How many animal are kill in a year?

Answer 1

By... what? Humans? Other animals? Natural causes?

By far the biggest cause of death of animals is other animals.... foxes eating field mice, etc.

The number is enormous, but not as enormous as the problem of calculating it. Your question is essentially impossible to answer.
Each year, more than 40 million animals are killed for their fur, for example foxes, bobcats, beavers, raccoons, lynx, and the list goes on and on

Depend on what the animal testing people use!More than 3,000 animals die a yearand more than 4,000 die from animal testing :(Sad fact I know!

God Bless!

Answer 2

More than 100 million animals are reported killed by hunters each year. That number does not include the millions of animals for which kill figures are not maintained by state wildlife agencies.
