Specifically, the near-extinct Iberian Lynx. I know people will whine about why she didn't leave the money to human causes, but I'm proud that she did it. I'm especially proud that she is Spanish.
I get so tired of people calling for money to human charities. Humans control the frigging WORLD. They run the governments, they run businesses, they run everything. And they still don't have enough money! That's a problem with humans as a species, not with specific people like this woman. They are a tiny minority. Stop blaming general human selfishness on people like her.
