This is a book about the history of grasslands.
This is a video that briefly explains where and what grasslands are.
About 40% of natural grasslands worldwide have potential to support increased livestock grazing. This translates to a potential increase of 5% in milk production and 4% in meat production.
The lack of water and the changing patterns of rain will either deprive the grasslands of water or it could give the grasslands too much water.
Population Growth affects the grasslands in a negative way. As the population grows grasslands around the world are in danger from the expansion of housing, farming and this eliminates the food for herbivores and other plant eating animals.
