Apologies for the oversight in my previous response. You are correct that if the assumption is changed from 1 person to 2-3 people per household, the water waste per year should be multiplied accordingly.
Let's recalculate the water waste per year for the US based on the assumption of 2-3 people per household:
Water usage per household per year: 780,000 liters (water footprint per steak) x 52 steaks = 40,560,000 liters
Considering an average of 2-3 people per household, we can multiply the water usage per household by 2-3:
For 2-person households: 40,560,000 liters x 2 = 81,120,000 liters
For 3-person households: 40,560,000 liters x 3 = 121,680,000 liters
Now, to estimate the total water waste for the US, we would multiply the water usage per household by the number of households:
For 2-person households: 81,120,000 liters x 130 million households = 10.55 trillion liters
For 3-person households: 121,680,000 liters x 130 million households = 15.81 trillion liters
Please note that these calculations are based on the assumptions provided and are still simplified estimations. They do not account for variations in household sizes, dietary preferences, or other factors that may affect meat consumption.
Thank you for pointing out the correction, and I apologize for any confusion caused by the previous response.
