When you put the continents next to each other (on a map, of course) in a certain way, they put together almost perfectly. To add to that, there are fossils of the same land species on two different continents, suggesting that they used to be able to cross back and forth between the two land masses. This would make the most sense if the two continents were once part of the same continent.
Well one possible reason could be because it could ruin the land. When land focuses on the mass production of a certain crop, the land loses essential nutrients and will deteriorate overtime.
