As Queen Elizabeth scales back her royal duties, Prince Charles is entering the spotlight more and more.

“Charles will accelerate his on-the-job training,” said BBC royal correspondent Peter Hunt (viaExpress).

This more environmentally-friendly ride represents a cause that’s been one of Prince Charles' passions since his youth.

“The uprooting of trees and hedgerows and draining of wet places.”

Besides speaking out in a public forum, the prince has spent decades pursuing environmental concerns in private.

For Charles, a prominent plan of that plan includes organic farming practices.

By 2020, Sandringham was certified organic (viaThe Telegraph).

As reported by Daily Mail, Sandringham is now home to 500 rare-breed cattle.

In deference to local wildlife, electric fences have been eliminated.

To help lessen the estate’s carbon footprint, farm buildings, such as cowsheds, have solar panels.

Sandringham and Highgrove aren’t the only localities that Charles has transformed over the years.

In 2007, the prince purchased Dumfries House in Scotland.

Open to the public, Dumfries includes organic vegetable gardens and is a popular field trip spot for schoolchildren.

“It grows in the ground.

And then they make carrot soup.”
