Wendell Berry's essay

After reading the “The Unsettling of America Culture and Agriculture”, I could think again the fact that humans can not create energy and all energy comes from the earth. Berry stated the difference between humans energy in our body and the energy that is made by humans. Our body can be recycled when we use energy, but the energy which is produced by humans can not be recycled. He emphasized the importance of soil for human and the earth. All energy supplies and resources come from the soil to meet for us, so we really need to protect soil of the earth because it is one of the important circles of our life; healthy soil makes healthy humans.
