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?
