Water isn't just essential for all life on earth, it's also the key medium in wetland ecosystems. South America's Paranal, the largest wet prairie, is home to giants like the jaguar, capibara, otter and cayman, yet none could survive without the waste recycling sludge on the river beds. The largest population of Bengal tiger lives in the Sundarbans mangrove forest, hunting deer and monkeys, none of which would survive without the crabs whose mud digging helps the trees survive. Coral reefs, like the Maldives, depend on symbiosis between algae and sponges. In the cold oceans, massive krill and algae are crucial for the food cycle and even CO2 absorption, while the weather there steers climate cycles all over the planet.
