How many animals does being vegetarian save?

Posted on

An interesting analysis on the Counting Animals blog:

If we say that a vegetarian saves X animals per year, we should be able to also say that a semi-vegetarian saves X/2 animals per year and that a Meatless Mondayer saves X/7 animals per year. So, we will use the following formula to estimate the number of animals saved.

Number saved = Total number of animals killed
Population size ∗ ( 1.0 − V − S/2 − M/7 )

where V is the fraction of the population that is vegetarian, S is the fraction of the population that is not vegetarian but semi-vegetarian (defined as those who eat vegetarian at more than half their meals) and M is the fraction that is neither vegetarian nor semi-vegetarian but does eat vegetarian at least one day per week (such as a Meatless Mondayer). Using the results of the most recent pollcommissioned by the Vegetarian Resource Group, I will use V as 0.05, S as 0.16 andM as 0.04.

…and the results?

  • A vegetarian saves more than 30 land animals each year.
  • A vegetarian saves more than 225 fish each year.
  • A vegetarian saves more than 151 shellfish each year, so therefore:
  • A vegetarian saves more than 406 animals each year, at least an animal a day.
