Sign Sir David Attenborough's Birthday Card

To: Sir David Attenborough

Happy 100th birthday!

For generations, you have brought the wonder of the natural world into our homes – forests, reefs, deserts, oceans, birds, insects, animals and landscapes many of us may never have seen without you.

You have helped millions of us see the Earth not as separate from us, but as a shared home – beautiful, fragile, interconnected and alive.

You remind us that wonder is a way of paying attention. And when we pay attention, we learn to care. When we care, we find the courage to protect what we love.

At a time when so much of the living world is in danger, thank you for showing us beauty without turning away from grief.

We will keep going – for the forests and rivers, the reefs and oceans, the wildlife we share this planet with, and the generations still to come.

With gratitude, wonder and hope,

The Australian public
