Orinoco River Basin
A river is just a river like any other, unless it is a busy and polluted waterway, in which case, it is not just a river anymore. Take the Orinoco river basin; this freshwater source has been an integral part of locals’ lives. It used to be clean and suitable for human activities, now parts of it are murky, making it unfit for consumption and swimming.
Pollution concerns aside, the Orinoco is also home to the famous, toothy piranhas. While an excited tourist may want to swim to get clean, these fishes might clean them out! But seriously, the tainted water is the issue and not the often maligned fish.
