Z is for... Zigzag river From where it is born, the TietĂŞ River makes a zig-zag path until the end in SĂŁo Paulo city. In this zig-zag we see lots of trash and wastes, but also, many beautiful areas with fish and waterfalls.
In some areas the river is like the picture above, and sadly in other areas the river is like the picture shown below.
