Muslim Majority

I predict that planet earth will be Majority Muslim in this century. Already, we see many countries that were once Christian have growing Muslim populations. For example, in russia there will be a Muslim majority by midcentury. The Christian Orthodox church is now in demographic decline because their members have less than two children per couple (1.3) versus Muslims have about 8 children per couple. I predict that russia will soon become a sharia law Muslim run nation.
