Although there are many practices already in place that will decrease the pollution, increase productivity, and save farmers money in the long run, the farmers are careful to change practices. Sedimentation The most prevalent source of agricultural water pollution is soil that is washed off of fields. These fields have been treated with fertilizers and pesticides, which over time have accumulated heavy metals that are then transferred to lakes and streams. The excess particles cloud the water blocking vital oxygen and sun for the aquatic plants. Nutrients Farmers apply nutrients such as nitrogen, phosphorus, manure, and potassium in the form of fertilizers to produce a better product for the consumers.
Many consumers and farmers have discovered that living in an industrialized culture where the focus has become faster, bigger, and cheaper is not the best way to produce our food. Obsessed with productivity, the agriculture industry is reaping the negative consequences of creating an unsustainable environment for food production. Time and time again, the media captures stories regarding deadly bacterial contamination and dangerous pesticide contamination causing illness and death in our communities. The environment is also damaged and contaminated. This devastating trend, due to irresponsible farming practices as a result of the industrialization of the food industry, has become all too common.
Soil contains various metals and living organisms. All the food, which humans use, are produced on soil. Soil also serves as a habitat for some living things. Because of these important roles played by soil, damages to the soil will result in crippling effects to food supply production leading to possible food shortage, and rising food costs. The trends of the major soil degradation are almost difficult to measure because they are constantly changing.
The ecosystem of nutrients in the soil is very fragile and if farmers are not careful they will harm the ecosystem, which will cause farmers to loose yields and the world to loose its resources. Nutrient management is important to the future of agriculture because responsible nutrient management helps produce more crops to support the world. There are many factors that go into proper nutrient management. Fertilizers Fertilizers are at the forefront of nutrient management because they affect the plants ability to grow and produce seeds. Fertilizers are defined as a chemical or natural substance added to soil to increase the fertility.
Both affect each other in many ways. For example, continues use of fertilizers currently causes of greenhouse emissions. This environmental problem can affect the agricultural field, because high concentration of carbon dioxide cause the leaf pore shrink and diminishing tree cooling power, this will resulting in decreasing crop production and at the same time global warming phenomenon. Besides, agriculture also has both harmful and beneficial effects on the environment by changing the quality and quantity of soil, water, air, biodiversity and landscapes. Farming is currently a main source of water pollution.
Topsoil depletion, groundwater contamination, the decline of family farms, continued neglect of the living and working conditions for farm labourers, increasing costs of production, and the disintegration of economic and social conditions in rural communities. These are the cons of the new improved agriculture. Environmental impacts have increased, including potential ruin of the soil and water resources essential to both farm productivity and human health. Agriculture also leads to soil erosion, both through rainfall and wind. This soil can damage the aquatic ecosystems it ends up in, an... ... middle of paper ... ...e sun, this is of a longer wavelength and is absorbed by the atmosphere.
First, genetically modified foods should be encouraged because the use of GMOs promotes positive farming and agricultural practices that have less of an impact on the environment than traditional farming. While necessary to our modern society, farming unquestionably harms the environment in a variety of ways. Plowing depletes the soil of valuable nutrients and can lead to increased erosion and pollution. Since the beginning of the agricultural revolution, farmers have plowed their land, often several times a year for weed control, but “with plowing has come runoff that pollutes rivers and blights aquatic habitat, erosion that wears away the land, and the release into the atmosphere of greenhouse gases stored in the soil” (Rauch 371). Herbicides are another method of weed control, which also can be very harmful to the environment by polluting waterways with toxic chemicals.
Factory farming also has a negative impact on the environment. The waste run-off of fertilizing manure spoils habitats and water sources, and methane from cattle is increasing the effects of greenhouse gases in our climate. Increasing the free-range farming industry, creating government legislation, and regulating animal production could resolve this problem in our food industry. In addition, providing more accessible knowledge and information for the public to be aware of where our food is coming from can also be beneficial. Factory farms may be a solution to the high demand of animal products, but they are bad for society, ... ... middle of paper ... ...oi.org/10.1289/ehp.121-a182 [online 01 June 2013] Nordgren, Anders.
To improve efficiency hedges have been removed and this has reduced the amount of habitat available for wildlife. It has also increased soil erosion. The removal of hedges increases the area of land available for crops, destroys the habitat of predators and keeps the number of pests down. Monocultures are susceptible to pests and large amounts of pesticide have to be used. Farm animals can produce large quantities of organic effluent.
Erosion affects productivity because it removes the surface soils, containing most of the organic matter, plant nutrients, and fine soil particles, which help to retain water and nutrients in the root zone where they are available to plants. The subsoils that remain tend to be less fertile, less absorbent, and less able to retain pesticides, fertilizers, and other plant nutrients. Why then is erosion allowed to ... ... middle of paper ... ... of the many potential problems caused by the heavy use of chemicals in modern agriculture. This, combined with the rapid rise in the cost of fertilizers and pesticides, has led many farmers to seek ways of reducing their reliance on chemical- intensive methods of farming. A small but growing percentage of farmers are farming with no synthetic chemicals, and many others are reducing their overall chemical use.
