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. We’re looking for new submissions to the Outside/Inbox! Give us your weirdest, nichest, most bizarre questions you can think of.
