One of the absolute coolest inventions of modern man is the ability to freeze things for future use. In fact it was all over the news this past week or two that a "prehistoric" flower was grown in a laboratory after it's seeds were found in a frozen state for supposedly thousands of years. Growing things is not a hit or miss science any more. Mankind's knowledge, as confirmed by biblical prophecy, has truly increased.
Hence the creation of the gigantic frozen seed vault in Norway in 2008, (not too far from the north pole) which contains umpteen number of food crop seeds. In case of global catastrophe mankind would be able to restart it's food chain by replanting seeds for its main food sources.
Some of the funding for this seed vault has been paid for by Bill and Melinda Gates Foundation. How intriguing.
