Final answer:
After Fisher and Venus start looking for clean water, they may encounter various methods of obtaining clean water, such as a water purification system.
The availability of clean water depends on the resources and infrastructure in each region.
Different planets, like Venus, Earth, and Mars, may have started with a significant supply of water, but its distribution may have varied due to geological processes and atmospheric conditions.
Step-by-step explanation:
After Fisher and Venus start looking for clean water, they may encounter various methods of obtaining clean water. One method mentioned is the use of a water purification system. This system, developed by NASA, uses chemical adsorption, ion exchange, and ultra-filtration processes to turn wastewater into drinkable water.
In addition, people in wealthier nations have access to clean running water in their homes, while in poorer nations, people have to get water where they can. Therefore, the availability of clean water depends on the resources and infrastructure in each region.
It is also important to note that different planets, like Venus, Earth, and Mars, may have started with a significant supply of water. However, the water distribution on each planet may have varied due to geological processes and atmospheric conditions.
