* No central database: There's no organization tracking how many people participate in Meatless Monday globally, and even if there were, it would be hard to measure individual dietary changes.
* Varying meat consumption: People eat different amounts of meat, and "meatless" can mean different things (no red meat, no poultry, no animal products at all).
* Global meat production: The number of animals raised for meat is vast and changes constantly.
However, we can make some educated guesses:
* Estimated impact: The Meatless Monday movement estimates that a global shift to one meatless day per week could reduce greenhouse gas emissions by 5% and save billions of animals per year.
* Individual impact: If you were to reduce your meat consumption by even one day a week, you would be making a difference in terms of animal welfare, environmental impact, and personal health.
The key takeaway is that every individual choice matters. Even a small change like Meatless Monday can have a cumulative impact on the environment and animal welfare.
