Humans are responsible for some of the most dramatic changes on Earth.  Unfortunately, one of them is animal extinction.  Reasons for extinction include hunting/fishing/poaching, the introduction of invasive species, pollution, habitat loss, and climate change.  It’s been said that we are in the midst of the 6th great extinction event, akin to a “biological annihilation“.

Between 1900 and 2015, almost half of the 177 mammal species surveyed lost more than 80% of their population, according to a study by Professor Gerardo Ceballos at the Universidad Nacional Autónoma de México.

Take, for example, lions.  In 1950, it’s estimated that 400,000 lions roamed across most of Africa, southern Europe, the Middle East, and even northwestern India.  Today, there are fewer than 25,000.

In the past 500 years, we know of approximately 1,000 species that have gone extinct, from the woodland bison of West Virginia and Arizona’s Merriam’s elk to the Rocky Mountain grasshopper, passenger pigeon, and Puerto Rico’s Culebra parrot — but this doesn’t account for thousands of species that disappeared before scientists had a chance to describe them.

Here are just 36 extinct animals lost to history due to human activity.
