Question

as countries change during a demographic transition, there is often a growing demand for meat in human diets. it takes an estimated 1,750 liters of water to produce 113 grams of beef. the average person in a more developed country consumes 85 grams of beef per day. (i) calculate the amount of water needed, in liters per year, to produce the beef consumed by one person in a more developed country.

Answer 1

480,496 liters

Explanation:

To calculate the amount of water needed to produce the beef consumed by one person in a more developed country per year, we need to first determine the amount of beef consumed per year and then multiply it by the water required to produce a given amount of beef.

The average person in a more developed country consumes 85 grams of beef per day. To find the annual consumption, we multiply this value by the number of days in a year:

Annual beef consumption = Daily beef consumption * Number of days in a year

Annual beef consumption = 85 grams/day * 365 days/year

Annual beef consumption = 31,025 grams/year

Now, we need to convert the beef consumption from grams to liters of water. It takes 1,750 liters of water to produce 113 grams of beef:

Water required per gram of beef = 1,750 liters / 113 grams

To calculate the total water needed per year, we multiply the water required per gram of beef by the annual beef consumption:

Water needed per year = Water required per gram of beef * Annual beef consumption

Water needed per year = (1,750 liters / 113 grams) * 31,025 grams/year

Calculating this value:

Water needed per year ≈ 480,496 liters/year
