Hopika works to promote more environmentally responsible behaviors for the benefit of nature by addressing the issue of littering. The association has two main missions: • It identifies critical zones in terms of littering (with a major focus on cigarette butts) through litter collection activities. • It proposes concrete, tailored solutions to facilitate more environmentally responsible behaviors: awareness stands, educational event ashtrays, personalized pocket ashtrays, and on-site awareness campaigns (marking storm drain grates, sculptures/trash bins, signage, etc.) The association is guided by two main principles: • "Let us work together so that the adults of tomorrow are the heart and lungs of our actions." • "Because it is the source of all life, at the heart of our actions, let us work together to preserve it." Hopika is an officially recognized non-profit organization of public interest.
