Pfupisa nyaya yacho:  Kufa Kukuru, uko kwakarova Pasi makore ane mamirioni 252 apfuura, kwakaparadza zvinopfuura 96 muzana zvezvisikwa zvenyika. Uye nepo kuputika kukuru kwemakomo kunowanzonzi ndiko kwakaparira chiitiko chacho, nzvero yakawana kuti marudzi mazhinjisa ari papasi pakupedzisira akaurawa apo makungwa akava ane acid zvikuru. Zvikurukuru, vanotaura kuti kuputika kwemakomo anoputika kwakabudisa uwandu hukuru hwecarbon dioxide iyo yakaiswa mumakungwa ndokuchinja makemikoro awo. Kufa Kukuru, uko kwakarova Pasi makore ane mamiriyoni 252 akapfuura, kwakaparadza zvisikwa zvinopfuura 96% zvenyika. Uye nepo kuputika kukuru kwemakomo kazhinji kazhinji kuchipomerwa mhaka yokubudisa chinoitika chacho, nzvero yakawana kuti marudzi mazhinjisa epasi pakupedzisira akaurawa apo makungwa akava ane acidic zvikuru. Kudzidza uku, kwakatungamirirwa neYunivhesiti yeEdinburgh, ndiko kwokutanga kuratidza kuti mvura yemumakungwa ine asidhi yakawanda ndiyo inokonzera izvi. Uye vatsvakurudzi vakati uwandu hwecarbon yakawedzerwa mumhepo yakapoteredza pasi kuti itange kutsakatika kwacho kwakawanda 'zvimwe hwakanga hukuru zvikuru kupfuura zvicherwa zvamazuva ano zvezvinhu zvinopisa.' Kufa Kukuru, kunozivikanwawo sokutsakatika kwePermian-Triassic Boundary, kwakaitika mumakore 60 000, uye kuoma kwemakungwa kwakatora makore anenge 10 000. Panguva iyi, nyika yose yakanga yakafukidzwa nekondinendi imwe chete yainzi Pangaea. Nyika huru iyi yakasika mamiriro akaoma zvikuru uye pakazosvika nguva yePermian yekupedzisira, tembiricha dzakanga dzakakwirira zvikuru. Kupisa kwakanyanyisa uku kwakanga kwatotyisidzira marudzi mazhinji epanyika neomumvura, asi izvi zvakawedzerwa apo kuputika kukuru kwemakomo kwakavamba kuitika. Huwandu hukuru hwevhu rinoputika rebasalt rakafukidza nharaunda inenge yakapetwa kanomwe kukura kweFrance, yakatsanangura kudaro Natural History Museum, uye sulphur dioxide inobva mukuputika uku yakaparira mvura yeacid yakafanana nevhiniga kufukidza Pasi. Munguva yokufa kukuru, nyika huru inonzi Pangaea yakafukidza Pasi. Nyika iyi (inoratidzwa pamufananidzo) yakaita kuti pave nemhepo inopisa uye yakaoma. Kufa Kukuru, kunozivikanwawo sokutsakatika kwePermian-Triassic Boundary, kwakaitika mamiriyoni 252...
Nyanzvi dzezvokuchera matongo dzakadzidza matombo muUnited Arab Emirates ayo angave aiva pasi pegungwa panguva yokufa kukuru makore 252 miriyoni apfuura. Kubva pane izvi vaigona kugadzira muenzaniso wemamiriro okunze kuti vanyore kuparara kwevanhu vakawanda. Vanodavira kuti kuputika kwemakomo kunobudisa carbon dioxide mumakungwa. Uye kukwira kweacidity 'kwakarova kokupedzisira' gadziriro yezvinhu zvipenyu yakanga isingachagadzirisiki.
