Why is my survival world so laggy?

Why is my survival world so laggy? A possible problem is that there are too many blocks being rendered at once, making Minecraft lag. Try checking if all your machines are off and the amount of mobs on your screen (100 or more would cause a problem). There could be too many things happening at once.
