/ @atilaiamarino Water is an essential resource for life, in addition to having great economic importance and directly impacting the quality of life of all of us. From Brazil's Independence to ancient civilizations, water was present in various historical moments of humanity. With the increasing demand for water for consumption, industry and agriculture, it is becoming a scarce resource, mainly due to the global climate changes we have caused. In today's video, Atila Iamarino tells us about the causes and effects of the water crisis that can affect humanity, even in regions like Brazil, where fresh water is an abundant resource. This is the fourth video in a series of 12 episodes that will address the Environment and Sustainability in Brazil.
