One wrote: "I can remember my dad talking about 'Prince Charles' championing the natural world, climate, looking after our planet many years ago, and how it seemed he was taking on such a battle that most didn't understand. My dad taught me how important it was, and still is, and thankfully now more people can see that he was beating the drum ahead of the rest."

Another fan echoed the same sentiment: "I've always admired how ahead of the times the King was and championed for the environment so very passionately at a time when it was on NOBODIES radar!

"Seeing the two greatest men in our wonderful country, together at the same time for a shared purpose, is so very inspiring. Thank you, both."

On February 19, 1970, His Majesty, as Prince of Wales, in the sea, during a speech at the 'Countryside In 1970' conference.

King Charles, a lifelong environmentalist, walked the 'blue carpet' at London's Royal Festival Hall last night before meeting the beloved natural history TV presenter Sir David Attenborough.

The naturalist, from over 83 different countries, shows why ocean recovery is vital for stabilising the climate, securing a healthier future for the population, and how marine protection, if immediately implemented, can help to turn the tide of the damage.

The King has met Sir David several times before as his work as an ambassador for the natural world and his passion for the planet overlap with the King's own work to promote sustainability and protect nature and the oceans.
