In his book "Eating Animals," Jonathan Safran Foer highlights the staggering amount of waste generated by farmed animals in the United States. He points out that this waste is 130 times greater than that produced by the human population. This statistic underscores the significant environmental impact of animal farming, particularly in terms of pollution and resource management.

Foer's work encourages readers to consider the implications of animal agriculture, not only regarding animal welfare but also its broader effects on the environment. The vast amount of waste contributes to pollution issues, affecting air and water quality, leading to significant ecological concerns.
