Parents need to know that while the content of this stunning docuseries -- which illustrates Earth's diversity and geological history -- is wholly appropriate for family viewing, it may not really engage younger kids who can't comprehend topics like climate change, plate tectonics, and evolution. They may enjoy the HD footage of oceans, volcanoes, and more; just don't expect them to pay attention for the whole thing. But if you have tweens and teens, this impressive glimpse at the planet's past, present, and future is likely to inspire discussions about global warming, conservation, and the scientific process of studying history.

Families can talk about how the media can be used to teach. What did you learn from this series? How did the host make the information seem personal? What tools did the show use to explain its points? Did those tools help you understand the information? The series also inspires thoughtful discussions about conservation. Why is conservation an important issue? How do humans impact the Earth's ecosystems? What can we do to improve the planet's health?
