Queen Elizabeth is set to reduce the amount of plastics used across the Royal Household, after meeting with Sir David Attenborough.

The 91-year-old monarch met with the 'Blue Planet II' presenter, also 91, back in November as they filmed a documentary about a conservation project called the Commonwealth Canopy together, and the Queen is believed to have been so moved by his passion for cutting back on plastic usage that she's made the decision to eliminate the material from the Royal Estate.

A Palace spokesman indicated the Queen had taken a personal interest in the reduction of plastic, saying: "Across the organisation, the Royal Household is committed to reducing its environmental impact."

The affected households include Buckingham Palace, Windsor Castle and the Palace of Holyrood house in Edinburgh.

David is known for his campaign to encourage people to stop using plastic products as they often end up in the world's Oceans and cause permanent damage to marine life.

And he isn't the only passionate about the subject, as the Queen's own son Prince Charles, 69, recently delivered a speech at a meeting for the International Sustainability Unit (ISU) where he warned the "nightmare result" of plastic pollution in the world's oceans is set to get "worse".

He said: "The nightmare result of eight million tonnes of plastic entering the ocean every year is set to get worse rather than better. We cannot, indeed must not, allow this situation to continue ... I do fervently pray that you will all do your utmost to work together in the coming year to make real, substantial progress. It could not be more critical that you succeed."

Although Charles notes that ridding the ocean of all plastic is a large task, he is "encouraged" by the fact that the topic is now "very much on the global agenda".

He said: "Even though the challenge at hand is extremely grave and unbelievably urgent, I for one at least find some encouragement from the fact that the legacy of plastic in the environment is now very much on the global agenda and in the public consciousness."
