Agroforestry could take this further, growing a variety of plants together in ways that their biological systems support each other and help soil to flourish. Intensive farming, especially monoculture, is damaging the very soil it needs to grow healthy crops. desertification: Conversion and degradation of land which previously supported to plant growth, in arid or semi-arid regions, to desert land. Prentice Hall, 2002. Indeed, soil quality is directly linked to food quality and quantity. This cycling helps to maintain the essential nutrients required for plant growth in the soil. Soil, Agriculture, and Agricultural Biotechnology, Earth's Climate: Past, Present, and Future. Monoculture farming, where one crop is grown repeatedly on the same ground, drains the soil of specific nutrients and allows pests, pathogens, and diseases to thrive. The benefits of development need to be weighed against the harm to animals that may be forced to find new habitats, the depletion of resources we may want in the future (such as water or timber), or damage to resources we use today.Development and conservation can coexist in harmony. Healthy soils conduct the Earths energy, which is important for life. The distribution of these soil components in a particular soil is influenced by the five factors of soil formation: parent material, time, climate, organisms, and topography (Jenny 1941).
