From the frozen poles to the searing deserts, this episode shows how animals have come up with strategies to survive the uneven amounts of sunlight that fall on our planet.
A look at how without volcanoes, there would be no life on Earth. Although destructive, magma from the planet's molten core builds land, and mineral-rich ash from eruptions fertilises the surface.
Weather controls the distribution of freshwater around our planet. In turn, shapes the lives of animals across the globe, rising to an incredible diversity of species and habitats.

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 energizes everything it touches, and powerful volcanoes create and fertilize the land. As a result, there is literally no part of our planet where life can't be found. Written by daniortunogudino
Yet again, Attenborough's A Perfect Planet shines through as the pinnacle of nature documentaries. The footage captured is consistently phenomenal showcasing all the weird and wonderful creatures from the four corners of the planet. The species on show are split between the familiar favourites, to ones never heard of which haven't been captured on camera before, and even shows an interesting light on the types of animals which typically aren't seen as attractive (when else would you want to learn about ants, etc.?). Narration is fitting, the arcs following each of the species are engrossing and often emotional, and the entire thing is educational without ever being dull.
To all those who are complaining that it gets preachy, what did they really expect? It's a documentary about the forces impacting on the animal kingdom, if climate change is radically effecting that, it's going to be mentioned. This should only come across as a lecture if you yourself are not conscious of your environment. Each episode shows the cataclysmic possibilities if things don't change, is it fun to watch? Absolutely not. Is it important and the most concise way to learn these things? Absolutely so. If you don't like it because you find it depressing, you really need to consider the bigger picture.
