No, what would happen would be much worse than that. Most, or all, of humanity would die. If it happened suddenly, or even over a few years, an ocean would form that would swallow up Europe, Asia, and North America. Latitudes toward the equator would become unlivable, because there would be little oxygen. A new continent would form between North America and Asia. Day and night would start out lasting several days and once the planet stopped completely spinning, a day would be a year. Much of the remaining land areas would become dry as air currents (wind) would become nonexistent. It's not a good scenario at all.
