Meat & Plant-Based: Pork Meals vs Water Used (Bathtubs)
See how your meat & plant-based habit scales when comparing pork meals to water used (bathtubs). What's the true cost of your meal? Calculate the resources used for meat, or see how many animals, land, and water you save by eating plant-based.
Size My Meat & Plant-Based
Your Habit Scale
| Time Period | Equivalent in Water Used (Bathtubs) |
|---|---|
| 1 Year | 1,468.2 bathtubs |
| 5 Years | 7,341.2 bathtubs |
| 25 Years | 36,705.9 bathtubs |
How It's Calculated
Calculations are based on the resources used for one 200g (≈ 7 oz) meal of Pork Meals.
- Your input: 2 Pork Meals per week.
- This equals 104 meals per year.
- Each meal requires 2,400 Litres (≈ 634.0 US gallons) of water.
- The total water saved is divided by 170 Litres (≈ 44.9 US gallons) (the volume of one bathtub).

Why It's Important
Your meat consumption uses approximately 1,468.2 water (bathtubs) over a year. This highlights the collective environmental footprint of this dietary choice.
Why is this important? Each meal choice has an impact on the planet. Visualizing the resources in terms of water used, land used, or CO₂ emissions produced connects our personal habits to major global issues. It's a powerful reminder that our plates have a profound impact on environmental sustainability and climate change.

The Science Behind It
Your dietary choices have a significant impact on the planet. This calculator helps visualize the environmental and ethical impact of consuming beef, pork, and chicken by showing the resources saved when these meals are replaced with plant-based alternatives. The data is based on life-cycle assessments of food production.
1. Animal Lives Spared
The "Animals Saved" metric is calculated based on the average retail meat yield per animal. For example, one cow produces approximately 2,140 individual 100g meals. By choosing a plant-based option, you directly reduce the demand that drives these numbers.
2. Water Footprint
Agriculture is a major consumer of global freshwater resources, and animal agriculture is particularly thirsty. The water footprint includes water for drinking, cleaning, and, most significantly, irrigating the crops grown to feed the animals. A single 100g beef meal has a water footprint of over 1,500 liters.
3. Land Use
Livestock farming is the world's largest user of land resources, with grazing and feed crop production occupying a vast percentage of the Earth's habitable land. This is a leading cause of deforestation and biodiversity loss. Beef production is especially land-intensive, requiring over 32 square meters per 100g meal.
4. Greenhouse Gas Emissions (CO₂-eq)
The food system is responsible for about a quarter of all human-caused greenhouse gas emissions. Ruminant animals like cattle produce large amounts of methane, a potent greenhouse gas, through digestion. The entire supply chain, from feed production to processing, contributes to the carbon footprint of meat.
