ʻO ka hoʻomaʻamaʻa ʻana i ka wai punawai e kū ana i nā manawa mākeke 

    I kēia manawa, nui nā pūnāwai wai ma Kina i nā pae like ʻole o ka maikaʻi o ka wai. ʻOi loa i ka wā e hōʻiliʻili ʻia ai nā mea organik, phosphorus, nitrogen a me nā mea ʻē aʻe i loko o ka wai, e hoʻoikaika lākou i ka hoʻolaha wikiwiki ʻana o nā algae, aʻo ka algae e hoʻopau i ka oxygen i loko o ka wai i ka wā o ka ulu a me ka ulu ʻana. E hana i ka wai eutrophic. ʻO ke kumu o ka eutrophication ʻaʻohe hale mālama wai i loko o ke kino wai o ka ʻāina, a ʻo kahi hapa nui o ka pāhana wai punawai ʻaʻole i hoʻokomo ʻia i nā lako mālama wai i mea e mālama ai i ka hoʻopukapuka ʻana, no laila ʻaʻole hiki ke hoʻokō ʻia ka maikaʻi o ka wai o ke kolu a me ka ʻehā o ka wai ʻāina i kuhikuhi ʻia i nā lula. maʻamau. ʻOiai ua hoʻonani kēia mau papahana i ke kaiapuni holoʻokoʻa, ua hoʻohaumia pū lākou i ke kaiapuni ma kekahi ʻaoʻao.

ʻO ka hoʻohana ʻana i ka wai ua kūlanakauhale a me nā kumu wai maʻamau ua loaʻa ka manaʻo nui a me ka nānā ʻana mai nā wahi a pau o ka honua. ʻOi aku ma nā ʻāina i kūkulu ʻia, ʻo ka hōʻiliʻili a me ka hoʻohana ʻana i ka wai ua o ke kūlanakauhale ua hiki i kahi kiʻekiʻe, e like me Farani, Kelemānia, Iapana, Australia, Belgium a me nā ʻāina ʻē aʻe, ka hale a me ka lepo.
