Izinsiza yemvelo

izinsiza eziphilayo (BR) kuyimithombo Lokudabuka ophilayo anomthelela ukusetshenziswa womuntu zezinto zokusebenza, isibonelo, ukudla impahla for umkhakha, zokuzalanisa izitshalo, izilwane nezinto ezincane eziphilayo. Lamasu ebalulekile abantu imvelo variable futhi ethulwa ngesimo phakathi kwezitshalo, izilwane, ama-bacterium, kanye nemvelo (amahlathi, imvelo amanzi nabanye).

Kufanele kuqashelwe ukuthi zonke izinto eziphilayo unekhono kabusha, yingakho imithombo yemvelo avuselelwa, kubalulekile kuphela ukulondoloza izimo elilungele leli. Kuze kube manje, ukusetshenziswa yesimanje BR uhlelo kungabangela ukuqedwa enkulu ingxenye yalo.

Ingxenye esemqoka ye-BR ewela izitshalo ihlathi, sibonga esinakho ¼ yokwanda yonyaka e wezinto zokubasa. Okwamanje, izinto ezenziwa abantu ziye zaholela yokuthi isibalo ophilayo ndaba yehlile, ngakho umkhiqizo Umhlaba begazi kwehle. Nokho, ngokufaka esikhundleni ingxenye yamahlathi zangaphambili emadlelweni, abantu, ngaleyo ndlela, ukudla nendawo lobuchwepheshe impahla ebomvu labantu emhlabeni.

Kuze kube manje, umhlaba yefomu ihlathi esishintshashintshayo ezimbili: i-South (lezihlahla zemithi) nenyakatho (AmaConifers). Labo amazwe ukuthi akudingeki izindawo ihlathi uhlushwa ukuntuleka kwezinsiza ihlathi.

Okwamanje, ihlathi imithombo yemvelo yeRussia, eCanada, e-United States ne-Brazil kukhona ngobukhulu. Le ndawo yamahlathi eningizimu uqale zinyamalale ngenxa ukwanda emazweni angaphandle ngokhuni futhi ulisebenzise njengoba uphethiloli, kuyilapho ibhande ihlathi sulphur ahlale injalo ingashintshile. Kodwa naphezu kwalokhu, lezi zinsiza zikhulisa njalo ngonyaka.

izinsiza eziphilayo, okungukuthi ukudla, akha amaphesenti angu-amabili ukukhiqizwa Imininingwane wezolimo, futhi amaphesenti omunye umkhiqizo ingqikithi ulwandle nezwe. Kufanele kukhunjulwe ukuthi ngenxa ukwanda okusheshayo kwenani labantu, ukukhiqiza imikhiqizo kwezitshalo kumele lenyuke kabili, ngenkathi imikhiqizo imfuyo - kathathu. Ngakho, kubalulekile ukuthuthukisa ezolimo, ezolimo eniselwayo, ukusetshenziswa okunengqondo ocean imithombo.

izinsiza eziphilayo olwandle akhawunti amathani kwezigidi eziyikhulu, zazo amaphesenti amabili ishiywa ekululameni kwakhe. Yonke imikhiqizo ethulwa ngesimo kanye nezinhlanzi izindawo; Amazwe amaningi bekwi okuthiwa ama-sea ukulima, ukuzalaniswa kwamahhashi ulwelwe, molluscs, ulwandle ukhukhamba nenhlanzi.

Ngakho, isizinda lokuqala luthatha izinhlanzi (85%), bese - non-inhlanzi, kuhlanganise ulwelwe (9%), pinnipeds nemikhomo (6%).

Naphezu kweqiniso lokuthi abantu eMhlabeni likhula ngokushesha, okwandisa ukudoba njalo uya ngokushesha. Isidingo ukwandisa inani ekhiqizwa imizimba amanzi exhunywe kokubili umnotho nokuthi imithi, njengoba amaphuzu yokugcina isidingo ukudliwa ngabantu njalo kwasolwandle.

Noma kunjalo, akufanele sikhohlwe isidingo kabili ukukhiqizwa kwasolwandle.

izinsiza eziphilayo zomhlaba isilwane yinto eyigugu emhlabeni wonke, ngoba izilwane ukunikeza ubumsulwa imizimba yamanzi, inhlabathi okuzala, impova izimbali nokunye.

Kuze kube manje, abameleli abaningi nezilwane ezisengozini yokushabalala. Nokho, kufanele kusho ukuthi kukhona namanje ezindaweni eziningi emhlabeni ezingazange wafunda, kanye namaqembu amaningi eziphilayo. Ngaphezu kwalokho, uma umuntu ebhema kuphela ingxenye encane lezinto zemvelo, kanye nemvelo eziningi ukuzisekela.

Ngakho, BR zimelela yonke izinto bukhoma kusukela uHlu Jikelele Lwamakheli, akha imvelo.
