—user summary
Jenga Ocean is the first board game to be made from recycled plastic fishing nets.
Discarded fishing nets have been identified as the most harmful form on plastic pollution in the ocean. Endangering sea life, discarded nets entangle thousands of marine mammals each year. By supporting the collection and recycling of these harmful materials, Jenga Ocean helps protect sea life and marine ecosystems.
Jenga Ocean is made from over 25 square feet of recycled fishing nets, proudly sourced from Bureo's recycling program. Founded in 2012 by surfers who love the ocean, Bureo works with communities along the coast of Chile to collect and recycle discarded fishing nets.
