"The Stolen Earth" is the twelfth episode of the fourth series and the 750th overall episode of the British science fiction television series Doctor Who. The episode was written by show runner and head writer Russell T Davies and is the first of a two-part crossover story with spin-offs The Sarah Jane Adventures and Torchwood; the concluding episode is "Journey's End", the finale of the fourth series. It was first broadcast on BBC One on 28 June 2008.
The finale's narrative brings closure to several prominent story arcs created during Davies' tenure as show runner. In the episode, contemporary Earth and twenty-six other planets are stolen by the Daleks, aided by their megalomaniacal creator Davros and a shattered but precognitive Dalek Caan. As the Doctor (David Tennant) and his companion Donna Noble (Catherine Tate) try to find Earth, his previous companions Jack Harkness (John Barrowman), Martha Jones (Freema Agyeman), Sarah Jane Smith (Elisabeth Sladen), and Rose Tyler (Billie Piper) convene to contact him and mount a defence against the Daleks. In the episode's climax, the Doctor is shot by a Dalek and begins to regenerate.
The humans living asking more and more
We just don't realize, but the world is full of
treasures
You find them in yourself
The humans are asking more and more
Don't realize, but the world is full of treasures
You find them in yourself
What is necessary for our times today?
We must not do the same mistake
We all live in this blue planet
We live with this blue planet together
I think like that in the place where a nostalgic wind
blows
When this place is gone
It means that we are lost
We're crying for the ideal that can not be thrown away
Our pleasure and sadness are in nature
We are born together, we share the time, and we die
What is necessary for our times today?
We must not do the same mistake
We all live in this blue planet
We live with this blue planet together
This planet is our family
The great nature always defends us
The water, the soil, and a blooming flower
Everything in this blue planet is beautiful
How can we make it dirty?
Can you think of it again?
We are all living in this earth
Where you find a beautiful nature, there is a peaceful
paradise
Let's live our life with all our might
You will shine like this planet
What can we do now?
It's more important to think about the future than look
back past mistakes
