Affiliate Disclosure

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: Bird populations in Europe have shown a modest 3% recovery since the 2018 EU ban on harmful neonicotinoid pesticides, demonstrating that environmental protection measures can help restore biodiversity.
📈 One key stat: Insectivorous birds like chaffinches, blackbirds, and black caps experienced a 12% increase in presence following the ban, indicating that eliminating these toxic chemicals allows food webs to recover.
💬 One key quote: “Our results clearly point to neonicotinoid bans as an effective conservation measure for insectivorous birds,” said Thomas Perrot, from the Foundation for Biodiversity Research in France.

1️⃣ The big picture: The European Union banned neonicotinoid insecticides in 2018 after evidence linked them to mass bee die-offs and declining bird populations. These chemicals, introduced in the 1990s, are absorbed into plant tissues making them toxic to insects that feed on them, ultimately affecting the entire food chain. Scientists from the Foundation for Biodiversity Research conducted the first large-scale study to measure the impact of this ban, surveying 57 bird species across 1,900 locations in France. Their findings show a modest but meaningful recovery in bird populations, particularly among insect-eating species.

2️⃣ Why is this good news: The study reveals tangible evidence that policy changes can help reverse biodiversity loss. The 12% increase in insectivorous birds demonstrates that removing harmful chemicals from ecosystems allows wildlife populations to rebound naturally. This recovery happened within just four years, suggesting further improvements may continue as ecosystems heal. The findings provide crucial scientific support for environmental protection measures and show that regulations targeting specific harmful practices can produce measurable positive outcomes for wildlife conservation. Such evidence helps build the case for similar protective policies in other regions facing biodiversity challenges.

3️⃣ What’s next: Scientists emphasize that complete recovery will take time, with estimates ranging from 10-25 years based on previous pesticide bans like DDT. Further research is needed to monitor long-term population trends and determine if recoveries accelerate. Researchers also suggest studying whether bird population recoveries help naturally control crop pests, potentially creating a win-win scenario for farmers and conservation efforts.
