Happy Earth Day, everyone! The Earth911 team sits down to talk about the history of Earth Day, the actions each of us can take to support endangered species, reduce our carbon footprints, and improve recycling outcomes across the world. Earth Day 2019 is focused on preserving and educating people about the extinction of species. Next year, the Earth Day Network aims to bring a billion people out into the streets.

Evelyn Fielding-Lopez, Sarah Lozanova, and Mitch Ratcliffe also discuss the evolution of pesticides and the use of natural alternatives that control pests. A great place to start is in your own garden, planting native species to attract birds and monarch butterflies. Are large wind and solar farms a potential location to rebuild pollinator species?

We also look back at some of the most inspiring stories on Earth911 this year, including the story of Health In Harmony's revolutionary approach to preventing illegal logging in Borneo, the Healthy Climate Alliance's efforts to kickstart direct air capture of CO2, and the importance of international treaties to prevent illegal transportation of endangered species as traditional medicine and souvenirs.

There is much to encourage environmental action, and you'll come away from this week's podcast with a raft of good ideas.

In our Earthling Questions this week: Can silicone be recycled? How to recycle motor oil? What to do with used cat litter buckets? Join the conversation and share your thoughts with the community in our Earthling Forum.
