The Earth had a twin that collided with us billions of years ago and created remnants from which the Moon created itself. The Moon is essential for temperature regulation on Earth. Jupiter protects us by pulling meteors that might otherwise collide with our planet. Under the Mediterranean are massive salt caves from the number of times the Mediterranean dried up. Who knew?
These and more tidbits, as well as beautiful images will inform and entice and, hopefully, urge planetary eco-action. As author, narrator and scientist Iain Stewart mentions: the planet has recovered and continued to evolve from massive change over the billennia. It’s not the planet that will be destroyed, it is us humans when we dominate the planet in unsustainable ways.
The series Earth: The Biography has been running on National Geographic channel and I highly recommend you take a look. A book and DVDs are available as well. From the description of the series:
This landmark series tells the life story of our planet, how it works, and what makes it so special. Examining the great forces that shape the Earth - volcanoes, the ocean, the atmosphere and ice - the program explores their central roles in our planet’s story. How do these forces affect the Earth’s landscape, its climate, and its history? The final episode argues that Earth is an exceptionally rare kind of planet - giving us a special responsibility to look after our unique world. This is a series that shows the Earth in new and surprising ways. Extensive use of satellite imagery reveals new views of our planet, while timelapse filmed over many months brings the planet to life. Offering a balance between dramatic visuals and illuminating facts, this ground-breaking series makes global science truly compelling.
