How much water is in the world and how much can we use?
Lets talk about this ;
The total amount of water in the world is estimated to be about 1.386 billion cubic kilometers (km³) or 332.5 million cubic miles (mi³), of which about 97.5% is saltwater in the oceans and seas, and only about 2.5% is freshwater. However, much of this freshwater is trapped in glaciers and ice caps, groundwater, or is located in inaccessible places, so only a small fraction of the total water on Earth is available for human use.
The amount of water that can be used by humans depends on several factors, including the location, climate, population, and available water resources. According to the United Nations, the global annual renewable freshwater supply is around 42,000 km³, but due to various factors such as pollution, over-extraction, and climate change, the amount of water that can be sustainably used by humans is much lower.
In summary, while there is a vast amount of water on Earth, only a small fraction is accessible and available for human use, and the amount that can be sustainably used depends on various factors and varies from location to location.
