Minecraft - Wasteland with this Mod (1.1)

The Wasteland Mod changes the Minecraft world into a post apocalyptic wasteland. The sky has become dark, the grass died away, forest fires became rampant, and the rivers have run dry. It is your goal to survive in this rough world.
Features:
Minecraft Apocalypse
No more grass:
The apocalypse has caused all of the grass in Minecraft to die off. Tall grass have turned into dead shrubs. With a lack of vegetation, mobs such as cows and chickens have gone extinct.

Changes to trees:
Most of the trees in Minecraft have died out. The only trees left are large, ancient trees that have no leaves and those found in sanctuaries.

No pumpkins, reeds, or flowers:
These fragile plants have long died out in the desert.

No oceans:
Oceans have dried up. The only water available are small springs found in Oasis.

Changed Sky Color:
The dry environment of the desert has changed the sky into a darker, red color.

Sanctuaries:
Sanctuaries are small 4×4 squares of grass with a tree, water, and some randomised tall grass and flowers. These will help you survive.

Ruins:
If you are lucky you will come across ruined houses. They contain a chest with supplies that will help you survive. They are also good sources of wood.

Modified Dungeons:
Dungeons are now more like fall out shelters. There chests are full of items such as saplings, buckets of water, and planks. There are also naturally occuring beds inside next to the spawner.
