There’s few certainties in life. But the sun will always rise, the seasons will change, and the Outside/Inbox will forever remain answered.
From lighthouse paint hues to polar bear lovers, this week the team takes up your questions on all things red.
- What makes cardinals red?
- Why do albino animals have red eyes?
- Why are so many lighthouses painted red?
- Do our dogs love us?
- Do some animals have same-sex relationships?
- How do environmental changes affect pair-bonding?
Featuring Alex Funk, Jeremy D'Entremont, Karyn Anderson, and Francesco Ventura.
Thanks to Outside/In listeners Liz, Tyler, Monica and Lera for their questions.
