The statement that is not true of livestock production is:
C. Globally, nearly all livestock waste is returned to the earth as fertilizer.
This statement is not accurate. While some livestock waste is used as fertilizer, it is not the case that nearly all livestock waste is returned to the earth in this manner. Livestock waste, such as manure, can be a valuable source of nutrients for crops when properly managed, but in many cases, especially in large-scale industrial livestock operations, waste disposal can be a significant environmental concern. Improper handling of livestock waste can lead to water pollution, including contamination of rivers and groundwater. Additionally, some livestock waste may be used in other ways, such as for energy production or may not be effectively managed, contributing to environmental issues. Therefore, it cannot be said that nearly all livestock waste is used as fertilizer.
