Man-made and Natural Resources
Krypton is an element, and all elements are the result of nuclear fission, nuclear fusion or radioactive decay. Krypton is one of the byproducts of the nuclear fission of Uranium and Plutonium, either from atomic bombs or nuclear reactors. Since Krypton is not one of the results of a natural radioactive decay chain, the only other possible source of Krypton is from nuclear fusion, and the only source of fusion powerful enough to produce it would be a supernova.
No "NATURAL" calamities are man made.
