Main topic Agriculture
Agriculture or farming is culture of plants and animals for production of food, fiber, fuel, raw materials and other products necessary for human beings. Agriculture includes animal husbandry, aquaculture, apiculture and poultry farming. Agriculture employs 33% of the world's workers. Many production practices have evolved for improving production like tillage, pest control, nutrient management and water management.
For getting proper remuneration for the farmer the produce has to be processed, transported, stored and marketed. To maximize yields selective breeding, bio-technology, genetics and genetic engineering have a major role. Genetically modified crops are being produced with disease-resistance and other desirable qualities.
However agriculture has many negative impacts on the environment. The livestock contribute to green-house gases, especially methane. Farm and animal waste and manure contribute the green house gas, nitric oxide. Agricultural activities like tillage release carbon into atmosphere. Now the emphasis is on environment friendly agriculture practices which can sustain environmentally and economically.
