Prince Harry joined his father, Prince Charles, in his recent royal engagement.

Prince Charles hosted a meeting in London to improve the coral reef health as 2018 is the International Year of the Reef. Clarence Palace shared a snap of the Prince of Wales and Meghan Markle's fiancé at the event.

According to The Telegraph, Princes Charles delivered a speech about saving the coral reefs. He also wished to raise awareness of the cause for the new generation. Prince Harry was there to support his father and learn more about coral reefs.

"HRH was joined by Prince Harry, who wanted to find out more about the work being done to protect coral reefs from threats including climate change and pollution," Clarence House announced.

In December, the father and son appeared on Radio 4's "Today" program where Prince Charles admitted that his concern for the environment "probably bored you [Prince Harry] to tears for so many years." But the Prince of Wales was "very proud" and had "enormous optimism" that Markle's husband-to-be had been listening and would strive to help.

Prince Harry shares Prince Charles' passion for nature and the environment. In fact, the Duke is expected to pick up the baton for the environmental campaign from his father. The 33-year-old royal will be an effective advocate for the new generation.

In related news, Prince Harry and Markle visited Edinburg Castle in Scotland on Tuesday. The couple was welcomed by the crowd warmly. Those who traveled to meet the Duke and the "Horrible Bosses" star were very pleased and happy that they did.

"We've come up from Durham to see them, this is the nearest place for us, but it's been worth it," said Ryan Davey, 32, who took his 6-year-old daughter Hannah to see the prince and princess in waiting.

"Just love this couple they don't rush they take the time to stop and shake hands and talk to the crowd that has waited ages to see them," Mo's Sweet Delights wrote. "That's what so great and different about these 2 can't wait for the wedding they've got a great future ahead of them."

In related news, Markle's Meghan Effect was in full swing again. The bag that the "Remember Me" star used from Strathberry was already sold out just minutes after she was seen in it.
