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?
  1. First, and most importantly, we still only recommend products that we believe add value for you.

  2. When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.

  3. 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?
  1. When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.

  2. When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).

  3. 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.

Stay impactful,

📰 The quick summary: The Passamaquoddy tribe in Maine has created a community clam garden with 1.25 million softshell clams to restore a culturally important food source that has declined by 85% along Maine’s coast over the past 50 years.
📈 One key stat: Softshell clam populations have declined by an estimated 85 percent along Maine’s entire coast over the past 50 years, threatening both ecosystems and cultural practices.
💬 One key quote: “You could get clams by the bushel. But those days are gone,” said Brian Altvater, a 69-year-old tribe member who remembers digging clams for pocket change during his childhood.

1️⃣ The big picture: The Passamaquoddy tribe in Maine has launched a community clam garden to revitalize softshell clam populations that have been integral to their culture for 13,000 years. Starting with 250,000 juvenile clams in 2022, the garden now nurtures 1.25 million clams across 170 plots. This restoration effort addresses decades of decline caused by overfishing, coastal development, rising ocean temperatures, and invasive green crabs. For the tribe, the garden represents not just environmental restoration but the revival of traditional food practices and economic opportunities that have sustained their community for generations.

2️⃣ Why is this good news: The clam garden project provides a hands-on solution to restore an important marine species that connects the tribe to thousands of years of cultural heritage. Protective netting strategies have successfully defended the growing clams from predatory invasive green crabs, with some plots even attracting wild clam seedlings that boost population numbers. The first community harvest is planned for next summer, which will reconnect community members, especially children, with traditional harvesting practices. Beyond cultural preservation, a healthy clam population can provide supplemental income for local fishers and improved food security for Sipayik residents.

3️⃣ What’s next: Volunteers will continue monitoring the health of the clams and the behavior of predatory green crabs to protect their investment. The community plans to hold its first harvest next summer when the clams reach maturity after their 3-4 year growth period. Erik Francis, the garden’s steward, hopes the successful harvest will inspire former clam diggers in the community to reconnect with this traditional practice.
