[email protected]11/3/2017Okay so I've only had this game for a few days and I've been trying to sucessfully breed either a dodo or a dilo and no matter what I seem to do I always loose it after hatching. After loosing 4 dodos I build a structure with space for babies to move around in safely without worry of a dinosaur killing it and I railed off section for fires in a corner I could set the egg next
Get PriceSF 6 Sulfr hexafluoride (or Sulphur Hexafluoride) had been the standard gas used inside high voltage electrical equipment as an insulating and arc-quenching medium. However, SF 6 Sulfr hexafluoride is also listed as an extremely potent greenhouse gas according to the Kyoto protocol, with 23,500 times the comparative Global Warming Potential of CO 2 and a lifetime of 3,200 years in the atmosphere.
