Expedi��o encontra tra�os de coca�na, cafe�na e agrot�xicos na nascente do Tiet�

An expedition along the Tietê River uncovered alarming traces of cocaine, caffeine, and agrotoxins right near the river's source in Salesópolis, highlighting severe environmental degradation. These pollutants, along with microplastics, were found throughout the river, signaling a dire collapse of the river's ecosystem as it reaches the metropolitan area of São Paulo. This discovery underscores the urgent need for comprehensive environmental cleanup and stricter regulations to protect one of Brazil's vital water sources.
