China suddenly announced today a complete ban on all storage and use of oxygen by it's citizens.
Citizens must now visit the official breathing stations twice a day to receive their allocation of the State developed O2 already referred to colloquially as the Fiart.
Underground cold storage of O2 is rumoured to have begun and organised rebel breathing is now being carried out in secret. Ex-pats are looking into ways to transfer O2 into the country using Twitter or peer-to-peer means.
Hedging markets have crashed resulting in artificial hedging synthetics blooming. Gas fees have hit an all time high.
It is rumoured that China will be banning light next if it's uncontrolled use continues to get out of hand
