Speaking at a UKTV launch today (September 11), Attenborough described his TV role as a "hangover from the past".
"I suspect in the future you won't need nature jockeys like me," said the British broadcasting icon.
"I also suspect you won't need specialist cameramen who we have at the moment. Nature to film has become easier, easier and easier.
"There are lots of dedicated people out there, who want to do nothing more than film the mating of a dragonfly on a pond only hours from their home. And they'll go home and put it on the web."
He added: "The view of the natural world now will start to come from the web. So paradoxically as human beings become more dominant in the world and more detached from the actuality of the natural world, you'll keep up with it through visions from dedicated amateurs on the web."
Attenborough has created and presented a new series for UKTV channel Eden, Attenborough's Natural Curiosities, which will air in January 2013.
