Ngesikhathi sokuphila kwesintu, inani elikhulu kakhulu lezinhlobo zezitshalo selivele lanyamalala ebusweni bomhlaba. Esinye sezizathu zalesi simo izinhlekelele zemvelo, kepha namuhla kufanelekile ukuchaza le nkinga ngomsebenzi we-anthropogenic. Izinhlobo ezingavamile zezimbali, okungukuthi, izinsalela, zisengozini yokuqothulwa kakhulu, futhi ukusatshalaliswa kwazo kuncike emingceleni yendawo ethile. Ukudonsela ukunaka komphakathi, kwenziwa iBhuku eliBomvu, lapho kufakwa khona ulwazi ngezinhlobo zezilwane ezisengozini yokuqothulwa. Futhi, izinhlaka zikahulumeni zamazwe ahlukene zivikela izitshalo ezisengozini yokuqothulwa.
Izizathu zokunyamalala kwezitshalo
Ukunyamalala kwezimbali kwenzeka ngenxa yemisebenzi yezomnotho yabantu:
- ukugawulwa kwamahlathi;
- edlisa imfuyo;
- amanzi amaxhaphozi;
- ukulima kwama-steppes nezimfunda;
- ukuqoqwa kwamakhambi nezimbali ezithengiswayo.
Okungenani, imililo yamahlathi, izikhukhula ezindaweni ezisogwini, ukungcoliswa kwemvelo nezinhlekelele zemvelo. Ngenxa yezinhlekelele zemvelo, izitshalo ziyafa ngobuningi bazo ngobusuku obubodwa, okuholele ekuguqulweni kwemvelo emhlabeni jikelele.
Izinhlobo zezimbali ezingasekho
Kunzima ukuthola ukuthi mangaki amakhulukhulu ezinhlobo zezitshalo asenyamalele emhlabeni. Eminyakeni engama-500 edlule, ngokusho kochwepheshe be-World Conservation Union, izinhlobo ezingama-844 zezitshalo zanyamalala unomphela. Esinye sazo yi-sigillaria, izitshalo ezinjengezihlahla ezafinyelela ebangeni elingamamitha angama-25, zaba neziqu ezijiyile, futhi zakhula ezindaweni ezinamanzi Zikhule ngamaqembu, zakha izindawo ezigcwele zehlathi.
Sigillaria
Uhlobo oluthandekayo lukhule eziqhingini zasePacific Ocean - uStreblorisa ovela ohlotsheni lomdumba, waba nezimbali ezithakazelisayo. Okuqothulwe yiKriya violet, imbiza ekhule yaba ngamasentimitha ayi-12 futhi inezimbali ezibubende.

Futhi kusuka ezitshalweni ezinjengezihlahla, izinhlobo ze-lepidodendron zanyamalala, ezazimbozwe ngamahlamvu aminyene. Ezinhlotsheni zasemanzini, kufanelekile ukusho ulwelwe lwe-nematophyte, olutholakala emizimbeni ehlukahlukene yamanzi.
Lepidodendron
Ngakho-ke, inkinga yokunciphisa ukwehlukahlukana iyaphuthuma emhlabeni. Uma ungathathi isinyathelo, izinhlobo eziningi zezimbali zizonyamalala maduzane. Okwamanje, izinhlobo ezingavamile nezisengozini zifakwe kuRed Book, futhi ngemuva kokufunda uhlu, ungathola ukuthi iziphi izitshalo okungafanele zikhethwe. Ezinye izinhlobo zeplanethi cishe azikaze zitholakale, futhi zitholakala kuphela ezindaweni okunzima ukufinyelela kuzo. Kufanele sivikele imvelo futhi sivikele ukuphela kwezitshalo.
