More To The Story: As NASA’s Artemis II journeyed into space earlier this month, one of the astronauts took a photo of Earth lit by the moon known as “Hello, World.” It’s the first published photograph of our planet taken by a human since 1972. The Artemis mission has reinvigorated mankind’s awe of our planet. But for Earth to remain a habitable place for humans to flourish, it requires us to take care of it.

On this special Earth Day episode of More To The Story, we’re featuring interviews with three influential environmental leaders: former Vice President and founder and chairman of the Climate Reality Project Al Gore; longtime activist Catherine Coleman Flowers; and journalist, author, and activist Bill McKibben. All three acknowledge the challenges of fighting climate change to protect our planet, especially at a time when the Trump administration is rolling back federal environmental protections. But they’re surprisingly hopeful about our capacity to protect the Earth for future generations.
