"The enslavement of other animals necessitated invasion and large scale warfare due to the need of fresh pastures and water, and their oppression enabled the widespread warfare due to the use of other animals was rations, laborers, and weapons of war. For thousands of years, violent patriarchal societies led by warmongering men continually seeking greater wealth and power did enormous harm to the foundation of human societies and to human relationships with other animals. Millions of humans and countless other animals suffered enslavement, torture and death—and their fates were deeply intertwined."
