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,

Over half of the world’s marine species are expected to be facing extinction by 2100. There are already 500 dead zones in the ocean, covering approx. 245,000 km2, caused by overfishing, pollution, and coral bleaching events. Charities around the world are now fighting to save our oceans’ biodiversity before it’s too late. So we had to ask: what are the best charities for marine conservation?

The best charities for marine conservation in terms of overall impact are Oceana and the Marine Conservation Institute. Charities such as Monterey Bay Aquarium and the Marine Mammal Center do amazing work caring for and rehabilitating marine animals in need.

Whether you want to help reduce plastic pollution in our oceans, ban harmful fishing practices, or ensure the world’s most endangered marine species are protected, there is a charity for you. Keep reading to learn more about what the best charities for marine conservation are all about, how they work, and what your best way would be to make a contribution.

Here’s What All the Best Charities for Marine Conservation Have in Common

The charities on this list were chosen based on their mission, impact and transparency ratings, and achievements.

They operate all over the world, from North America to Asia.

Many of the charities on this list focus their efforts on establishing long-term conservation plans for endangered marine animals. Others focus their attention on tackling the plastic pollution problem that kills an estimated 100,000 marine mammals each year.

Yet, they are all deterring harmful fisheries and campaigning for better protection of vulnerable marine habitats.

How Can You Select the Best Charities to Support?

The charities on the list are, we deem, the best charities for marine conservation. However, you may have a particular charity you want to support. Let’s look at what you can do to ensure your contribution has the most significant impact.

  • Check out the charity website. Charities that are worthy of your donations are transparent in their mission and their figures. Familiarize yourself with their history, mission, and values. Their website usually is the best place to start.
  • Identify the charity’s mission. Without a goal, the charity is likely to fail. If the charity’s mission isn’t clear, it’s probably worth looking for a charity that does have a clear mission. 
  • Check if the charity has measurable goals. An effective charity has clear goals. You want to know your donation will help the charity reach its goals. But if it doesn’t have targets, it’s likely to fail or squander your gift. The charity should be able to account for its spending and supply evidence of the work they do.
  • Assess the successes or goals the charity has achieved. You wouldn’t invest in a business if it kept missing its targets. In the same way, charities are like this too. If no one is assessing a charity’s progress in reaching its targets, the chances are they’re not making a substantial positive change.
  • Check the charity’s financials and stats. Trustworthy organizations will publish financial statements and reports each year. Some might be exempt from having to do so, but they should be able to provide them to public members who are interested in donating.
  • Locate sources who work with or benefit from the charity. Word of mouth and first-hand experience of a charity’s work lets you know the charity’s quality. If you’re able to do so, check out the charity for yourself or speak to someone familiar with it. This way, your donation will go to the right place. 

How Can You Best Support These Charities?

After you’ve made your decision, it’s time for you to decide on how you’d like to help the charities you’ve chosen. Check how you can help – each charity runs specific programs that have unique aims. Find out what the aim of such programs is and whether they are right for you. 

Here are a few ways you can help your chosen charity:

  • Donate money. You can find donation pages on the website of most charities. Your donation can be a one-time payment, or you can set it to be deducted regularly at different intervals. You can mostly pay via credit card, but some charities also take PayPal or Bitcoin payments.
  • Buy their official merchandise. The charities can also raise money by selling merchandise. So, you can support them by buying the mugs, shirts, caps, pens, pencils, and any other such items they may be selling. Ideally, you should buy as much as you can to share and spread the word about the charity’s activities.
  • Engage in volunteer work. As you’ve seen from our descriptions above, some charities engage in a lot of local and grassroots programs. You can help by taking on and organizing the program in your local area.
  • Help their fundraising efforts. You can spread the word about the charity in your workplace, school, church, etc., and hold creative fundraising drives on social media or offline within your small circles.
  • Share their stories. Most charities have compelling stories that you can share with your audience to attract more people to the cause.

Final Thoughts

Now it is up to you to select the charity that resonates most with you. And whichever charity you end up choosing and contributing to, we are sure that they will immensely appreciate your support. Hopefully, the information within this article has made this selection process a bit easier for you to support charities dedicated to marine conservation – based on the causes that matter most to you.

Stay impactful,
