Happy World Water Day! Whether human or animal, water is essential to life. And while the Earth is comprised of 70% water, only around 3% is freshwater, with more than 100,000 species relying on freshwater ecosystems to survive, according to world_wildlife. One of those animals is the Amazon river dolphin, whose population has diminished as a result of rising pollution and human encroachment. . . . . . #worldwaterday #waterday #freshwater #earth #amazonriverdolphin #riverdolphin #animalplanet #animal #discovery #videooftheday"
