Bez n\u011bj by na\u0161e Zem\u011b byla mnohem chladn\u011bj\u0161\u00ed.

Ten z\u00a0naprost\u00e9 v\u011bt\u0161iny vznik\u00e1 d\u00edky procesu fotosynt\u00e9zy, kter\u00fd se bez slune\u010dn\u00edho sv\u011btla neobejde.

Bez Slunce by jeho obsah brzy velmi poklesl, k\u00a0\u010demu\u017e by samoz\u0159ejm\u011b pomohla tak\u00e9 zima.\u00a0Lid\u00e9 by samoz\u0159ejm\u011b mohli vz\u00edt n\u011bjak\u00e9 rostliny sebou a pou\u017e\u00edt um\u011bl\u00e9 osv\u011btlen\u00ed, pravd\u011bpodobn\u011b by to v\u0161ak ani zdaleka nesta\u010dilo.\u00a0\u00a0V\u00a0neposledn\u00ed \u0159ad\u011b je tu fakt, \u017ee pr\u00e1v\u011b Slunce n\u00e1s udr\u017euje na orbit\u011b.
