Does soy really destroy forests?
When we talk about deforestation, soy often comes up in the conversation. It is accused of razing tropical forests and being responsible for the disappearance of entire ecosystems, particularly in Brazil and the Amazon.
But are tofu or soy milk really the things destroying the forest?
The reality is much more complex. Soy is currently one of the most produced crops in the world, with approximately 350 million tons each year, grown on 129 million hectares. Yet, what many people don't know is that we only consume a tiny fraction of it directly.
So, if it’s not us eating it… who is? And above all, what is the real link between soy-driven deforestation and our daily lives?
Why is soy a problem?
One might think that plant-based steaks or soy yogurts are fueling deforestation. In reality, that is not the case.
Soy, primarily for animal feed
Approximately 87% of the soy produced globally is used to feed livestock: cattle, pigs, poultry, as well as dairy cows and laying hens.
Direct human consumption accounts for barely 7% of global production.
The rest? A small portion is used to produce oil and biofuels (about 5.6%).
In other words: if you eat meat, cheese, or eggs, you are indirectly consuming soy even if you don't see it on your plate!
Massive production that nibbles away at ecosystems
To meet global demand, the surface area dedicated to soy cultivation continues to expand.
Forests replaced by fields
In South America, soy expansion is one of the major drivers of deforestation. This obviously includes the Amazon, but also other less well-known regions like the Cerrado or the Gran Chaco.
These ecosystems harbor exceptional biodiversity. Yet, they are progressively being transformed into monocultures primarily intended to feed livestock exported all over the world.
Although certain measures such as moratoriums have slowed deforestation in some areas, the problem has not stopped: it has sometimes simply shifted.
The hidden footprint of our food
This is where things get interesting.
Eating meat means "eating" soy
Producing animal-based foods requires enormous quantities of soy:
- 12 m2 per 1kg of beef
- 15 m2 per 1kg of pork
- 70 m² per 1kg of poultry
- 30 m² for dairy products
- 30 m² for eggs

These figures show one simple thing: soy-driven deforestation is closely linked to our consumption of animal products.
The more the demand for meat and dairy products grows, the more soy production follows.
Being vegan: a direct lever against deforestation
Stop supporting intensive farming
Adopting a vegan diet means choosing not to consume products derived from animals: no meat, fish, dairy, or eggs.
Concretely, this also means no longer supporting the intensive farming system, which is the main engine of the massive production of soy.
If approximately 87% of global soy is used to feed animals destined for consumption, then reducing (or eliminating) the consumption of animal products directly decreases the demand for soy for livestock.
Less demand → less pressure to convert forests into agricultural land.
A systemic impact
Of course, change does not rely solely on individuals. Governments, multinational corporations, and import chains have a major responsibility.
But on a personal scale, choosing a plant-based diet is one of the most effective ways to reduce your impact on soy-related deforestation.
That doesn't mean everyone has to become vegan overnight! Even reducing your meat consumption has an effect. But it is important to understand that the link between livestock, soy, and deforestation is direct.
So, does soy really destroy forests?
Yes and no!
Soy itself is not the "villain" of the story. The problem is the gigantic quantity produced to support a food model based on high meat consumption and animal products.
Soy-driven deforestation is therefore not just an agricultural issue; it’s a system issue!
