o ka moana honua. ʻAʻole ʻike ʻia ka lōʻihi o kēia hana. Wahi a kekahi mau kumuwaiwai i nā makahiki he 50 e hiki mai ana, e lilo ka moana o ka honua i ʻekolu mika ka hohonu. No laila, i kēia manawa, hiki i kahi mau kahakai ke loli i ka wā ʻino a me ke kai.
ʻO ka hapa nui o nā noiʻi e pili ana i kēia pilikia i mālama ʻia i mea e hoʻopaʻa ai i ka hopena o nā hopena i nā kānaka a me ko lākou kaiapuni. Eia nō naʻe, ua aʻo maikaʻi ʻole ʻia nā pilikia e pili ana i ka hopena o ka piʻi ʻana o ke kai ma luna o nā lau kai a me nā holoholona. Eia kekahi, noho ka honu kai i ka hapa nui o ko lākou ola i ka wai, akā pono lākou e hele i uka i kēlā me kēia manawa e hoʻomoe i kā lākou mau hua. He aha ka hana ke hiki aku ka wai i nā hua manu ma kahakai one?
Ua loaʻa nā hihia i ka wā i hoʻopiha ai ka wai kai i nā pūnana manu kuhukukū a i ʻole nā keiki hānau hou. ʻAʻole ʻike ka ʻepekema i nā hopena o ka hoʻolōʻihi ʻia ʻana i ka wai paʻakai ma nā hua. ʻO nā ʻepekema mai ke Kulanui ʻo James Cook (ma Townsville, Australia), ma lalo o ke alakaʻi a Professor David Pike, i hōʻiliʻili ai i nā hua manu kuhukukū no ka noiʻi ʻana ma ka Pae ʻo Great Barrier Reef. Ua hana ʻia nā ʻano i loko o ke keʻena hoʻokolohua e hoʻopuka ai i ka wai paʻakai o ke kai, a hōʻike ʻia nā pūʻulu mana o nā hua i nā lōʻihi like ʻole. Ua hoʻokuʻu ʻia nā hopena noiʻi ma Iulai 21, 2015.
Ma hope o ka mālama ʻia ʻana o nā hua i loko o ka wai paʻakai no hoʻokahi a ʻekolu mau hola, ua hoʻemi ʻia ko lākou hiki ʻana e 10%. ʻO ka noho ʻeono mau hola o ka pūʻulu kaohi i nā hana i hana ʻia i hana ʻia e hōʻemi i nā mea hōʻike i 30%.
ʻO ka hana hou o ka hoʻokolohua me nā hua like i hoʻonui i ka hopena maikaʻi ʻole.
I loko o nā honu keiki i hū ʻia, ʻaʻohe hoʻololi i ka hoʻomohala ʻana, eia naʻe, e like me ka mea noiʻi, i mea e huki ai i nā hopena hope, pono e hoʻomau ʻia ke aʻo ʻana.
ʻO ka nānā ʻana i ka hana a me ka hana nui o nā honu ʻōpio e pane i nā nīnau pehea ka hopena o ka hypoxia (pōloli oxygen) i nā holoholona a pehea e loli ai kēia ola ʻana.
Ke hoʻāʻo nei kahi hui ʻepekema e alakaʻi ʻia e David Pike e loaʻa ka manaʻo o ka pilikia e pili ana me ka momona o nā honu kai ʻōmaʻomaʻo ma ka mokupuni ʻo Rhine ma ka Great Barrier Reef.
Loaʻa kēia mau hōʻailona mai 12 a 36%, ʻoiai kēia ʻano o nā honu ka mea maʻamau no nā keiki mai 80% o nā hua i kau ʻia. Ma muli o ka noiʻi i mālama ʻia mai ka makahiki 2011, ua hoʻoholo ka poʻe ʻepekema i ka hopena nui o ka emi ʻana o ka heluna kanaka i ka ua a me nā kahe wai, ma muli o ka hopena o ka wai i ka moku.
