Giant sinkhole with a forest inside found in China - "Species unknown to science could be hiding in this gaping hole."
In the 80s a Swedish beekeeper created a local currency to see his little village through cash-strapped times. One Clover (the name of the currency) is worth the same as (and exchangeable for) a 0.7kg jar of honey. Honey stores forever and its value fluctuates extremely little. There is currently around 2500 Clovers in circulation, quite enough for the village to run a functional local economy without involving the government.
