Earth Day invites us to pause, appreciate and celebrate the planet we all call home. It's also a moment to talk about environmental conservation and climate solutions.

Marine biologist and author Ayana Elizabeth Johnson explores those solutions in her book, "What if We Get it Right?: Visions of Climate Futures."

We sit down with Johnson ahead of an event this Friday at UC San Diego's Scripps Institution of Oceanography to celebrate the launch of a new paperback edition.

Plus, Olivewood Gardens and Learning Center promotes community gardening and sustainability through hands-on education in National City. We sit down with two specialists involved with the program.

And, local organization Red Earth Movement draws on Indigenous wisdom to teach community members about permaculture and sustainable farming through their "Seed to Spirit" program. We hear from its founder.

Guests:

• Ayana Elizabeth Johnson, marine biologist and author of "What If We Get it Right?: Visions of Climate Futures"
• Miah Tatola, environmental education specialist, Olivewood Gardens & Learning Center
• Birdy Rivera Almansa, garden and nutrition education specialist, Olivewood Gardens & Learning Center
• Adam Uribe, indigenous permaculturist and founder of Red Earth Movement
