Television’s great presenter believes the critically acclaimed nature series is providing a “form of two-way therapy” in an age when our planet’s health is failing.
More than 12 million viewers have been tuning into the BBC Sunday night spectacular, putting it on course to become the second most-watched TV programme of the year.
Only The Great British Bake Off has been watched by more people.
The never before seen footage of some of Earth’s rarest, scariest and dangerous creatures framed by the latest in television technical innovation has already seen Planet Earth 2 become a classic.
Sir David Attenborough’s peerless commentary has accentuated its charm and authority, yet the doyen of the documentary believes its screening comes at an important time.
He says Planet Earth 2 is “tapping into a similar sentiment” felt across the globe when his iconic Blue Planet was aired in the aftermath of the 9/11 terrorist outrage 15 years ago.
Sir David, 90, told the latest edition of Radio Times magazine: “The viewing figures for Blue Planet were way beyond our expectations.
“Yes, the series was beautifully filmed, but there was something much more significant going on.
“As a nation we craved refuge from the horror and uncertainty, and for an hour on Wednesday evenings our oceans provided that sanctuary.”
Now the environmental threats that stalk the planet are creating a new period of fear and uncertainty.
Sir David said: “Of course, there is no single appalling catalyst as there was in 2001, but our concerns for the world, the confusion we have about its direction of travel, are every bit as great.
“The planet has rarely felt in greater environmental peril.”
By realising that their own wellbeing is connected to that of Earth, Sir David says viewers are “reconnecting with a planet whose beauty is blemished, whose health is failing” and adds: “It”s a form of two-way therapy.”
A new trailer for the show is highlighting even more superlative up close and personal views of nature in all its glory.
The 90-second clip highlights some of the not yet seen footage for the six-part series’ last two episodes that look at Grasslands and Cities.
Among the creatures making cameo roles are the lions of the Okavango Delta, cute harvest mice and Arctic caribou as well as the fastest creature on the planet, the 212mph diving peregrine falcon.
Sir David says some of the other key reasons for the shows success are the way filming technology has allowed much closer views of nature and also how the programme is aired at 8pm Sunday.
He said: “I”m told that we are attracting a larger than normal number of younger viewers and apparently the music of Hans Zimmer in particular is striking a chord with the young. And that pleases me enormously.”
