To Meet the Sustainable Development Goals, Prioritize Animal Welfare

This month sees United Nations member states gather at the 80th United Nations General Assembly in New York to debate the most important global issues.

Ten years ago, the assembly agreed on a set of 17 Sustainable Development Goals (SDGs) to end poverty, protect the planet, and ensure peace and prosperity for all by 2030.

One key accelerator that has been continuously overlooked in the SDGs is animal welfare. Nowhere is this more evident than in how we treat farmed animals and manage our food systems. Industrial systems, where the majority of the around 85 billion land animals farmed for food each year are raised, drive climate change, hunger, pollution, and inequality. Yet, higher-welfare, sustainable practices show how respecting animals can help deliver progress across the SDGs. Unless we take animal welfare seriously, we’ll fall short of achieving sustainability. The systems in which we farm animals are an illustration of this.

At the United Nations Environment Assembly in 2022, member states explicitly acknowledged that “animal welfare can contribute to achieving the Sustainable Development Goals.” So the mandate is there, but what does this actually mean in practice when it comes to specific goals? How does improving animal welfare drive progress on sustainable development, better people’s lives, and support the environment around us?

Farm Animal Welfare and Climate Change

One of the biggest threats we face is addressed in SDG 13: "Combating Climate Change," a significant contributor to which is the industrial exploitation of animals for food. The Food and Agriculture Organization estimates that animal agriculture contributes 14.5% of human-caused emissions.

Higher animal welfare farming systems offer solutions. Agroecological approaches where animals are integrated into local environments that can provide them with food (i.e. grass), and manage their waste in sustainable, regenerative ways, have greater capacities for carbon sequestration potential compared with industrial animal farming. They are also more resilient to climate change and disasters, thereby supporting mitigation and adaptation.

Without changing our relationship with animals, we have no hope of reaching these ambitious SDGs.

We need to introduce policy solutions that enhance such sustainable agriculture practices, alongside those encouraging the reduction of overconsumption of animal-sourced foods.

Our Global Food System Fuels Food Insecurity

Another victim of our intensive animal agricultural system is global food security. There is a misconception that we need to upscale production of animal-sourced foods to feed a growing global population. But this is a fallacy. Evidence from recent decades shows that increased production serves overconsumption. In fact, SDG 2: "Zero Hunger" is out of reach if we continue to squander such vast quantities of human-edible resources on inhumanely farmed animals. A recent study found that fewer than half the calories grown on farms now reach our plates—calories that could be eaten directly by humans. With the World Health Organization (WHO) citing that around 733 million people faced hunger in 2023, feeding crops to humans, instead of animals, should be prioritized if we are serious about achieving food security.

Animal and Human Health and Well-Being Are Intrinsically Connected

Our exploitation of animals is also a source of air, soil, and water pollution in many regions, addressed in SDG 6: "Clean Water and Sanitation." Overreliance on fertilizers and pesticides in industrial agriculture systems can cause soil and water pollution. Furthermore, air pollutants such as faecal dust, ammonia, and hydrogen sulphide are consequences of intensive systems, all posing human health risks. This comes in contradiction to SDG 3: "Ensure Healthy Lives and Promote Well-Being for All at All Ages."

There are other health impacts to the way we treat animals. Antimicrobial resistance in humans has been named by the WHO as one of the top global public health and development threats, accelerated by the routine use of antimicrobials in intensive animal farming to offset the risks of concentrating excessive numbers in crowded conditions, or to speed up growth for greater profit.

Animal Exploitation Is Linked to Biodiversity Loss and Nature Depletion

SDG 15 aims to protect life on land, yet globally monitored population sizes of mammals, fish, birds, reptiles, and amphibians have declined an average of 68% between 1970 and 2016. These drastic reductions reveal a broken relationship between humans and the natural world, and show that far too little action has been taken to date.

Agriculture uses half of the world’s habitable land, with animal farming accounting for 77% of globally available farming land. Land-use change, primarily related to animal agriculture, is a huge contributor to biodiversity loss. To prevent the alarming loss of wildlife, habitat destruction, and pollution, we need to protect animals who play critical roles as pollinators, nutrient recyclers, and environmental custodians. We need bees for our food system, forest-dwelling elephants for carbon storage, and beavers building dams to restore wetlands, to name a few examples.

Our Global Food System Exacerbates Poverty and Inequality

Ultimately, a key driver of the SDGs is the ambitious first goal—to end poverty. But by exploiting animals for food, we are heightening it. The overindustrialization of animal agriculture is lining the pockets of a few global giants, while small-scale farmers are being pushed out. Higher-welfare farming systems can have positive impacts on the livelihoods of smallholders, for many of whom animals are their primary productive asset, creating employment opportunities in the rural economy and reducing poverty. Furthermore, for the many communities who rely on working and other animals for their livelihoods, improving how their animals are cared for will help keep them from the cycle of poverty.

A missing piece in the SDG puzzle

The SDGs provide the blueprint for “peace and prosperity for people and the planet, now and into the future.” This may seem like an insurmountable feat. And it is insurmountable if we carry on as before. What is clear is that, without changing our relationship with animals, we have no hope of reaching these ambitious SDGs.

The way we raise, trade, and consume farmed animals is an example of the nexus between animal welfare and hunger, health, climate change, and poverty. But this is an example. Whether wild, farmed, or companion, animal welfare is a lever for sustainable development. Being kind to animals is not just "a nice to have" but a "need to have" if we want to have any hope of a more prosperous future, for the planet and all who live in it.
