Prince William's well-received conservation documentary, A Planet For Us All, continues to reap praises that it might inspire Prince Harry and Meghan Markle to produce a similar program for Netflix.

A royal commentator believes that Prince Harry and Meghan will also come out with a climate change documentary. It's not going to be surprising since many members of the royal family have expressed their support for this pressing global issue. 

Royally Obsessed podcast host Roberta Fiorito said that she expects Harry and Meghan to follow in Prince William's lead and do a documentary about the environment.  The royal expert said that despite the similarities in advocacy -- in this case it's the conservation of the planet's resources -- it is actually good to see both Harry and William take on this problem to raise awareness and increase people's interest.

What makes this even better is that their father, Prince Charles, is also into conservation and is hailed as a pioneer in eco-issues. The royal commentator said that if the three biggest personas in the House of Windsor -- Charles, William and Harry -- have chosen this particular cause then it can only bring more good things for the environment.

Royal author Nigel Cawthorne also thinks that Harry and Meghan will copy Prince William's documentary because of one factor: their shared passion for the environment. Prior to stepping back from his royal duties, Harry had an eco-advocacy with Travalyst, which promotes eco-conscious trips.   

However, both royal commentators highlighted the key difference between Harry and Meghan's upcoming conservation documentary compared to Prince William's A Planet For Us All. Fiorito and Cawthorne believe that the contract with Netflix can either be a good and bad thing for the Sussexes. 

Fiorito said that Harry and Meghan's documentary will have a commercial gain attached since it's a partnership with the streaming platform. Cawthorne, on the other hand, said that William's documentary was surprising since it showed how he is closely aligned with Princess Diana's advocacy to do something good for the world without getting political.

But it's still unclear what type of environmental documentary Prince Harry and Meghan Markle will produce since the couple haven't started with it. The Sussex pair did say, however, that they plan to release family-friendly content for Netflix to reflect their advocacies, which includes the environment.

Prince William: A Planet For Us All, on the other hand, aired on ITV in the first week of October and it's still accessible via ITV Hub or through Amazon Prime subscribers.
