Agriculture industries
is the cultivation of animals, plants, fungi, and other life forms for food, fiber, biofuel, medicinals and other products used to sustain and enhance human life.Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization. The study of agriculture is known as agricultural science. The history of agriculture dates back thousands of years, and its development has been driven and defined by greatly different climates, cultures, and technologies. However, all farming generally relies on techniques to expand and maintain the lands that are suitable for raising domesticated species. For plants, this usually requires some form of irrigation, although there are methods of dryland farming. Livestock are raised in a combination of grassland-based and landless systems, in an industry that covers almost one-third of the world's ice- and water-free area. In the developed world, industrial agriculture based on large-scale monoculture has become the dominant system of modern farming, although there is growing support for sustainable agriculture, including permaculture and organic agriculture.

Fishing industries
Fishing is the activity of trying to catch fish. Fishing usually takes place in the wild. Techniques for catching fish include hand gathering, spearing, netting, angling and trapping.
The term fishing may be applied to catching other aquatic animals such as molluscs, cephalopods, crustaceans, andechinoderms. The term is not normally applied to catching farmed fish, or to aquatic mammals, such as whales, where the term whaling is more appropriate.
According to FAO statistics, the total number of commercial fishermen and fish farmers is estimated to be 38 million.Fisheries and aquaculture provide direct and indirect employment to over 500 million people in developing countries.In 2005, the worldwide per capita consumption of fish captured from wild fisheries was 14.4 kilograms, with an additional 7.4 kilograms harvested from fish farms.In addition to providing food, modern fishing is also a recreational pastime.
