| British naturalist David Attenborough, 92, who 
				narrates the series, hosted the event at London's Natural 
				History Museum.
 Charles, who paid tribute to Attenborough's work, made his first 
				speech on the environment in 1968 and has long warned of the 
				dangers of human damage to the natural world.
 
 "What I want to know is how can we possibly sacrifice our 
				children's and grandchildren's entire future, let alone the 
				future of all life on this miraculous planet by not doing what 
				is required now," he said in a speech at the event.
 
 He said he hoped "Our Planet" would educate hundreds of millions 
				of people around the world about what action was required. 
				Charles also said it was a source of great pride that both his 
				sons had taken up the cause of conservation.
 
 The eight-part series, which showcases the natural world and the 
				threats it faces, will be released on Friday.
 
 Produced by the makers of the award-winning "Planet Earth" show, 
				it takes viewers from glaciers to jungles, looking at how their 
				animal inhabitants are challenged by changes in climate, 
				surroundings and human actions.
 
 "Don't be extravagant, don't waste, do what you can to cut out 
				unnecessary expenditure, don't eat more than you need, don't 
				travel more than you need," Attenborough told Reuters at the 
				premiere when asked what his message would be to the world.
 
 "Be responsible careful citizens of this planet which is our 
				only home, and for the creatures that live in it."
 
 More than 600 crew members were involved in the four-year 
				project, filming in 50 countries.
 
 Attenborough, who has helped raise awareness of plastic 
				pollution in the sea, said he hoped the show's message would 
				resonate worldwide through the streaming service's global reach.
 
 "The problem is worldwide and the solution has to be worldwide," 
				he told Reuters in an interview ahead of the premiere. "It is a 
				world thing, that's why this distribution of this is so 
				important. The thought that it will be seen around the world is 
				very, very important."
