IPlanethi yoMhlaba iyamangalisa. Nangona sahlulwe ngamazwekazi, kwaye nangona sahlukane ngamawaka eekhilomitha, okwenzekayo apho sihlala khona kunokuba nefuthe kwilizwe lonke. Ayisiyiyo loo nto kuphela, kodwa kwinto esinokubonakala ngathi ngumhlaba ohlwempuzekileyo kwizakhamzimba, kwezinye izityalo sesona sichumisi sihle ehlabathini.
Ngophando olwenziwe zizazinzulu kwiYunivesithi yaseMichigan, UC Merced, kunye neYunivesithi yaseWyoming, I-Redwoods ekhula eSalifornia Nevada yaseCalifornia ichunyiswa ngothuli oluvela kwiNtlango yaseGobi, olusuka kumantla eTshayina luye eMongolia.
I-redwoods yaseCalifornia ihlala kwindawo apho i-phosphorus yenye yezona zinto zisezantsi emhlabeni. Le minerali ibaluleke kakhulu kwizityalo, hayi kwezi zinto zinkulu kakhulu, kodwa nakwezinye izityalo, kuba ngaphandle kwayo ngekhe zikhule kakuhle kwaye ziya kugqibela ngokufa.
Ngethamsanqa ngomthi obomvu kunye nezinye izityalo ezihlala nabo, uthuli lwasentlango lwaseGobi, lwakuba lubekwe emhlabeni, kunye nemvula i-phosphorus equlethweyo iyafumaneka kwizityalo, eziyifunxa ngeengcambu zazo.
Iingcali zikholelwa ekubeni, nangona intlango iqhubeka ngenxa yokufudumala kwehlabathi, uthuli oluthe kratya luya kususwa luphethe i-phosphorus kunye nezinye izakha-mzimba eziyimfuneko kwindalo yeentaba ezikude. Nangona kunjalo, ukuba izityalo azikwazi ukuziqhelanisa neemeko zemozulu ezintsha, izondlo ezisemhlabeni aziyi kunceda nto.
Izityalo zikhupha ioksijini ngefotosinthesisi, irhasi ngaphandle kwayo akukho namnye kuthi obeya kuba lapha namhlanje. Ngokusekwe koku, ndicinga ukuba kubaluleke kakhulu ukuba oorhulumente kunye nathi babakhusele. Into elula njengokutyala umthi inceda ekuphuculeni umgangatho womoya kwaye yenze imbonakalo yomhlaba ibonakale iluhlaza.
Ukuba akukho nto siyenzayo, kungekudala okanye kamva sinengxaki ezininzi.
