Food Production

This essay will explain about country today, and how it affects our environment, also ways in which we can help to protect our environment, our health and animal welf atomic number 18.Farming is the production of regimen and former(a) materials by altitude plants and animals. Many masses buy their food in supermarkets close to their homes, exclusively the food is imported from more different countries, and many products argon farmed in a number of different ways. The way food is farmed affects the environment. It also affects peoples health and the tr fertilizement of animals. Some nation methods are more harmful than others. everyplace 11,000 years ago, people got altogether their food by gathering undue plants, hunting and also from fishing. They travelled around constantly in expect for food. save then people learned how to grow plants from seeds. They learned how to farm animals, and then began to settle in one place. Now they could wait for their plants and crops to grow, and beat to harvest them when they were ripe.Then about 250 years ago farmers in oft wealthier countries started utilise machines. Machinery did most of the work for people, so people could mother food for many more people and sell it to their community. Scientists then developed chemicals to recrudesce more food, and developed new plants and different breeds of animals. Many more farmers without delay use more chemicals such as fertilisers, pesticides and herbicides to grow more crops. Fertilisers make the mark more fertile. Pesticides kill insects that harm crops and herbicides kill weeds among the crops. right away in wealthy countries such as Britain and the USA people equal in cities rely on fewer farmers in the countryside to grow their food. tho many people are worried about how their food is produced, chemicals are sprayed onto the crops and they can stay on the food. They can also run into rivers and the water system underground. New kinds of plants and ne w breads of animals may upset the natural environment. Valuable soil is also be lost or damaged. at that place is a stack of reduction in land and one of the causes for this is farming Farming methods, including overgrazing, inconclusive farming methods and the overstocking of land, remove essential nutrients from the soil.This results in the denudation of the land. As no vegetation is available to retain the soil, it is washed away. Soil erosion except lessens the amount of land available for natural plants and animals. As the number of people grows daily, more food is needed and more land is being utilized for farming, decreasing the amount of land apply by animals and plants, especially in the case of rainfo tole fannyes in tropical countries. As the rainforest are undone to make way for more farming land. Nature, insect and vegetation. In other countries hedge rows and trees are lost also killing that which resides there.Modern farming results include1) The hybridisation of plant species2) improvements from animal breeding3) the use of fertilisers and insecticidesThere are two types of insecticide found1) Organic from plants and animals, e.g. manure and convert2) inorganic from non-living materials, e.g. rocks, minerals (these can disrupt ecosystems)When inorganic fertilisers are turn in rainwater, they run off into water sources. This is called Eutrophication. Eutrophication is the over growth of algae in water ecosystems where nutrients are usually limiting. Many fresh water systems are oligotrophic, meaning that the growth of primary producers (algae) is limited non by dissolved gas or light, but by nutrients such as nitrates and minerals. The organisms in these environments have evolved to be optimally suited to these conditions, and everything works fairly well.But when someone configurations something next to a lake (e.g. golf course), and the fertilizer being apply on the grass runs off into the lake, the algae grows too fast for the re st of the ecosystem to keep up, and overgrows the lake, killing everything in it. Thats one example, there are many other the solutions more often than not involve not washing lots of nutrients into lakes and streams (or the ocean, which, although generally full of nutrients, can also be locally overwhelmed with runoff, especially in coral reef environments).Farmers use pesticides and insecticides to kill organisms that damage their crops.The following methods are used1) Chemical a poison is introduced, e.g. herbicides and dichlorodiphenyltrichloroethane2) biological a natural predator is introduced, e.g. snakes to kill rats3) mechanical people and machines are used, e.g. rat trapsSide effects of these methods can include1) The death of animals that are not pests2) DDT entering and moving up the food chainDDT is an effective but dangerous pesticide. Below is a diagram to turn out how DDT is moved up the food chain.Farming produces much pollution, generally water pollution through chemicals, and air pollution through machinery used in the farming process, the consequences of fumes being given off accept to, the green house effect which leads to global warming. Detrimental effects on human health and vegetation. This also causes acid rain. Water pollution was mentioned earlier. And how the chemicals being used travel through the lakes and rivers. This disrupts our ecosystems. So now you basically fill in what effects food production has on our environment, so how can we observe this from happening? Well for a start we could all begin to eat more organic foods. Organic agriculture bars the use of synthetic pesticides and artificial fertilizers, and instead relies on ecological interactions to raise yields, reduce pests and build soil fertility.Diverse planting patterns, frequent rotations and attraction of beneficial insects, for instance, would all be organic means of pest control. Organic meat and dairy farm farming is the raising of animals without horm ones, antibiotics or other artificial chemicals it also includes using organic feed and allowing animals sufficient range of movement and sunlight. Genetic engineer of plants and animals is not considered organic. Organic farming is definitely a way forward. Lets promise in the future more people see it this way.
