Introduction

Food Production. This essay will explain about farming today, and how it affects our environment, also ways in which we can help to protect our environment, our health and animal welfare. Farming is the production of food and other materials by raising plants and animals. Many people buy their food in supermarkets close to their homes, but the food is imported from many different countries, and many products are farmed in a number of different ways. The way food is farmed affects the environment. It also affects people's health and the treatment of animals. Some farming methods are more harmful than others. Over 11,000 years ago, people got all their food by gathering wild plants, hunting and also from fishing. They travelled around constantly in search for food. But then people learned how to grow plants from seeds. They learned how to raise animals, and then began to settle in one place. ...read more.

As the number of people grows daily, more food is needed and more land is being utilised for farming, decreasing the amount of land used by animals and plants, especially in the case of rainforests in tropical countries. As the rainforest are destroyed 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 include: 1) The hybridisation of plant species 2) improvements from animal breeding 3) the use of fertilisers and insecticides There are two types of insecticide found: 1) Organic: from plants and animals, e.g. manure and compost 2) inorganic: from non-living materials, e.g. rocks, minerals (these can disrupt ecosystems) When inorganic fertilisers are dissolved 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. ...read more.

Conclusion

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 know what effects food production has on our environment, so how can we prevent 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 farming is the raising of animals without hormones, antibiotics or other artificial chemicals; it also includes using organic feed and allowing animals sufficient range of movement and sunlight. Genetic engineering of plants and animals is not considered organic. Organic farming is definitely a way forward. Lets hope in the future more people see it this way.
