Potable water.

Potable water or rather, drinkable water as we know it comes from a lot of different sources.
But first let's see where ALL the water comes from

Here is a list of water sources:

  • - Oceans 97.2%
  • - Ice Caps/Glaciers 2.0%
  • - Groundwater 0.62%
  • - Freshwater Lakes 0.009%
  • - Inland Seas/Salt Lakes 0.008%
  • - Atmosphere 0.001%
  • - Rivers 0.0001%

  • As we can see, water in rivers is the least common on Earth. Used to be a higher percentage, but because of our high pollution output, this has changed drastically

The United States Geological Survey provides a visual illustration (represented in spheres) as to the amount of available water in comparison to the size of the earth.

The largest sphere represents all of the water on earth (oceans, ice caps, lakes, rivers, groundwater) and has a volume of 332,500,000 cubic miles.

The second-largest sphere, with a volume of 2,551,100 cubic miles, represents the earth’s freshwater supply in liquid form.  99% of the liquid freshwater is groundwater, much of which is far too deep to be accessible.

The remainder of the earth’s freshwater exists in lakes and rivers,
represented by the tiniest sphere, with a volume of 22,339 cubic miles (Perlman, 2016).

    I think that your topic is very impactful. There is not enough water to go around; hints the droughts. I enjoy that you provide the pictures which make it easy to tell the difference between the earth to water. I think that we should have more information on this topic as it can be very important not just now but also in the near future.

    I didn’t not know that we don’t have that much water. I thought we had a lot more to go around for everyone. The picture you provide was a great way to show of much water we have on our earth that we can drink.

    Excellent post on your bolg, great information organization. I found the way you showed the list of forms of water sources very interesting, some of them I didn't know had such a "small" percentage. It is very interesting and at the same time distressing to see the size of our planet and to see that the amount of water available is very small compared to the size of the earth.

On Shaky Ground

By: Hannah Meadows The New Madrid fault line is a growing danger right under peoples feet. Most people don’t realize how catastrophic it would be if the fault line went off and the worst part… there is no telling when it will go off. Usually, earthquakes wouldn’t be an issue in places like California because all of their buildings are built to withstand earthquakes. However, the New Madrid fault line sits right along southern Missouri and Missouri is known for its sedimentary rock. This means an earthquake in Missouri would cause all buildings and houses to be buried since they aren’t built to withstand earthquakes. Now what would the statistics really look like if the New Madrid fault line were to go off unexpectedly?  84,000 buildings damaged and 37,000 more destroyed, almost entirely residences  Over 15,000 people killed and an additional 120,000 displaced Nearly 200 schools and over 100 fire stations would be damaged  37 hospitals and 67 police stations would be compl...

Energy: Hydropower Pros and Cons

Image
 Hydropower is not often talked about as a primary option for sustainable energy, however, 6.6% of energy produced in the U.S. is through hydropower, compared to solar energy which happens to only be 2.3% and is usually the first thought when someone mentions “clean energy.” The reason for this being the majority hydropower plants only give energy to large-scale, industrial operations.  Hydropower boasts a few positives that make it a viable option, those being that it is reliable, safe, and produces a very low amount of emissions. Other than that, they are fairly expensive to build, and they have a very realistic potential to cause droughts. Hydropower is an interesting source of energy and as of now it is only really used for industrial use, however in the future there is a very real possibility for it to be used to power residential areas.  https://www.solarreviews.com/blog/hydroelectric-energy-pros-and-cons#pros-and-cons

They called it a shrinking world because our technology is getting even better and better. Anyways going into the article there is a graph and a description of the burgeoning population of the globe. After it talk about this problem it gets into how this can help our food problem and how we are on our way to a new type of farming. It ends off with them giving numbers on there work with BI intelligence and how much money they made in 2020 and what they are projected to make in 2050.
