North America - mavuto a zachilengedwe. mavuto Environmental wa America North

Environmental vuto - kuwonongeka kwa chilengedwe, kugwirizana ndi kungasokoneze khalidwe achilengedwe, ndi lero kungathandize kwambiri ndi chinthu anthu. Zikutha m'mayiko ozoni, kuipitsa kapena chiwonongeko - zonsezi, mwanjira ina, zinkatanthauza mavuto aakulu tsopano ndi m'tsogolo.

North America, ndi mavuto a zachilengedwe zomwe zofunika kwambiri, ndi nkhani ya chitetezo zachilengedwe ndi pachimake kwambiri, ndi limodzi mwa madera ambiri pang'onopang'ono kwa dziko. Chifukwa cha kutukuka kwa US ndi Canada ndi nsembe chikhalidwe chake. Chotero kodi mu mavuto chitetezo zachilengedwe anakumana ndi anthu a America North ndi mmene kuopseza m'tsogolo?

patsogolo zamakono

Choyamba tisaiwale kuti nthawi kuvutika mikhalidwe ya moyo wa m'tawuni, makamaka malo mafakitale. Chifukwa cha ichi ndi masuku pamutu yogwira zachilengedwe - nthaka, pamwamba madzi, mpweya ndi chilengedwe, kuwononga zomera. Komabe, limasonyeza zofunika kwambiri chilengedwe - nthaka, hydrosphere ndi mpweya - ndi inakula, ndi zimakhudza anthu pa aliyense wa iwo ankaganizira za ena, kotero njira zowononga kukhala padziko lonse.

Pamene osauka North America, mavuto Africa zachilengedwe akukhala kovuta. Wogawana patsogolo ndi chiwonongeko ndi kusamutsidwa kwa malo achilengedwe ndi m'malo ake wotsatira ndi chilengedwe yokumba, amene angathe kukhala wowopsa ndipo ngakhale zosafunika pa moyo wa munthu. Pakuti theka lachiwiri la misa XX m'ma zinyalala pa America North anali biliyoni 5-6. Tonnes pa chaka, zimene osachepera 20% anali zotakasika.

utsi

utsi vuto lero enieni padziko lonse, koma kugombe la kumadzulo kwa United States mu California zinthu makamaka aakulu. Mu malo awa pamodzi Chile akudutsa otaya ozizira, umene ndi madzi a m'mphepete mwa nyanja kumaundanitsa nthunzi, amene simuvutika mabuku lalikulu mpweya utsi wa magalimoto. Komanso, nthawi yachilimwe theka la chaka ndi ofunika nyengo anticyclonic abwino utithandize kuchuluka cheza dzuwa, chifukwa mu chikhalidwe cha likufa masinthidwe mankhwala zovuta. Chifukwa cha ichi ndi chifunga wandiweyani, mmene misa nsanganizo za poizoni.

Akatswiri kuphunzira mavuto a zachilengedwe a North America, wotchedwa kwambiri utsi mpweya kovuta kwambiri kwa anthu, chifukwa sali zikuwononga yekha bwanji chikhalidwe, komanso chifukwa cha matenda ambiri anthu.

Wakuta ka madzi

Koma pali nkhani zina zachilengedwe ku North America? Kumtunda, lero zinthu kwambiri ndi madzi - iwo ali chabe wotopa. Pa Africa sanali kusiya kukula mowa madzi, ndi lero kale kuposa kololeka. Ngakhale m'zaka za m'ma aphedwa, American katswiri A. Uolmenom lofalitsidwa zotsatira kafukufuku, chimene oposa theka a anthu US amadya madzi, ntchito kamodzi ndipo anadutsa sewers lapansi.

Izi zikachitika, zimakhala zovuta kuchita awiri zinthu zofunika kwambiri: Kuwonjezera khalidwe madzi kubwezeretsa m'pofunika kosalekeza kuonetsetsa kuti buku zachilengedwe ku mitsinje ndi matupi zina madzi. Mu 2015, ndi mosungiramo yaikulu ya dziko mwamphamvu utachepa madzi, ndi asayansi kuchenjeza kuti izi zikhoza kukhala chiyambi cha chilala yaitali.

kuipitsa madzi

Izo si yekha wakuta wina mavuto a zachilengedwe mitsinje ya North America. Mndandanda wa zinthu zoipa mderali motalika kokwanira, koma makamaka kuipitsa madzi. Iwo kutaya wa zinyansi zimene chilichonse angapezeke, kuchititsa kuwonongeka kwakukulu ndi kutumiza.

