Could the earth run out of earth? It doesn’t seem possible, but it takes thousands of years for soil to develop. This means that soil is practically a nonrenewable resource. Meanwhile, soil is being worn out by farming, polluted by chemicals, and eroded by wind and water.
If this concerns you, you’re not alone. Some agricultural engineers come up with farming practices that use soil more efficiently. Others help farmers by designing power systems, tools, and storage space. Still others look for ways to ensure food safety during processing. Thanks to agricultural engineering, farmers are getting better at producing safe food more efficiently while protecting the environment and using natural resources wisely.
