How habitat loss increases animal stress and suffering

One of the biggest drivers of this habitat loss is factory farming, as forests and grasslands are cleared to make way for crops and livestock. 

When wildlife habitat disappears, animals are forced into smaller, fragmented areas where they struggle to find food, water, and shelter. Infrastructure tied to industrial farming — like irrigation canals or fences used in wildlife farms — can also block migration routes or pose deadly hazards. This doesn’t just threaten their day-to-day survival. Destroyed habitats cause immense stress and suffering, disrupting their natural behaviours and, in turn, putting entire ecosystems at risk.

In this article, we look at habitat destruction examples and what we can do to prevent this from happening. 

What is habitat loss and why does it matter?

Habitat loss occurs when natural environments are destroyed or converted for human use, leaving animals without the space and basic resources they need to survive. 

This is different from habitat fragmentation, where large areas are broken into smaller, isolated patches, and habitat degradation, where pollution, invasive species, or overuse damage the quality of an environment without completely destroying it.

Habitat destruction can be catastrophic. Every species, from tiny microorganisms to huge animals, depends on healthy habitats. Over time, as these species lose their homes, they face hunger, stress, and displacement, which can lead to biodiversity loss and extinction.

The destruction of ecosystems, particularly forests and wetlands, also fuels climate change, as these environments play a key role in storing carbon and regulating the planet’s temperature.

How habitat loss causes animal stress

Factory farming is one of the leading causes of habitat loss and destruction, and its impacts on wildlife are far-reaching. Sudden changes to an animal’s environment place immense pressure on them, leading to stress that affects their health, behaviour, and long-term survival.

Disrupted behaviours and migration

When wildlife habitats are destroyed or fragmented, animals can no longer follow their natural patterns. Many wild species have evolved to migrate over long distances, but their typical paths can be cut off by farmland, roads, irrigation canals, or fences.

For example, maned wolves in South America rely on large, open landscapes to hunt and roam. As farmland expands, their ranges become restricted, forcing them closer to roads and human settlements. When these wild animals can’t hunt, they must kill and eat livestock to survive. Humans often kill these wolves in retaliation. 

Increased competition and crowding

With less space available, animals are pushed into overcrowded areas where they must fight for food, water, and shelter against other species and their own kind.

This is happening in Brazil, where bats are being forced into smaller forest patches due to agricultural expansion taking over their natural habitat. Crowding not only heightens conflict but also raises the risk of disease spreading quickly through populations.

Separation from family groups

When a wildlife habitat is broken up into isolated patches, animals can be separated from their family groups. This is especially devastating for animals that rely on close-knit connections.

Bornean elephants, for instance, need wide, connected forests to roam with their herds. When farmland and roads divide their habitat, family groups can split apart, leaving elephants stressed and vulnerable.

Restricted movement and loss of territory

Many species depend on vast areas of land to roam, hunt, and breed. When farmland destroys or blocks these territories, animals lose the freedom to move as they once did. 

Take jaguars. They regularly travel over six miles a day in search of food. They require large stretches of forest to stalk prey and maintain healthy populations. As their range is carved up for agricultural activities like cattle ranching and crop growing, they are pushed into smaller and smaller areas. This makes it tricky to maintain sufficient territory to feed themselves, and also increases the risk of conflict between individual animals.

Psychological and physical effects on wildlife

Animals are sentient beings. They are capable of experiencing both physical pain and psychological stress. When their homes are damaged or disappear, the harm they endure is not just physical. It’s deeply traumatic.

Land clearing causes substantial mortality, with deaths that are physically painful and psychologically distressing for the animals. In Australia, an average of 100 million native animals are displaced, injured, or killed every year due to land clearing, often to create space for beef production.

In Brazil, it’s a similar story. Large swaths of natural habitat are cleared with “controlled” burns that often spread out of hand, leading to deadly wildfires. In 2020 alone, roughly 17 million wild animals were killed in Pantanal due to human-caused wildfires.

Then, the animals that survive the initial destruction commonly suffer injuries, diseases, and extended stress as they navigate harsh new environments. They lack access to familiar food, shelter, or territory.

In countries like Brazil and Argentina, irrigation canals built to support animal feed crops have become deadly traps for wildlife. Animals such as anteaters and armadillos fall into the steep, unprotected canals and are often injured or killed trying to escape. Meanwhile, roads and motorways cut through fragmented landscapes, forcing animals to cross dangerous traffic routes. In Brazil alone, an estimated 400 million animals die each year in vehicle collisions — a staggering toll that reflects the widespread and often unseen consequences of habitat loss.

Protecting wildlife habitats worldwide is essential. It preserves biodiversity and prevents the widespread stress and suffering of millions of species caused by factory farming and other human endeavours. 

What can be done to reduce animal suffering?

Protecting and restoring wildlife habitats is one of the most effective ways to reduce the stress and suffering animals face. Human activity has put species at risk — but we can help reverse the damage, protect biodiversity, and give wildlife space to thrive again.

Here’s how we do it:

• Strengthening environmental laws
• Securing Indigenous land rights
• Supporting rewilding and habitat restoration
• Holding factory farming companies and funders accountable
• Transforming the global food system
• Ending the commercial exploitation of wild animals

And here’s how you can help:

• Eat fewer animal products.
• Speak up for animals and their habitats.
• Share what you learn.
• Support campaigns that drive change.
  

Even small actions can reduce animal suffering — and help build a world where wildlife lives freely and without fear.
