190: Empowering Conservation with Brett Jenks: Rare’s Global Impact on Climate and Sustainability
In this episode, we talk to Brett Jenks, who leads Rare, a global organization empowering communities to protect and manage natural resources sustainably. As CEO, he has driven initiatives like Fish Forever—the world’s largest coastal fishery recovery effort—and has blended behavioral science with community-led conservation, expanding the organization’s reach to over 60 countries to address climate change, biodiversity loss, and sustainable agriculture. He has also extended this work into the for-profit sector with The Meloy Fund. Additionally, he is a Catto Fellow, Braddock Scholar, McNulty Prize laureate, and trustee of the Grantham Trust. His commitment to our planet has earned him global recognition, including the Rose-Walters Prize for Environmental Activism.
During this episode, we explore Rare’s innovative approach to conservation, including how behavioral science and community-led efforts are transforming global environmental action. We discuss lessons from partnerships, the role of impact investing, and the potential of tech innovations like the EverForest game. Plus, we uncover practical steps listeners can take to support conservation and examine the decisions that have shaped Rare’s impact under his leadership.

About the author, Mariska
Hi, I’m Mariska – podcast host, artist, sustainability advocate and consultant, and storyteller driven by a deep passion for our planet. Sustainability isn’t just a topic I discuss; it’s a way of life I embody through my work, actions, and everyday choices.
My journey began several years ago when I started experimenting with trash as a medium in my artwork. What began as creative curiosity quickly turned into a deep dive into the environmental impact of waste. That curiosity expanded into a broader connection with nature—including a life-changing trek to the summit of Mount Kilimanjaro, where I found both clarity and purpose. It was there that I made the decision to leave the corporate world behind and commit fully to environmental work.
In 2018, I took that message public in the UAE by wearing every piece of trash I generated for 30 days. The result—65 kilograms of waste—sparked national conversations around sustainability and waste reduction. That bold experiment also became the catalyst for my podcast, Mama Earth Talk, where I’ve since connected with global thought leaders to explore sustainability and inspire meaningful action.
Over the years, I’ve collaborated with organizations such as Nespresso, Costa, and Dubai International Airport to implement practical and impactful environmental solutions. From optimizing waste management systems to leading awareness campaigns, I specialize in designing strategies that create real, lasting change.
My artwork—blending environmental advocacy with creative expression—has been collected by public figures including comedian Trevor Noah, environmentalist Adrian Grenier, entrepreneur Gary Vaynerchuk, radio host Kris Fade, Grammy Award-winning DJ Black Coffee, and NBA player Mason Plumlee. Through public speaking, podcasting, and art, I aim to inspire individuals and organizations to rethink their relationship with the environment.
With over a decade of international experience in design and project management across Australia, South Africa, the UK, India, and the UAE, I bring a unique mix of creativity and strategic insight to sustainability challenges. My global perspective allows me to collaborate across cultures, drive innovation, and empower others to make a meaningful impact.
As a lifelong learner and passionate advocate, I focus on practical, holistic solutions to environmental challenges—guided by systems thinking and a deep commitment to action. I hold a BA in Design, a postgraduate degree in Environmental Science, and a Master’s in Sustainable Design.
