Soils by Cailtin



Soils are complex mixtures of minerals, organic matter, water, air. Not only is it home thousands of microorganisms, but it is also an incredibly important resource for humans. It plays a key role in maintaining food production and keeping a clean underground water supply. Just remember to not get confused between soil and dirt. There is a drastic difference between the two.
Unfortunately, poor land management practices such as overgrazing, deforestation, and over cultivation have led to serious soil degradation problems. If these problems continue, starvation and water shortage will be prevalent throughout the world.


Interesting Facts:
       There are 70,000 different types of soil found in the United States.
       1 tablespoon of soil has more organisms living in it than there are people living on Earth.
       15 tons of dry soil pass through an earthworm each year.
       10% of the world's carbon emissions are stored in soil.

Questions:
       How can we protect soil, so that it can continue to be a valuable resource for us?

       How would our lives change if we got rid of soil?
