Tikoloho ea Arctic e senyeha habonolo, empa boemo ba tikoloho ea mahoatata a Arctic bo ama maemo a leholimo a lefatše, ka hona ha mathata afe kapa afe a hlaha mona, batho ba likarolong tse fapaneng tsa lefats'e ba ka a utloa. Mathata a tikoloho ea mahoatata a arctic a siea matšoao a bona tikolohong ka kakaretso.
Mathata a maholo
Haufinyane, libaka tsa mahoatata a arctic li ntse li etsa liphetoho lefatšeng ka bophara ka lebaka la tšusumetso ea anthropogenic. Sena se hlahisitse mathata a latelang a tikoloho Arctic:
- Leqhoa le qhibilihang. Selemo se seng le se seng mocheso oa phahama, maemo a leholimo a fetoha le sebaka sa lehloa se ntse se fokotseha, ka hona sebaka sa tlhaho sa mahoatata a Arctic se ntse se fokotseha ka mafolofolo, se ka lebisang ho nyameleng ha sona ka botlalo, ho fela ha mefuta e mengata ea limela le liphoofolo.
- Tšilafalo ea moea. Boholo ba moea ba Arctic bo ntse bo silafala, bo tlatsetsang ho pula ea asiti le masoba a ozone. Sena se na le phello e mpe bophelong ba lintho tse phelang. Mohloli o mong oa tšilafalo ea moea mahoatateng a Arctic ke lipalangoang tse sebetsang mona, haholo nakong ea merafo.
- Tšilafalo ea metsi a Arctic a nang le lihlahisoa tsa oli, tšepe e boima, lintho tse chefo, litšila tsa mabotho a sesole sa leoatle le likepe. Tsena tsohle li senya tikoloho ea mahoatata a arctic
- Fokotseha ho liphoofolo le linonyana. Ho fokotseha ha mefuta-futa ea limela ho bakoa ke mesebetsi e matla ea batho, ho tsamaisa likepe, metsi le tšilafalo ea moea
- Tlhahiso e mafolofolo ea tlhahiso ea ho ts'oasa litlhapi le ea tlhapi ea leoatleng e lebisa ntlheng ea hore baemeli ba fapaneng ba lefats'e la liphoofolo ha ba na litlhapi tse lekaneng le li-plankton tse nyane bakeng sa lijo, mme ba bolaoa ke tlala. E boetse e lebisa ho timeleng ha mefuta e meng ea litlhapi.
- Liphetoho tikolohong ea lintho tse phelang tse fapaneng. Ponahalo ea motho boteng ba lehoatata la Arctic, nts'etsopele e sebetsang le ts'ebeliso ea tikoloho ena e lebisa ntlheng ea hore maemo a bophelo a mefuta e mengata ea liphoofolo a fetoha. Baemeli ba bang ba qobelloa ho fetola libaka tsa bona tsa bolulo, khetha libaka tse sireletsehileng le tse ling tse hlaha. Moketane oa lijo le ona oa senyeha
Lethathamo lena ha le felle palo ea mathata a tikoloho tikolohong ea lehoatata la Arctic. Tsena ke mathata a mantlha a tikoloho le tikoloho, empa ho boetse ho na le a manyane, a lehae, le a seng kotsi joalo. Batho ba tlamehile ho laola mesebetsi ea bona eseng ho senya tlhaho ea Arctic, empa ho e thusa ho e khutlisa. Qetellong, mathata ohle a mahoatateng a Arctic a ama boemo ba leholimo ba lefatše ka bophara hampe.
Ho sireletsa tlhaho ea mahoatata a arctic
Kaha tikoloho ea mahoatata a Arctic e susumelitsoe hampe ke batho, e hloka ho sireletsoa. Ka ho ntlafatsa boemo ba Arctic, ecology ea Lefatše lohle e tla ntlafala haholo.
E meng ea mehato ea bohlokoahali bakeng sa paballo ea tlhaho ke e latelang:
- theho ea puso e khethehileng bakeng sa ts'ebeliso ea lisebelisoa tsa tlhaho;
- ho hlokomela boemo ba tšilafalo ea tikoloho le tikoloho;
- tsosoloso ea libaka tsa naha;
- theho ea libaka tsa polokelo ea tlhaho;
- botjha botjha;
- mehato ea ts'ireletso;
- palo e eketsehang ea liphoofolo le linonyana;
- taolo ea ho ts'oasa lihlapi tsa indasteri le ho tsoma hampe naheng.
Liketsahalo tsena ha li etsoe feela ke litsebi tsa tikoloho, empa hape li laoloa ke mmuso, mme baetapele ba linaha tse fapaneng ba nts'etsapele mananeo a ikhethang. Ntle le moo, ho na le sehlopha se arabelang hanghang se sebetsang maemong a likotsi tse fapaneng, likoluoa, tsa tlhaho le tse entsoeng ke batho, ho felisa sepheo sa bothata ba tikoloho le nako.
Sebetsa ho sireletsa tikoloho ea Arctic
Tšebelisano 'moho ea machabeng e bohlokoa haholo bakeng sa paballo ea tlhaho ea mahoatata a Arctic. E ile ea matlafala lilemong tsa bo-1990. Kahoo linaha tse ling Amerika Leboea le Europe Leboea li ile tsa qala ho sebetsa 'moho ho sireletsa tikoloho ea Arctic. Ka 1990, Komiti ea Machabeng ea Saense ea Arctic e thehiloe ka morero ona, mme ka 1991, Foramo ea Leboea. Ho tloha ka nako eo, ho entsoe maano a ho sireletsa sebaka sa Arctic, libaka tsa metsi le mobu.
Ntle le mekhatlo ena, ho boetse ho na le mokhatlo oa lichelete o fanang ka tšehetso ea lichelete ho linaha tsa Europe Bochabela le Bohareng ho rarolla mathata a tsona a tikoloho. Hona le mekhatlo ea linaha tse 'maloa e sebetsanang le ho rarolla bothata bo itseng.
- ho boloka palo ea libere tsa polar;
- ho loantša tšilafalo ea Leoatle la Chukchi;
- Leoatle la Bering;
- taolo ea ts'ebeliso ea lisebelisoa tsa sebaka sa Arctic.
Kaha sebaka sa mahoatata a Arctic ke sebaka se amang haholo boemo ba leholimo ba Lefatše, tlhokomelo e tlameha ho nkuoa ho boloka tikoloho ena. Hona ha se feela ntoa ea ho eketsa palo ea liphoofolo, linonyana le litlhapi. Boima ba mehato ea ts'ireletso ea tikoloho e kenyelletsa tlhoekiso ea libaka tsa metsi, sepakapaka, phokotso ea ts'ebeliso ea lisebelisoa, taolo ea mesebetsi ea likhoebo tse ling le lintho tse ling. Bophelo ba Arctic bo ipapisitse le sena, ka lebaka leo, maemo a leholimo a lefatše.
