The "otterly" amazing connection
Otters are intelligent, playful animals. There are thirteen official varieties, for example, the giant river otter, the North American river otter, and the European otter. They live on both land and water but are tremendous anglers, so they spend much of their time in the water. The North American river otter reaches speeds of almost 7mph while swimming. For comparison, the fastest human swimmer has barely cracked 5mph.
But there’s a catch: river otters only survive in clean water. The presence of river otters indicates a healthy environment.
Humans are similar in that we require comparatively pristine water. Contaminated water is linked to the transmission of diseases such as cholera, dysentery, typhoid, and polio. These diseases often carry a life sentence.
