Happy Earth Day, listeners! On this special episode we talk about four cool animals that have been impacted by humans and climate change: the dodo bird, Tasmanian tiger, white lemuroid possum, and Fernandina giant tortoise. Through hunting, climate change, introduction of non-native species, and more, these animals have been brought to the brink of extinction, and sometimes even have gone extinct.

We end this episode with practical ways that you can make a difference for animals and for our environment.

By the way, the 200 million number on straws is probably very low--but we can't find an accurate number for how many straws are used every year.
