  • Reproduce the core statement of Planet Earth (franchise) from memory before moving on to harder problems.

Reference excerpt

Planet Earth is a television and film documentary franchise produced and broadcast by the BBC. The franchise began in 2006 following the success of The Blue Planet.

Development In 2001 the BBC broadcast The Blue Planet, a landmark series on the natural history of the world's oceans. It received critical acclaim, high viewing figures, audience appreciation ratings, and many awards. It also became a hugely profitable global brand, eventually being sold to 150 countries worldwide. Feedback showed that audiences particularly liked the epic scale, the scenes of new and unusual species and the cinematic quality of the series. Programme commissioners were keen for a follow-up, so Alastair Fothergill decided that the Natural History Unit should repeat the formula with a series looking at the whole planet. The idea for Planet Earth was born, and the series was commissioned by Lorraine Heggessey, then Controller of BBC One, in January 2002. A feature film version of Planet Earth was commissioned alongside the television series, repeating the successful model established with The Blue Planet and its companion film, Deep Blue. Earth was released around the world from 2007 to 2009. There was also another accompanying television series, Planet Earth: The Future, which looked at the environmental problems facing some of the species and habitats featured in the main series in more detail.

Spin-off television series

Planet Earth: The Future (2006)

Planet Earth: The Future is a 2006 BBC documentary series on the environment and conservation, produced by the BBC Natural History Unit as a companion to the multi-award-winning nature documentary Planet Earth. The programmes were originally broadcast on BBC Four immediately after the final three episodes of Planet Earth on BBC One. Each episode highlights the conservation issues surrounding some of the species and environments featured in Planet Earth, using interviews with the film-makers and eminent figures from the fields of science, conservation, politics, and theology. The programmes are narrated by Simon Poland and the series producer was Fergus Beeley.

Saving Planet Earth (2007)

Saving Planet Earth is a season of nature documentaries with a conservation theme, screened on BBC Television in 2007 to mark the 50th anniversary of its specialist factual department, the BBC Natural History Unit. The series featured films contributed by a number of celebrities on the plight of various endangered species, and coincided with the launch of the BBC Wildlife Fund, a charitable organisation which distributes money to conservation projects around the world. The television series culminated in a live fundraising telethon on BBC Two, hosted by Alan Titchmarsh, which raised over £1 million for the charity. The BBC broadcast a second live telethon in 2010. Wild Night In was presented by Kate Humble, Chris Packham and Martin Hughes-Games and featured conservation projects which had benefited from the support of the BBC Wildlife Fund. This helped to raise a further £1 million.

Worked examples

Example 1 — a first encounter with Planet Earth (franchise)

Start with the simplest possible case. Write down what Planet Earth (franchise) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Planet Earth (franchise) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Planet Earth (franchise) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Planet Earth (franchise)

In research
Planet Earth (franchise) appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Planet Earth (franchise) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Planet Earth (franchise) is common in secondary-school and first-year university syllabi. It links to neighbouring topics BBC high definition shows, BBC television documentaries, Documentary films about nature, so understanding it makes those chapters shorter.
In everyday life
