Prince Charles is a longstanding advocate for the environment. Over the years, he has utilized his position in the British Monarchy to spearhead actions for a more sustainable future.

In a new essay he wrote for Newsweek, the Prince of Wales made it known to the public how proud he is of his sons, Prince William and Prince Harry, as they follow in his footsteps. He touted their respective works, which all aimed at helping protect the planet, according to Page Six.

Amid tackling the dangers of climate change, he shared how thrilled and satisfied he is that the Wales princes have recognized these threats. As noted, both the Dukes of Cambridge and Sussex have launched various initiatives "to help combat and raise awareness" for the issue.

Prince Charles first acknowledged the works of Prince William in his "prestigious" Earthshot Prize. He said that this move is to "incentivize change and help repair" Earth over the next ten years through technological investments and identifications.

The Duke of Cambridge launched the advocacy through his and the Duchess of Cambridge's Royal Foundation in 2020. The first year was a success as it obtained over 750 nominations across the globe.

The 2021 awards concluded in London last October, with the five winners receiving a total of about $1.3 million. For the 2022 awards, the ceremony will take place in the United States.

After highlighting Prince William's work for the environment, Prince Charles moved on to touting Prince Harry's actions over the years for the same advocacy. He said that the Duke of Sussex "has passionately highlighted the impact of climate change" through his works in Africa and Archewell.

The public would recall that the youngest Wales prince, alongside his wife, Meghan Markle, previously pledged to reach net zero by 2030. They published their plans on the official website of their non-profit organization, Archewell Foundation.

To reach the goal, they will utilize the royal's eco-tourism firm, Travalyst, as well as the Sussex Royals' posts at Ethic.

Following compliments, Prince Charles, then, urged the public to follow his sons' examples and "start doing their part" to save the planet. He emphasized that "time is now," adding that "there is not a moment to lose" as the world enters the new year.

Meanwhile, the praises come amid rumors that the Prince of Wales had a falling out with his youngest son, Prince Harry. It all came after the Duke and Duchess of Sussex shared a bombshell revelation that a senior member of the British Royal Family previously asked about how dark Archie's skin tone would be.

Although the couple did not name names, a source pointed fingers at the next person in line to the British Throne. In his response, though, a spokesperson called the accusations "fiction, and not worth further comment."
