People use soil in many ways. Soil provides nutrients for growing crops to feed the world's population, but human activities like farming, mining, and deforestation have significantly impacted the earth. When trees and plants are removed, soil erodes more quickly than it can replenish. Farming the same lands for many years also depletes nutrients in the soil. However, practices like contour plowing, strip cropping, and replanting vegetation help conserve soil and protect it from erosion. Without careful management of this important resource, soil degradation poses a major threat.

3. Is important to take care about the resources of soil because throughout human history, soil has been repeatedly ruined and destroyed. This is highly dangerous to a civilization, because soil is an essential resource that is useful in many ways. Introduction

4. Prior knowledge Prior knowledge Is important because there the seeds of the plants grow there in the soil. The soil is important also because it helps us to cultivate our food

6. HUMAN IMPACT ON EARTH By Patti Hutchison Land, water, air. Our lives depend upon them. The Earth has generously given us these resources for millions of years. Since humans evolved, our population has grown rapidly. We have used and abused our Earth. Humans have had a serious impact on the land. We use it to grow crops to feed our growing population. We also use it to provide energy. One of the largest impacts humans have had on the earth is the mining of mineral resources. Almost everything we use is made of metals and other land resources. We use copper to make wires that carry our electricity. We use sand and gravel to pave our roads, and on having exploited these resources we are finishing with the land. Farming disrupts the natural ecosystems that exist on earth. Chemicals are used to kill pests such as insects and weeds. These chemicals can harm plants and animals that are good for the environment.

7. HOW DO PEOPLE USE SOIL RESOURCES? Resources from the Land By: Patti Hutchison Land provides a place for humans and animals to live. It also provides places to grow crops, trees, and grasslands. These are important resources for living things. What other natural resources do we get from the land? Let's start from the top. At the surface of the land is topsoil. Topsoil contains minerals and nutrients that plants need to grow. Rich topsoil is used by farmers to produce food for us to eat. It can take up to 1000 years to form a few inches of topsoil. But those few inches can be lost in a matter of minutes. Without plant cover, topsoil can be eroded by wind or water very quickly. The Earth loses much of its topsoil each year. It is eroded faster than it can be replaced. The result is drier and less fertile soil. In some areas, erosion is causing desertification. Soil is needed to feed a growing population. Many areas have plans to help conserve the soil we depend on for so much.
