The connection between the contents of our shopping carts and the destruction of remote tropical ecosystems is much more direct than most consumers realize. The latest economic and environmental analyses reveal alarming fact: A one-kilogram increase in annual per capita meat consumption is associated with an almost 2.1 trillion increase in the import of „embodied“ deforestation. This process is not just a matter of tree loss, but poses a direct threat to global biodiversity, with ruminant meat production carrying up to 340 times the risk of species extinction than cereal farming.

The invisible thread of global trade

Although forest area is increasing in many developed countries, such as the USA, Japan or European countries, global forest area decreased by 180 million hectares between 1990 and 2020. The reason is outsourcing of environmental burden. Richer countries with higher GDP per capita are shifting pressure on land use to tropical regions through international trade.

• Economic asymmetry: While a 1.% increase in GDP in exporting countries is associated with a slight decrease in deforestation, in importing countries the same GDP increase leads to a 0.88TP3T increase in imports of deforestation-related products.
• Embodied deforestation: This term refers to forest loss associated with the production of commodities that are subsequently traded and consumed far from their place of origin. Approximately one-quarter to one-third of global deforestation is directly linked to international exports.

Meat as the main engine of destruction

Agriculture, specifically the expansion of pastures and arable land for forage, is responsible for approximately 90 % of global deforestation. The main culprits are beef, soy (used mainly as feed) and palm oil.

1. Cattle: Cattle ranching and beef production are a dominant driver of deforestation, particularly in Latin America. It is estimated that up to 80% of deforestation in the Amazon is driven by meat production.
2. Soybeans and feed: Europe's overconsumption of meat creates huge demand for imported soy to feed livestock. The EU is the second largest importer of soy, linked to tropical deforestation, after China.
3. System inefficiency: Cattle pastures account for approximately 25 % of the world's ice-free land, yet meat and dairy products provide humanity with only 18 % of total calories.

Food and species extinction: The price on our plate

Agriculture and habitat conversion pose the greatest threat to global biodiversity. Scientists can now quantify these impacts using metrics LIFE (Land-cover change Impacts on Future Extinctions), which assesses the impact of land use on the extinction risk of approximately 30,000 vertebrate species.

Opportunity cost

This approach understands current food consumption as a lost opportunity to restore biodiversity. The differences between commodities are vast:

• Ruminant meat: It has a global median cost of species extinction of approximately 340 times higher than cereals and 100 times higher than plant proteins (legumes).
• Regional impact: Products from tropical and subtropical regions generally have a higher impact per kilogram due to the exceptional level of endemism and biodiversity in these regions.
• Luxury commodities: Coffee, cocoa and spices also have a high risk of extinction, although they are consumed in smaller quantities.

For countries in the Global North, such as the United Kingdom or Japan, it comes 95 % to 98 % impacts of their consumption on biodiversity from imported commodities. In this way, wealthy nations transfer the risk of species extinction to more biodiverse parts of the world.

Climatic and environmental contexts

In addition to habitat loss, animal production contributes to the environmental crisis in other ways:

• Greenhouse gas emissions: Livestock farming is responsible for approximately 15 % to 18 % global emissions. Tropical deforestation accounts for around one sixth (15 %) of the total carbon footprint of the average EU citizen's diet.
• Water and pollution: Producing one kilogram of beef requires up to 20,000 liters of water in some areas, while a kilogram of wheat requires a fraction of that amount. In addition, concentrated waste from animal husbandry contaminates air and water resources.
• Deforestation on peatlands: In Indonesia, up to a quarter of agriculture-related emissions are caused by the drainage of peatlands, mainly for palm oil.

The path to the solution: Less meat, more forest

Experts agree that drastically reducing the consumption of animal products, especially beef, is key to averting the extinction crisis and mitigating climate change.

• Power of substitutions: Replacement only 20 % of global beef consumption alternatives (e.g. microbial protein) by 2050 could reduce deforestation by half and methane emissions by 11 %.
• Changing your diet: Switching to a plant-based diet could reduce the need for agricultural land by 76 %. If the share of energy from ruminant meat in the US were reduced from 4 % to 1 %, the total cost of species extinction would fall by almost three-quarters.
• Policy measures: In 2023, the European Union adopted a regulation on deforestation-free products (Regulation (EU) 2023/1115), which requires traders to prove that products such as beef, soy or coffee do not come from deforested land.

Every decision we make at the meat counter has global consequences. The statistical correlation between a kilogram of meat and a 2 % increase in deforestation is not just an abstract number, but a direct reflection of the interconnectedness of our lifestyle with the fate of tropical forests and thousands of endangered species. Reducing the demand for meat in rich countries is not just a matter of personal health, but a necessary step to preserve the planet's biodiversity for future generations. JRi&CO2AI
