Once known as “Vince” on HBO’s Entourage, Adrian Grenier is deeply concerned about the health of our oceans.He co-founded the Lonely Whale Foundation in 2015.The #stopsucking challenge aims to fight plastic pollution in oceans by decreasing everyday use of plastic straws. Sometimes humans invent things, seemingly benign things, that end up having profound and unpredictable effects. The invention of plastic must have been a marvel in the early 20th century. Entrepreneurs scrambled to build new things and innovate on the old, new technologies developed, and everyday life quickly underwent a huge shift. Plastic is now, quite literally, everywhere. It’s on land and in the oceans (even inside the fish inside the oceans). Scientists are regularly documenting unforeseen side effects, great and small, of our reliance on plastic, like how plastic microbeads from our toothpaste and face wash are decreasing sperm counts in oysters. Plastic pollution is yet another unintended consequence of human invention and innovation. The impacts on our natural environment are profound, but will we have the plasticity to shift away from our reliance on this synthetic material? Adrian Grenier, main act in HBO’s Entourage, founded the Lonely Whale Foundation in 2015 to promote education and awareness on ocean conservation issues. These days he is focusing his energies on what he considers to be one of the “suckiest” parts of plastic pollution — straws. Coral landscape in Komodo, Indonesia. Photo by Rhett A. Butler. AN INTERVIEW WITH ADRIAN GRENIER Mongabay: Who or what inspired you to get involved in conservation? Adrian Grenier: I was lucky enough to be raised by a mother who cared deeply for our Earth and all of its creatures. From a very young age she taught me the importance of caring for our shared environment, starting with cleaning my room. Now, my room is the world and I intend to fulfill my responsibility to keep it clean and also inspire others to do the same. Mongabay: What environmental issue is most important to you right now? Why did you co-found the Lonely Whale Foundation? Adrian Grenier: In the last few years the ocean has been my main area of focus. When I was younger, I fought for every issue, animal, habitat… you name it! But I realized that our ocean is so vastly underserved yet it is the heart of our blue planet. That is why I co-founded Lonely Whale Foundation with my producing partner Lucy Sumner, to reconnect all people to our ocean through inspiration and tangible action. No matter if you live on the beach or in a landlocked town, we are all capable of becoming ocean advocates. Mongabay: Tell us about the Strawless Ocean initiative. What’s the problem with plastic straws and why do we all need to #stopsucking? Adrian Grenier: Single-use plastic straws are our “gateway plastic” into the plastic pollution conversation. Many of us have no need for single-use plastic straws, and what’s worse is that many are not recyclable. We use 500 million plastic straws every day just in the U.S. and scientists have projected that by 2050 there may be more plastic in our ocean than fish. Those are two pretty overwhelming statistics. For many, it can be an insurmountable task to begin to tackle this problem. That’s why Lonely Whale has teamed up with 40-plus NGO partners to form the Strawless Ocean initiative. Together, we are addressing plastic pollution by starting with one item: the straw. Because if it’s just one thing we can all #stopsucking, right?! Mongabay: Does the effort aim to ban the use of plastic straws? How will we keep ice cubes from bumping our noses annoyingly? Adrian Grenier: Our primary goal is to provide alternative options, either marine degradable (paper) or re-usable (metal or glass). If we can begin to understand the impact of our daily habits through an alternative straw, we view that as a key metric of success. For example, in our Strawless In Seattle campaign our 200+ partners have opted to use paper straws to champion the cause. In addition to presenting individuals and businesses an alternative, it is really important to know that for some in the disability community plastic straws are necessary. For that reason we’re working with key partners in the Strawless Ocean initiative to ensure that new legislation regarding sale or use of plastic straws appropriately recognizes their needs. I pledge to #stopsucking! @LeoDiCaprio, will you join me? https://t.co/uux7o9ODPW — Sylvia A. Earle (@SylviaEarle) August 10, 2017 Oceanographer Sylvia A.

Mongabay: We cover ocean issues regularly at Mongabay. Which marine topics do you think are the most underreported? Adrian Grenier: Plastic pollution has earned a place in the spotlight the last few months but it’s still critical to continue to educate more people to [make a] measurable impact. Illegal and overfishing is another big problem. Again, as consumers we have incredible power over this problem: we can refuse seafood that has been illegally caught or fished from a stock that is unsustainable. It starts with education, awareness, and holding one another accountable. Mongabay: What are your goals as a newly appointed U.N. Environment Programme (UNEP) Goodwill Ambassador? Adrian Grenier: I am committed to working across the public and private sectors to facilitate measurable global impact that shifts our culture from one of conspicuous consumption to conscious sustainability. This past February I helped UNEP launch their Clean Seas campaign, which inspires individuals, organizations, and government actors to come together and collaborate on radical solutions. You will see much more of this radical collaboration throughout my work with the U.N. Adrian Grenier, actor and environmental activist. Photo courtesy of Adrian Grenier.
