One effect of our overgrazing of the natural range lands is;

• Increased biodiversity because of the increase in plants cattle will not eat, such as mesquite, sagebrush, and cactus, as well as the insects and mammals these plants attract.

• Decreased solar power because soil is compacted and can no longer support power cells.

• Inversion of the human population pyramid as less vegetation is available and ranchers must sell their cattle because of the lack of rangeland available to them.

• Soil erosion, because cattle damage the grass roots and the grass can no longer regrow.

• Increased soil porosity, because cattle are not present to compact the land they occupy.
