The Scale
The numbers are not the argument. They are the evidence.
Twelve verified data points behind the case for plants. Sources at the foot of each card.
83B
Land animals killed every year
Most are raised in intensive systems; in the United States more than 99% of farmed animals live on factory farms.

1–2.8T
Sea animals killed annually
Most are not even counted in animal agriculture statistics. They die suffocating on decks, in nets, or in industrial tanks.

Water for 1 kg of beef
Animal products account for nearly a third of the water footprint of global agriculture. Most of beef's footprint is rain falling on pasture and feed crops.

Amazon deforestation from cattle
Cattle ranching is also the largest single driver of tropical forest loss worldwide.

Of farmland feeds livestock
Yet livestock provides only 18% of the world's calories and 37% of its protein. The math does not work — and never has.
Poore & Nemecek, 2018
32%
Of human-caused methane from livestock
Methane traps roughly 80× more heat than CO₂ over 20 years, so cutting it is one of the fastest ways to slow near-term warming.

73%
Of antimicrobials sold are used in farmed animals
Routine use in crowded sheds adds to antimicrobial resistance, which directly caused an estimated 1.27 million deaths in 2019.
Van Boeckel et al., Science 2019; Murray et al., Lancet 2022
86%
Of species at risk of extinction are threatened by agriculture
Farming — above all land used for livestock and feed — is the main driver of biodiversity loss on land; overfishing is the main driver at sea.
Chatham House / UNEP, 2021

Of grain fed to livestock yearly
About a third of the world's cereal harvest goes to animal feed. Meanwhile, about 730 million people faced hunger in 2023.

Of farmland could be returned to nature
A global shift to plant-based diets would free an area the size of the US, China, the EU and Australia combined — for forests, for wildlife, for water.

Lives saved per year by 2050
Modelling of a global shift to vegan diets estimated about eight million fewer deaths a year by 2050.
