Animal agriculture is one of the biggest industries in the world with an worth estimated between 1.61 trillion to 3.3 trillion. It is the breeding, raising, and management of domesticated animals for human consumption. The farms can range from small to large and the majority are intensive. But to offer some perspective on the sheer size of this industry, they encompass 80% of agricultural land across the world yet only yield 18% of the world’s calorie consumption. This represents the inefficiency of animal consumption and the harm to food security. Animal agriculture is not simply a food system, but a reflection of humanity’s priorities – where efficiency and profit greatly outweigh ethics and sustainability.
The majority of the conditions in industrial farming are unbearable. Animals are subjected to confinement systems which essentially render them hostages. Many are physically mutilated for the purpose of efficiency. They are forced into overcrowded areas, activating chronic stress and leading to an increase in disease spread among them. The antibiotic overuse, while helpful, contributes to a worldwide issue of antibiotic resistance. These animals are treated as commodities and are practically disregarded as living beings. The cost of efficiency at a worldwide scale depends on suffering.
The industry is dominated by a handful of vast multinational corporations. They drive out smaller farmers or force them into debt contracts. Their true costs are masked in government support. While meat appears cheap, the real costs are externalized. While profit rises to the top, the consequences spread to the bottom.
The vast land use of animal agriculture has led to deforestation for grazing and feed crops. The loss of trees has led to an increase in carbon dioxide and has poisoned the very air we breathe. The concentration of cattle leads to a direct increase in greenhouse gasses that warm our earth and harm our climate. The industry is a huge consumer of the fresh water on earth and acts as a leading source of water pollution. The animal waste runoff leads to nutrient rich waters that cause harmful algae that kill aquatic life by creating dead zones in bodies of water. By mass converting natural habitats into farmlands for industry, we decimate the biodiversity of our ecosystems.
The “One Health” concept describes the interconnectedness cycles of human, animal and the planet’s health. The horrid conditions of how animals are treated and the effects of the industry directly impact human wellbeing. Diseases can jump from animal to humans and the overuse of antibiotics in livestock contributes to the antibiotic resistance that threatens public health. Environmental degradation caused by farming – polluted water, deforestation, and greenhouse gasses – bring further harm to communities. This creates a cycle in which the health of ecosystems, humans, and animals are inseparable.
This article isn’t attributing environmental destruction to your love of barbecue, but is instead meant to point out the injustice in the food industry and the need for systemic change. Simple solutions to help reduce the effects of the industry encompass, reducing meat consumption, curating plant forward diets, and advocating for better animal welfare standards. It is time to start fighting for environmental accountability. The key is intention, not abstinence.
Animal agriculture is a system that nourishes humanity while simultaneously straining the planet. The solutions aren’t about perfection, but instead about intentional action. Every choice we make – what we eat and what we support – affects the health of animals, ecosystems, and communities. By recognizing the interconnectedness of these systems, we can bring an end to the exploitation and bring rise to a food system that sustains life rather than harms it.
