WATCH: Planet Earth II's emotional finale and David Attenborough's plea

Planet Earth II attracted more viewers than The X Factor final last night; thanks to a series full of mindblowing moments that were captured by an extremely talented BBC film crew and editing team.

The legendary Sir David Attenborough did a fantastic job describing the scenes and allowed us to enjoy the thrills of nature week on week. But in the final episode, he made a heartfelt plea to us to take a moral responsibility for our impact on the envrironment.

After showing us so many incredible moments, the 90-year-old TV star reminded us that our future depends on the natural world.

Sir David, from the top of The Shard in London, addressed the camera and said: “Only a small number of animals have managed to find ways of living alongside us. And every ten years an area the size of Britain disappears under a jungle of concrete. But it doesn’t have to be like this. Could it not be possible to build cities more in harmony with nature?

“Now over half of us live in an urban environment. My home too is here in the city of London. It’s also sobering. It reminds me of just how easy it is for us to lose our connection with the natural world.

“Yet it’s on this connection that the future of both humanity and the natural world depend. It’s surely our responsibility to do everything within our power to create a planet that provides a home not just for us, but for all life on Earth.”

One example of the impact our cities have on the natural world aired last night. Viewers watched as newly-hatched hawksbill turtle, pictured below, were filmed walking to their deaths, into a busy road because they were confused and disorientated by the street lights. The turtles should have been following the moon’s reflection into the sea.

Because Planet Earth’s crew are never filmed intervening with the wildlife they observe, distressed viewers were left non-the-wiser as to the fate of the baby turtles.

However, a statement on the BBC’s Planet Earth Twitter confirmed the camera men rescued the animals from the oncoming traffic, announcing on their account: “Every turtle that was seen or filmed by the #PlanetEarth2 crew was collected and put back into the sea.”
