For Planet
Animal agriculture is a major driver of deforestation, water scarcity, and greenhouse gas emissions. Shifting towards plant-based systems is essential to protect our forests, conserve resources, and combat climate change. A better future for the planet begins on our plates.
Earth’s Cost
Factory farming is destroying our planet’s balance. Every plate of meat comes at a devastating cost to the Earth.
Key Facts:
- Millions of acres of forests destroyed for grazing land and animal feed crops.
- Thousands of liters of water needed to produce just 1 kg of meat.
- Massive greenhouse gas emissions (methane, nitrous oxide) accelerating climate change.
- Overuse of land leading to soil erosion and desertification.
- Pollution of rivers, lakes, and groundwater from animal waste and chemicals.
- Loss of biodiversity due to habitat destruction.
- Contribution to ocean dead zones from agricultural runoff.
The Planet in Crisis.
Every year, approximately 92 billion land animals are slaughtered to meet the global demand for meat, dairy, and eggs — and an estimated 99% of these animals are confined in factory farms, where they endure highly intensive and stressful conditions. These industrial systems prioritize productivity and profit at the expense of animal welfare and environmental sustainability.
Animal agriculture has become one of the most ecologically damaging industries on the planet. It is responsible for around 14.5% of global greenhouse gas emissions — largely methane and nitrous oxide, which are significantly more potent than carbon dioxide in terms of warming potential. In addition, the sector consumes vast amounts of freshwater and arable land.
The environmental impact does not stop at emissions and land use. According to the United Nations, animal agriculture is a major driver of biodiversity loss, land degradation, and water contamination due to manure runoff, excessive antibiotic use, and deforestation—especially in regions like the Amazon, where cattle ranching accounts for roughly 80% of forest clearing. These processes disrupt ecosystems, threaten species survival, and compromise the resilience of natural habitats.
There are now over seven billion people on Earth — twice as many as just 50 years ago. Our planet’s resources are already under immense strain, and with the global population projected to reach 10 billion in the next 50 years, the pressure is only increasing. The question is: So where are all our resources going?
Depleting Resources
Animal agriculture consumes vast amounts of land, water, and fossil fuels, placing immense strain on the planet’s finite resources.
Polluting the Planet
From toxic manure runoff to methane emissions, industrial animal farming contaminates our air, water, and soil.
Facts
GHGs
Industrial animal agriculture produces more greenhouse gases than the entire global transportation sector combined.
15,000 liters
of water are required to produce just one kilogram of beef — a stark example of how animal agriculture consumes one-third of the world’s freshwater.
60%
of global biodiversity loss is linked to food production — with animal agriculture being the leading driver.
75%
of global agricultural land could be freed if the world adopted plant-based diets — unlocking an area the size of the United States, China, and the European Union combined.
The Problem
Factory Farming Environmental Impact
Factory farming intensifies climate change, releasing vast volumes of greenhouse gases.
It’s now clear that human-driven climate change is real and poses a serious threat to our planet. To avoid surpassing a 2ºC rise in global temperatures, developed nations must cut greenhouse gas emissions by at least 80% by 2050. Factory farming is a major contributor to the climate change challenge, releasing vast volumes of greenhouse gases.
A wide variety of sources of carbon dioxide
Factory farming emits greenhouse gases at every stage of its supply chain. Clearing forests to grow animal feed or raise livestock not only eliminates crucial carbon sinks but also releases stored carbon from soil and vegetation into the atmosphere.
An energy-hungry industry
An energy-intensive industry, factory farming consumes vast amounts of energy — mainly to grow animal feed, which accounts for around 75% of total usage. The rest is used for heating, lighting, and ventilation.
Beyond CO₂
Carbon dioxide isn’t the only concern — livestock farming also generates large amounts of methane and nitrous oxide, which are far more potent greenhouse gases. It’s responsible for 37% of global methane and 65% of nitrous oxide emissions, mainly from manure and fertilizer use.
Climate change is already disrupting farming — and the risks are rising.
