Phetoho ea maemo a leholimo
Ho futhumala ha lefatše le phetoho ea maemo a leholimo li ama boemo ba maoatle. Ka lebaka la keketseho ea selemo le selemo ea mocheso oa likhato tse 2 tsa Celsius, leqhoa lea qhibiliha, boemo ba Leoatle la Lefatše boa phahama, 'me, ka lebaka leo, bophahamo ba leoatle bo phahama, bo lebisang ho likhohola le khoholeho ea leoatle. Lilemong tsa lekholo la bo20 la lilemo, karolo e fetang halofo ea mabopo a lehlabathe lefatšeng e sentsoe.
E 'ngoe ea litlamorao tsa phetoho ea maemo a leholimo ke ho ba matla, khafetsa ha lifefo le keketseho ea sekhahla sa metsi. Sena se senya maphelo a batho ba lulang lebopong la leoatle. Liketsahalo tse matla tsa tlhaho li lebisa likoluoeng tsa tikoloho, ka lebaka leo eseng matlo a senyehang feela, empa le batho ba ka shoa.
Boima ba tšebeliso ea mobu
Mekhoa ea ho falla e na le tloaelo ea hore batho ba fallela libakeng tse kholo, empa ba lebopong. Ka lebaka leo, palo ea batho ba mabopong e ea eketseha, lisebelisoa tsa leoatle le sekhahla sa lebopong li sebelisoa haholoanyane, mme mojaro o moholo naheng oa hlaha. Bohahlauli bo ntse bo atleha metseng e haufi le leoatle, e leng se eketsang tšebetso ea batho. Sena se eketsa boemo ba tšilafalo ea metsi le lebopo ka bolona.
Tšilafalo ea maoatle
Ho na le mabaka a mangata a ts'ilafalo ea maoatle, haholo-holo maoatle. Libaka tsa metsi li na le tšilafalo ea malapa le metsi a litšila ka tlase ho indasteri.
