I personally find the "animals killed since you opened this page" number to be the most unsettling. YTD numbers are so large, I find them hard to process.
If you choose to eat meat, please be aware of the conditions most of these animals exist in and how they die. I'll spare you more numbers, because they don't do the cruel reality justice anyway. Instead, I'll leave you with some video material: https://animalequality.org/blog/factory-farming-facts/
