Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: A new documentary film chronicles the efforts to restore Hong Kong’s vital oyster reefs, showcasing how these ecosystems can enhance water quality and marine biodiversity in the Pearl River Delta region.
📈 One key stat: Individual oyster reefs can filter millions of liters of water daily while providing essential habitats for countless marine species.
💬 One key quote: “Their findings suggest that not all is lost, and if restoration efforts are implemented at scale, oyster reefs could flourish once more.”
1️⃣ The big picture: A groundbreaking documentary titled ‘City of Shells: Our Forgotten Oyster Reefs‘ is premiering in Hong Kong, highlighting the critical role of oyster reefs in marine ecosystems. The film, produced over three years, documents seven years of research and conservation work across Hong Kong and the Pearl River Delta region. Through historical research and scientific exploration, it reveals how oysters shaped the region’s development and supported thriving marine ecosystems. The documentary follows researchers, restoration ecologists, and marine scientists as they work to locate and potentially restore these vital habitats.
2️⃣ Why is this good news: The documentary reveals promising opportunities to revive Hong Kong’s oyster reefs and restore marine biodiversity. These ecosystems serve as natural water filtration systems and provide essential habitats for numerous marine species. Restored oyster reefs act as natural barriers against storms and coastal erosion, enhancing the region’s resilience to climate change. The research demonstrates that targeted conservation efforts can help bring these crucial marine ecosystems back to life.
3️⃣ What’s next: A screening of the documentary takes place on May 12th, 2025, at The Hive Studios in Kennedy Town, Hong Kong. After the screening, a Q&A session with key experts including TNC Hong Kong Marine’s Associate Director of Conservation and the Executive Producer will share insights on reef restoration.
