This is the Guardian.

Tomorrow is Sir David Attenborough's 100th birthday.

It's astonishing to imagine how different the world was when he was born, and the changes he's witnessed.

If you'd have gone onto the streets of London,

you would have seen men in bowler hats and flat caps,

horse-drawn carriages,

and perhaps heard jazz floating out from a nearby gramophone.

And in the countryside,

calls of nightingales and cuckoos echoing through the woodlands.

The BBC, where Attenborough eventually found his home, launched its first ever regular television

service when he was 10 years old.

He's lived through the Second World War,

the invention of the nuclear bomb,

the swinging 60s, Watergate, the space race,

the internet and the rise of computers.

Over the past century, we've transformed our planet

and in doing so, reshaped the natural world.

The world depends upon plants

and we treat them with so little thought

and so little care

and exterminate them without little thought or care

and we will pay the price.
