You may have seen him swim more than 191 km for Nature last summer; he is now setting off to conquer mountain summits... For the 5th consecutive year, Swiss eco-adventurer Noam Yaron is taking on the challenge by giving the cause a voice in the media and mobilizing his community of more than 830,000 followers on social media.
To create a strong signal and amplify our media impact for collective awareness.
By finding partners to turn cigarette butts into a resource and follow through on our commitment, all the way down the chain.
To sustainably grow the initiative and reflect the global scale of cigarette butt pollution.

It is also possible to organize themed talks with Noam Yaron, with proceeds going entirely to the Water Lover Challenge.
This year, to make the clean-up even more educational, we are providing a communication and awareness kit on cigarette butts and the issues they raise.
