“What difference does this one plastic bottle make?”

– a quote from 7.5 billion people. That’s what it’s about… nothing more and nothing less.

Several million tons of plastic waste end up in the oceans every year and cost the lives of countless sea creatures – because they get caught in old fishing nets and other garbage or unintentionally take up plastic and die in agony.

What do we do?

We want to do something about marine pollution! With every sold product we support the educational work in Indonesia. Because we are of the firm conviction: Only if the public and the local government are sensitized about the consequences of all the plastic waste in the sea can something change.

The core of our vision is that every single person has an influence on the big picture. How good it would be if everyone who is in contact with the MANTAHARI Oceancare brand consumed more consciously and thus produced less plastic waste. It can be a small step for the individual to rethink the use of single use plastic, but it will have greater effects.

Every year, 8 million tons of garbage end up in the sea. Recycling alone is not enough to prevent this unbelievable mass of garbage from rising even further. In our opinion, the only solution is to avoid plastics. On our blog we regularly show tips on how easy it is to do without plastic in everyday life.

Every little positive influence counts, so your influence counts! #yourimpactmatters



The aim of our product sales is to generate money for ocean projects, above all for the MMF. Apart from the purchase price, only the small part that is necessary for the continuation of the project remains with us, the actual profit is donated. Depending on the conditions, the donation amounts vary somewhat, as we have our Apparel line produced on demand and therefore relatively expensive.

In order to still offer full transparency, we indicate the respective donation share of our products in the shop.

About MANTAHARI Oceancare

I am Tim, Divemaster, passionate traveler and business student from Munich.

During my time as a dive guide in Komodo/Indonesia I fell in love with the beautiful underwater world in Southeast Asia. Seeing Manta Rays almost every day “working” has moved something in me that cannot be suppressed, because it is an incredible feeling to dive surrounded by these peaceful animals. But unfortunately you swim together through a lot of plastic garbage. The dramatic thing is that the manta rays glide through the water with their mouths wide open to filter out plankton – it’s almost impossible not to take any plastic.

That was the moment when I realized that I wanted to become active.

I never wanted to be one of those people who saw a problem but then did nothing but feel affected.

Back in my home town of Munich, I had the feeling that I was too far away from the ocean to do anything good against the pollution of the oceans. So I started the social fashion startup “MANTAHARI Oceancare” to draw attention to these important issues and to generate money for our partner, the Marine Megafauna Foundation.

For me, this is the least I can do from here for my favourite place, the ocean.

I am convinced that the influence of each individual person is extremely important and is exactly the point at which change begins. As Sylvia Earle says: “The decisions we make are the ones that make the big difference”.

Let’s start small together and work together to make your influence valuable!


What has happened to our ocean in recent years can be seen everywhere in the media. Everyone is shocked to see images of dying sea creatures and beaches full of plastic. But almost nobody really does anything except realize how bad it all is. Often because you don’t know how to do something about the increasing pollution of the oceans from a distance.

Of course, you can’t expect everyone to become an ocean activist – so we offer to help you on a small scale. By buying one of our products, a large part of the profit – for example 12 Euros for a cap – is donated to our partner, the Marine Megafauna Foundation (MMF). Which part of the total amount will be donated will be explained in the shop for each product.

What to do against the pollution of the sea?How can you avoid garbage and live plastic-free? How do you manage to make your everyday life more sustainable?

On our social media channels Facebook and Instagram we regularly show you facts about the ocean and its creatures, little “life hacks”, how to consume a bit more environmentally friendly and regularly provide food for thought on this important topic.

In addition to the educational work, we are gradually completing donation-based adoptions for manta rays via the Marine Megafauna Foundation. Thus each product of the MANTAHARI Oceancare collection generates money, which is reinvested directly into the conservation projects of the MMF. Not only do you wear a special piece of “Ocean themed” Swag, but you are also an active supporter of the Manta Rays population in Indonesia – embodied by the adopted unique individuals about whom we are happy to keep our sponsors up to date.
