Importance of soil

If there wasn't soil today we wouldn't be alive. If there wasn't soil today we would have no food. We need trees to breathe and if thee wasn't any soil we wouldn't be able to breathe.

Misuses of soils

Some misuses of soil is farming if there is a big drought and you have turned your soil and a day is really windy you soil could just go away like dust. Another is littering we could help by picking up the trash.

When your in the fields of agronomy you will be studying the soil and the food you grow. You will try to find better ways to make the soil or food better like putting them in shoes or the ground and see which one grows better.
