The Guardian has a tribute to David Attenborough for his 99th birthday on May 8th.  The tribute is a series of 99 birthday wishes from famous people thanking him for his inspiration.

Chris Packham, Presenter, nature activist
It’s all about truth. Ask yourself, “Has David ever knowingly lied to me?” No, never. He may have told us things 40 years ago that science has updated, but he’s always told us the truth. In an age when it’s hard to trust anyone, that stands as his greatest asset.

Barack Obama, 44th US president
I know, from watching David’s programmes, that our ecosystems are all interconnected and that if just one country is doing the right thing but other countries are not, then we’re not going to solve the problem.

Arundhari Roy, Author
He showed how every living thing on this planet is connected to another living thing. Alone, we are nothing. We own nothing, we control nothing except perhaps for the lever that could destroy everything.
