Ua waikawa: ai hanganga

rerenga Waikawa (ua) - tetahi o nga ngā, i ahu rite ki te hua o te ahumahi.

parahanga Air me te ua takanga waikawa

Ki te rā, i reira te mea he whanaketanga tere o te ahumahi: te whakapaunga o ngā rauemi o te ao, wahie parariraa, me te te whanaketanga o te hangarau taiao hē. arata'i tenei tahuri i roto i ki te hau parahanga, te wai me te whenua. Ko tētahi taua faaiteraa he rerenga waikawa.

Ko te ariā o te waikawa "ua" i whakahuatia tuatahi i roto i 1872, engari kua riro tona hāngaitanga i roto i te hawhe tuarua o te rau tau whakamutunga. I te kau, ua waikawa - ko te raruraru nui mō te whenua maha i roto i te ao (tata katoa whenua Pākehā, me te United States). Kua whakawhanakehia ecologists ua he mahere e āta whakaatu te wāhi ki te mōrea nui o parataiao kino.

ihirangi hauhā i roto i te rangi

āhuatanga anake e te tetahi taumata o te kawatanga. I raro i ngā āhuatanga noa, kia hāngai tenei taupū ki te taumata kūpapa o te pH (i 5.6 - 5.7 me te he nui teitei). He kawatanga iti ko te hua i roto i te rangi o te te hauhā. Heoi, ko reira na iti e ko reira e taea e kore ki te meinga kino ki kaiao ora. Huri i te reira i roto i taua e pā ana te take o te ua waikawa ki mahi a te tangata, e kore e taea e ngā āhuatanga māori whakamārama reira.

Ko te takanga o te ua waikawa

i hanga e te hohenga waikawa rite ki te hua o te pira hinonga nui moni o waikura hauota me waikura whanariki.

Ko te puna o taua poke he tipu mana waiariki, rino, me te rino production, me nga hau whakapau o waka. horoi hangarau he taumata tino iti o taua tātari e kore e tukua te hauota, me te whanariki pūhui, hua i te parariraa o te Peat, waro, me te tahi atu rauemi mata whakamahia i roto i te ahumahi. Kia i roto i te huru, ngā waikura ki te wai kia rite ki te hua o ngā tauhohe piri e te rā. I muri i taua, hinga ratou rite te ua, kua karangatia e ratou "ua waikawa".

Pānga o te ua waikawa

Scientists tautohe e he tino kino hoki te tipu, kararehe, me te tangata ua waikawa. Ko te taketake tino o te ati i raro:

- ēnei ua tino whakanui i te kawatanga o wai, ahakoa awa, harotoroto awa ranei. Ka rite ki te hua, i reira ko te ngaro o te wao nui tūturu me otaota. taui hauropi Faarii, ko to ratou blockage, mākū, whakanuia ana sliminess. I muri i enei huringa te wai he ere i hoki te whakamahi tangata. faarahi te reira i te nui o tai whakarewa taimaha, me te whānuitanga o ngā pūhui paitini e kua riro e te microflora o te awa ki roto i ngā āhuatanga noa.

- enei ua ko te putanga o te ngaro o te tipu, me te ngahere kinonga. Conifers whiwhi te nuinga. Ko te meka e whakahoutia ratou rawa āta rau, a e kore e hoatu i te reira ratou i te whai wāhi ki te whaiaro ora-i te ua waikawa. He Young ngahere ano hoki i haria ki tenei tukanga, me te tere heke ratou kounga. arata'i papatipu waipara nui ki te whakangaromanga o ngahere.

- I roto i Europe a US te ua waikawa - te take matua o te kotinga rawakore, me te te ngaro o te kai ahuwhenua i roto i te mara. Meinga o te kino takoto i roto i te rongo tonu ki te ua e kore e anake, engari ano hoki i roto i te ofatiraa o te mineralization oneone.

- urupa Architectural, ngā whare, me te hanganga mamae hoki i te ua waikawa. Ka rite ki te hua o tenei tītohunga ko te tukanga waikura te nui whakatere, kore tikanga.

- I roto i ētahi wā, ka taea e ua waikawa meinga kino tūnguru ki te tangata me te kararehe. A, no te e koe i roto i ngā wāhanga o nui haere ati, timata ratou ki te whakakorikoria te mate wahi romahā o runga. Ki te haere tonu te reira, te reira hohoro rite rerenga ka hinga pākawa me ferrous kukū waikawa rawa tiketike. I roto i tenei take, kei te tino nui haere te riri o te ora tangata.

Ko te whawhai ki te ua waikawa

O te akoranga, e kore e haere ki te natura - taea ki te mahi ki te pea nā. Maturuturu atu i roto i nga mara, me ētahi atu wāhi nui, ua waikawa ai kino tina heke, a kahore e otinga whaitake ki tenei raruraru te tīariari. Ko reira tino tetahi i te mea e tika ana ki te tango kore ratou mau hopearaa, me take o. Ki te karo i te hanganga o te ua waikawa, e hiahia ana koe ki te tonu kawe i te maha o ngā ture: he waka huarahi taiao, me te haumaru, motuhake tikanga horoi tukunga, ngā hangarau production hou, puna o te pūngao, me te tahi atu production kē.

Humanity he kore mauruuru te mea kua ia. whakamahi tatou katoa nga rauemi ta'efakangatangata o to tatou paraneta, e whakapoke a kahore e hiahia ki te whakaae ki te mau hopearaa. A ko reira mahi a te tangata arahina whenua ki te kāwanatanga taua. Ko te tino kino tenei, no te mea ki te kore e tīmata tatou tango tiaki o koutou ao, ka riro i te pānga catastrophic.
