Sustainability assumes that resources are finite and must be used conservatively and sensibly, taking into account long-term priorities and the consequences of the way resources are used. Sustainable practices support ecological, human and economic health and vitality. This series refers to the current problem experienced in the oceans and seas. They represent 50% of oxygen production in the world and today they are also affected by the increase in global temperature, pollution, among others, which also promotes the extinction of species and changes, for example, in pH. Other problems are associated with excessive fishing, whether for food or illegal hunting of some species, environmental problems associated with pollution and microplastics lead us to a chaotic problem, such as large floating plastic islands, which not only affect the fish but also the that we eat at the table. The series was created in a sustainable way, using colored cards, reused masks, plates and cutlery, empty cans and tries to create warning signs for these situations.
