A Perfect Planet (DVD)

Narrated by David Attenborough

Planet Earth is perfect. Everything about our world – its size, its distance from the Sun, its spin and tilt, its moon – is perfectly suited to our existence, and our planet’s natural forces perfectly nurture life. A global weather system circulates and distributes fresh water to all corners of the globe, marine currents deliver nutrients to even the deepest reaches of the ocean, sunlight warms and energises everything it touches, and powerful volcanoes create and fertilise the land. As a result, there is literally no part of our planet where life can’t be found.
There are five episodes which include some really fascinating facts:

Volcano: Without volcanoes life on Earth would never have begun. They are responsible for both our breathable atmosphere and our oceans.

The Sun: Life on our planet is solar powered. Every single part of Earth’s surface gets 4,380 hours of sunlight a year, but
in different strengths depending on where you are.

Weather: All the water on Earth, just 3% exists as freshwater, and almost all of that is
locked up as ice or hidden in underground aquifers. Only a tiny fraction of our planet’s water
is held in rivers and lakes

Oceans: They’re home to as much as 80% of all life on Earth, and nearly three billion people rely on them for their primary source of food

Humans: Life on our planet is shaped by the earth’s natural forces, but there is a new force, one so powerful, it is upsetting the balance of life on Earth and threatening our perfect planet – that force is us.
