Tiri panjodzi yekutsakatiswa!!!!!!

Aiwa vanhu vese vakabva vatanga kutaura nezvedambudziko rekusvibiswa kwetsvina nekupisa kwepasi kwakauraya mamiriyoni nekutamisa vamwe, asi unozviziva here kuti newewo hongu uri panjodzi yekutsakatika sezvakaita nyika yatigere, rega tikuudze chikonzero ,, Mushure mekunge masayendisiti ataura kuti masango nemagwenga Masisitimu anokosha epasirese anogona kuita "shanduko huru" pamusoro pezana ramakore rinotevera nekuda kwekushanduka kwemamiriro ekunze.

Chinjo dzakavamba kunyorwa kumaodzanyemba kwakadziva kumadokero kweUnited States, uko mwoto mikuru iri kuuya munzvimbo huru dzemasango.

Mumakore zana anotevera kana zana nehafu, shanduko idzi dzichasvika kumapani ane uswa (savanna) uye magwenga, zvichikanganisa masisitimu akakosha uye mhuka dzinotyisa nemiti muUnited States neEurope kunyanya, maererano neongororo yakabudiswa mumagazini "Sayenzi. ".

"Kana kushanduka kwemamiriro ekunze kukaramba kusingadzoreki, zvidyarwa zviri munyika yedu zvicharatidzika zvakasiyana chaizvo nezvazvinoita nhasi, izvo zvinounza njodzi huru mukusiyana kwenyika," akadaro Jonathan Overbeck, mukuru weSchool of Environment and Sustainability at.
