      My Name is Maria Camila Ambuila Chara i have 12 years old i am in 5th grade in bennett school. My favorite animal is dog and my favorite food are pizza. I like to swim and go to cine wite my friends. I am duing this project because is important to know and to announce as the persons the natural resources use
    • 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.
    • 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

    • 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.
      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.
    • Good use of soil
      • The farmers need to be careful when plowing the land.
      • The extraction of resources minerals tame a toll on the earth.
      • When are moved large amounts of soil and rock, the landscape is completely changed.
      • When the ecosystems are disturbed.
      • The Substances chemicals are used to kill pests and insects harm the plants and animal and the enviroment.
    • Bad use of soil
      Farmingon the same land for many years can also be harmful to the soil. The plants will use all the minerals in the soil. Year after year the minerals are less and less for new plants that are put on the land.
      Another way farmers save the soil is to strip crop ping is planting strips of thick grass or clover between strips of crops. The thick mat helps keep water in the soil and from washing it away.
      Some farmers also use contour plowing. Contour plowing is planting rows of crops around the sides of hills instead of up and down, this way water does not run off in straight lines and the soil isn’t washed away.
      Growing the same type of crop on the same land for many years removes minerals. When people remove plants and tree, soil may be washed away. Farmers conserve soil by strip cropping, contour plowing, and other methods.

      The farming of lands in places that do not have earring to diminish the depletion of the fertile soil
      The erosion of the soil
      Not to fell vegetation to prevent the fertile cap of the soil from being exposed to the rain and to the Sun and the bark of the soil hardens and dries off.
      The deforestation y pollution with pesticides, fertilizers and herbicides
      The buildings are not constructed on fertile soil but in urban zones
      Urbanization and new buildings on fertile soil
