Introducing Hanli Prinsloo: Freediving champion, ocean adventurer, and sustainability advocate

Chartwell is thrilled to be representing Hanli Prinsloo exclusively for her global speaking engagements.

An 11-times South African freediving record holder and one of the world’s foremost ocean adventurers, Hanli’s career has seen her freedive with marine megafauna from blue whales to tiger sharks.

In her inspirational speeches, Hanli shares the lessons freediving has taught her about mind over body control and mental toughness – lessons she continues to impart to elite athletes all over the world, including the South African Rugby Sevens team. She offers her audiences with an entirely new framework through which to think about risk, and enables them to challenge fear and limiting assumptions in all walks of life.

Hanli is also Founder and CEO of the I Am Water Foundation, an organisation that campaigns for ocean conservation through education programmes and documentary films. She has been made a WEF Young Global Leader in recognition of this pioneering work.

Ocean advocate and adventurer Hanli Prinsloo visits Cocos Island to promote shark understanding and protection

Hanli Prinsloo, ocean adventurer and world champion freediver, took a trip to Cocos Island to promote shark understanding and protection.

The purpose of this trip was to address the decision makers in Costa Rica, who have allowed for an exception to the law against fishing for sharks. Costa Rican authorities claim that if sharks were a bycatch – including in the marine reserve of the Cocos Island, a hotspot for amazing shark diversity – they could be legally exported (shark fin soup is seen as status enriching in China).

However, conservationists warn that allowing exceptions to what should be tight restrictions on the shark fin trade, boosts that temptation. Furthermore, CITES mentions bycatch as one of the top threats to hammerhead shark populations worldwide. In response to this law exception, Hanli and her team have gone to explore, document and share stories from a magnificent underwater wilderness, and put shark protection back on the agenda.

The Washington Post profiles Joel Salatin, America’s most famous farmer and inspirational speaker on sustainability

Joel SalatinJoel Salatin, America’s most famous farmer and inspirational speaker on sustainability, was featured in the Washington Post, outlining how his methods and philosophy have won him followers from the left, centre and right.

Joel was catapulted to fame after being featured in Michael Pollan’s 2006 best-seller, “The Omnivore’s Dilemma,” and the 2008 award-winning documentary “Food, Inc.” He is a prominent and admired leader in the global sustainable-food movement; “Everybody eats, and the movement’s most basic tenets — food should benefit our health, farming should benefit our environment, food systems should be transparent — have wide appeal.”

Described by Pollan as the most “influential farmer in the country right now,” much of the reason for that is the innovative methods Joel has devised for raising cattle, pigs and poultry in symbiosis with one another and the pasture beneath them. Those methods have proved productive and profitable, and are based on mimicry of natural systems rather than constant chemical inputs.

On the speaking circuit, Joel is noted as “a performer, with a flair for the dramatic and a tendency to lob bombs from the lectern. Massie likens Salatin’s ability to inform while entertaining to that of Glenn Beck. Salatin’s more liberal fans might prefer a Jon Stewart comparison.”
