ReThinking one's consumer behavior and way of life is first essential step to rational natural resources use and transition to Circular Economy. How often do we think of our influence on environment and climate? Do we know how much our comfortable life cost for nature? At this moment we spend more resources, than we have, produce more emissions than the Earth can absorb, pollute oceans with plastics, soils and ground waters with household waste.. we throw away 1/3 of food produced. Such behavior is not only insustainable, but dangerous. ReThink works on Circular Economy principles promotion with emphasis on Design. We urge to move towards conscious consumption, responsible waste handling, we demonstrate and support sustainable innovative solutions, which could be game-changing and give some change to future generations.
