Water is something that humans need to survive. Without it, we, and most of the animal kingdom, would die. A human’s body is made up of water so it is necessary to make sure we consume a substantial amount every day. With the population constantly rising, concerns about whether or not there is enough water left to support us are growing. So, how much fresh water is actually left on planet Earth?
With Earth being made up of 70% water, you would think that there would be an endless amount for us to drink. However, this is not the case. Even though the earth is more water than not, only 2.5% of water is drinkable.
Most of the water on earth is saline or ocean based, limiting the amount we can actually drink. Out of the 2.5% of fresh water we can consume, just 1% is easily accessible to humans. This is due to the fact that the other 1.5% is trapped in glaciers and snowfields.
There is no denying that there is a water crisis on earth. With the population rising and the fact that some people and societies seem to excessively waste our precious resource, we can only hope that it is a source that will not run dry.
If the water runs dry then there will be serious repercussions. We will struggle to grow food, and widespread famine will hit the planet. Without fresh water, the public will be forced to drink from dirty water sources, which will lead to the rapid spread of water borne diseases like typhoid. As well as this, nations would be fighting for what remains of this valuable source, possibly creating further armed conflicts.
There are two solutions to solving the water crisis. First, we can learn how to turn salt water into fresh water. This is called Desalination. At the moment this is possible, but it is something that is very expensive to carry out and would be difficult to do on a large scale. The second solution is improving our ability to turn dirty water into clean water. Scientists currently have different technologies to do this, and they believe that this is a way of helping stop the growth of the water crisis.
Only 1% of the water on earth is currently available for humans to consume. With the way things are going, there could potentially be less if the water crisis continues. Until technology advances to be able to convert the salt water of our oceans into fresh water, and turn dirty water into clean water on a widespread scale, we will only have access to a very small percentage of our planet’s water.
