Save the Soils
Poor soil means weak plants. That could lead to a lot of oxygen-starved, hungry humans. There are many ways to keep soil from eroding away: contour plowing, strip cropping, terracing, planting windbreaks. Which way is best? Do a little research, and then tell the world your choice. Write a newspaper editorial telling which conservation method you think is best and why. Save that soil!
