NooOO.
 Notch needs to fix mob spawns to spawn according to geographical location D:
I like working a bit, lets say going on an adventure to the icy mountains just to tame a wolf. 
Cows only being found in flat grassy areas where trees are rare, same with chickens.
So on... 
 I can't stand seeing chickens, pigs, cows, and wolves all huddled together because the player is in a decent spawn location :((((((sssddssspop
