30 000 years ago Bio-Land was a part of a much bigger land, which is currently in an unknown location. Bio-Land broke off it because of a big earthquake. Bio-Land floated over the seas for 5000 years until it bumbed into a chunk of land and stopped there. During hundreds of years Bio-Land has been fusing to that chunk of barren land slowly, and now the chunk of land has gone under it, so that only Bio-Land can be seen. Currently it's believed that Bio-Land has already been fused to the chunk of land for so long that it has actually come part of it. Bio-land is a still staying island now.
