Brazil's clearwater Tapajos river polluted by illegal gold mining

        he browning of one of Brazil's largest clearwater rivers, the Tapajos, is almost certainly due to the mud and sentiments churned up by increasing illegal gold
        mining, federal prosecutors and environmental activists said on Monday.
        
        Once called the "Blue River" because of its pristine condition and clear waters, the Tapajos has drawn a rush of gold miners since 2019 as world prices soared and environmental enforcement faltered under Brazil's far-right government.
        
        The illegal miners use mechanical shovels to knock down trees and dig pits, and dredging barges that vacuum river beds, sucking up mud and water as they search for gold.
        
        Chocolate-colored water can be seen for hundreds of kilometers in aerial photographs, flowing out of tributaries and down the Tapajos to its confluence with the Amazon river.