Rising temperatures strain water-scarce regions, hinder crop growth, and make raising animals harder. Climate change also fuels pests, diseases, heat stress, and soil erosion, threatening long-term food security.
Factory farming endangers the natural world, threatening the survival of many animals and plants.
Healthy ecosystems are essential to human survival — sustaining our food supply, water sources, and atmosphere. Yet, these life-supporting systems are collapsing, in part due to the widespread impacts of factory farming, which accelerates biodiversity loss and ecosystem degradation.
Toxic outputs
Factory farming generates toxic pollution that fragments and destroys natural habitats, harming wildlife. Waste often leaks into waterways, creating "dead zones" where few species survive. Nitrogen emissions, like ammonia, also cause water acidification and damage the ozone layer.
Land Expansion and Biodiversity Loss
The destruction of natural habitats drives biodiversity loss worldwide. About one-third of global croplands grow animal feed, pushing agriculture into critical ecosystems in Latin America and sub-Saharan Africa. Between 1980 and 2000, new farmland in developing countries expanded to over 25 times the size of the UK, with more than 10% replacing tropical forests. This growth is mainly due to intensive farming, not small-scale farms. Similar pressures in Europe are also causing declines in plant and animal species.
Impact of Factory Farming on Climate and Ecosystems
Factory farming generates 14.5% of global greenhouse gas emissions—more than the entire transport sector. These emissions accelerate climate change, making many habitats less livable. The Convention on Biological Diversity warns that climate change disrupts plant growth by spreading pests and diseases, increasing heat stress, altering rainfall, and causing soil erosion through stronger winds.
Factory farming harms the environment by releasing various harmful toxins that contaminate natural ecosystems.
Factory farms, where hundreds or even thousands of animals are densely packed, generate various pollution issues that harm natural habitats and the wildlife within them. In 2006, the United Nations’ Food and Agriculture Organization (FAO) called livestock farming “one of the most significant contributors to today’s most serious environmental problems.”
Lots of animals equals lots of feed
Factory farming relies heavily on grain and protein-rich soy to rapidly fatten animals — a method far less efficient than traditional grazing. These crops often require large amounts of pesticides and chemical fertilizers, much of which ends up polluting the environment rather than aiding growth.
The Hidden Dangers of Agricultural Runoff
Excess nitrogen and phosphorus from factory farms often seep into water systems, harming aquatic life and creating large "dead zones" where few species can survive. Some nitrogen also becomes ammonia gas, which contributes to water acidification and ozone depletion. These pollutants can even threaten human health by contaminating our water supplies.
A Cocktail of Contaminants
Factory farms don’t just release excess nitrogen and phosphorus — they also generate harmful pollutants like E. coli, heavy metals, and pesticides, threatening the health of humans, animals, and ecosystems alike.
Factory farming is highly inefficient — it consumes immense resources while yielding comparatively low amounts of usable food energy.
Intensive animal farming systems consume enormous quantities of water, grain, and energy to produce meat, milk, and eggs. Unlike traditional methods that efficiently transform grass and agricultural by-products into food, factory farming relies on resource-intensive feed and delivers a relatively low return in terms of usable food energy. This imbalance highlights a critical inefficiency at the heart of industrial livestock production.
Inefficient Protein Conversion
Factory-farmed animals consume large amounts of feed, but much of this input is lost as energy for movement, heat, and metabolism. Studies show that producing just one kilogram of meat can require several kilograms of feed, making the system inefficient for protein production.
Heavy Demands on Natural Resources
Factory farming consumes vast amounts of land, water, and energy. Livestock production uses about 23% of agricultural water—around 1,150 liters per person daily. It also depends on energy-intensive fertilizers and pesticides, wasting valuable nutrients like nitrogen and phosphorus that could be better used to grow more food efficiently.
Peak Resource Limits
The term "peak" refers to the point when supplies of crucial non-renewable resources like oil and phosphorus—both vital for factory farming—reach their maximum and then start to decline. Although the exact timing is uncertain, eventually these materials will become scarce. Since they are concentrated in a few countries, this scarcity poses significant geopolitical risks for nations dependent on imports.
