Answer:
Humans and other organisms cannot survive without fresh water. If there is no fresh water, humans will have to desalinate the seawater that is quite expensive. Without freshwater, all other organisms such as animals and birds will die after drinking salinated water. Furthermore, if we irrigate our lands with salted water, there will be no crops and humans will face scarcity of food.

- Hence the life cannot have started without the presence of freshwater as the earth was formed 4.5 billion years ago the life forms first originated in the shallow hydrothermal vents that show us the bacterial forms that used oxygenated water.
- With the advancement of geologic time, the freshwater resources become scarce and thus the resultant freshwater stated to get depleted fast with the rising temperatures.
- If freshwater did not exist human population would not have survived as we would be unable to meet our daily needs of food and the drinking water drinking saline and contaminated water would make us sick and even cause death.
