Hemispheres

Minecraft has four directions, just like real life, Never Eat Soggy Waffles.

Now I propose from spawn, as you move out  south or north you go into colder and more temperate biomes, but you start off in tropical, subtropical, or arid environments the closer to the spawn "equator" you are.

I also think that certain plants and animals should spawn in certain sections of your world.  For example, pandas and bamboo spawn in jungles east of spawn, but ocelots and parrots spawn in jungles west of spawn. Polar bears and foxes spawn in cold biomes north of spawn, and well, we don't have any southern pole animals in Minecraft, but I'm assuming we might have things like penguins in the future so lets use those as an example for southern cold biome animals.

This started when I was building an African themed build and cleared out all the cactus, so yes please make cactus spawn west of spawn