Komanso lero, kuwononga zinthu zambiri amayambitsa matenthedwe kuipitsa. Pafupifupi gawo limodzi la madzi achoka mitsinje chaka, chifukwa zomera mphamvu za nyukiliya ndi ikukhudzana kumene ndi mkangano n'kubwerera posungira. madzi apamwamba kutentha ndi 10-12% ndipo zili mpweya kwambiri m'munsi, amene n'chofunikira kwambiri ndipo nthawi zambiri chifukwa cha imfa ya zamoyo zambiri.

Kale mu theka lachiwiri la m'ma XX mu United States chaka chilichonse kuipitsa madzi zatha 10-17 mln. Species ya nsomba ndi Mississippi ndi mtsinje waukulu ku North America, lero mmodzi wa khumi kwambiri wowonongeka dziko.

Ena a chikhalidwe

malo wapadera ndi wolemera kwambiri nyama ndi zomera ili pafupifupi M'madera a zitunda Chigawo North America. mavuto Environmental zafika ndi chikhalidwe pristine m'dzikoli. Pa m'gawo lake pali ambiri malo osungirako zachilengedwe, zomwe akhala mu masiku ano pafupifupi m'madera yekha, kumene anthu ambiri m'mizinda athawe ku phokoso ndi dothi mizinda. The kuchuluka kwa alendo komanso alendo, kukula ndi liwiro zosaneneka, zokhudza awo bwino zachilengedwe, chifukwa cha zomwe lero ena wapadera zomera ndi nyama zamoyo ndi pa zobvuta kutha.

N'zomvetsa chisoni kuti osati mwamuna ndi gwero la kuipitsidwa - anasambitsidwa ndi Madzi a mvula ndipo lotengeka ndi mphepo, ndipo kenako anasamukira ku mtsinje zinthu zosiyanasiyana poizoni ali zinyalala thanthwe. milu Zimenezi zingakuthandizeni kutambasula pamodzi ndi bedi mtsinje pa mtunda wautali, zonse kuchotsako dziwe.

Ngakhale kumpoto Canada, kumene zachilengedwe akupangidwa si monga kwambiri lero, muona atasintha mu chikhalidwe. mavuto Environmental nayonso mu North America kuphunzira antchito Wood Buffalo, mmodzi wa m'mapaki waukulu dziko lonse lapansi.

Litha

Monga tanenera kale, mavuto a zachilengedwe a Africa makamaka zokhudzana ndi mkulu wa sayansi mlingo wa chitukuko cha USA ndi Canada. zachilengedwe a North America zosiyanasiyana komanso ambiri: matumbo m'dzikoli wolemera mu mafuta, gasi, mchere wofunika. nkhokwe yaikulu nkhuni kumpoto ndi abwino ulimi m'dziko kum'mwera kwa zaka zambiri ntchito kwambiri intensively, umene unali chifukwa cha mavuto ambiri zachilengedwe.

gasi shale

Posachedwapa, panali kukomeza zazikulu shale mpweya - amabala zambiri kwambiri North America. mavuto Environmental omwe angagwe ntchito njira zamakono ena, nkhawa zikuoneka pang'ono kwambiri makampani chinkhoswe pa zokambiranazi ndi kupanga chimasanduka ku formations shale. Mwatsoka, ndale amagwira nawo ntchito kulimbikitsa mtundu wa kupanga mphamvu, ndipo zotsatira zotheka kwa chilengedwe, ndi zina konse n'komwe. Motero, boma US anatengera mfundo za kusadalira amapereka mphamvu kwa misika ya kunja, ndipo ngati dzulo dziko akugula mpweya kuchokera loyandikana Canada, lerolino ali pabwino wokha ngati State wa katundu wa chimasanduka. Ndipo zonse izi likuvutika chilengedwe.

Mawuwo m'tsogolo

M'nkhani ino yochepa ine kukambirana mwachidule nkhani zachilengedwe ku North America. Zonse zomwe ife, ndithudi, anali suona, koma pamaziko a chuma, angathe Ndizachidziwikire kuti kufuna phindu ndi kufunafuna zinthu zakuthupi anthu methodically ntchito ndi kupitiriza kuwononga kwambiri chilengedwe, pamene kawirikawiri kuganiza za zotsatira za zochita zawo.

Akuyesera kuti akwaniritse zotsatira pazipita mu masuku pamutu zachilengedwe, ife kuwaŵerenga zodzitetezera, ndipo tsopano tili ndi zimene tili nazo. Chitsanzo fanizo izi - ndi North America, mwina dera koposa anayamba wa dziko, mavuto a zachilengedwe zimene zili kwambiri ndithu.
