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.

1️⃣ The big picture: Scientists in Brazil are conducting groundbreaking research on the hoary fox, a small canid species found exclusively in the country. Despite being commonly seen in the Brazilian Cerrado grasslands, surprisingly little has been known about these foxes until now. Researchers Fernanda Cavalcanti and Frederico Lemos have spent 20 years studying these elusive animals, tracking their movements with GPS collars and gathering vital data about their behavior and health. Their work is especially critical as the foxes face increasing threats from vehicle collisions, diseases from domestic animals, and rapid habitat loss due to expanding cattle ranches and soybean farms.

2️⃣ Why is this good news: This extensive research is creating the first comprehensive scientific database about hoary foxes, filling crucial knowledge gaps about this unique species. The detailed information about their behavior, diet, and habitat needs provides a foundation for effective conservation strategies. The work helps raise awareness about these little-known animals among local communities and decision-makers. Understanding how these foxes adapt to changing landscapes can help protect not just this species but the entire ecosystem they inhabit.

3️⃣ What’s next: The research team continues their capture campaigns to collect more data on fox populations and monitor their movements through GPS tracking. They aim to better understand how agricultural expansion and landscape changes impact the species’ survival. The researchers are working to build public awareness and empathy for the foxes, recognizing that understanding leads to conservation action.
