Agriculture is probably the most important economic factor in human life. It maintains a steady source for the food products that we eat, as well as promote a source of livelihood and earning opportunity for communities worldwide. Agriculture courses teach us the essential principles on how to grow the plant and animal products that we need, including proper maintenance of the various natural resources that support growth and production. Various resources on agriculture are available on the internet that can assist you on the proper way of doing things. But this is not the only important aspect of learning agriculture online study. Agriculture also teaches you how to address future problems that may be encountered through agricultural pollution.
One of the greatest environmental and health threats to our water supply is agricultural pollution. Practicing organic farming or applying the principles of sustainable agriculture may give solutions to pesticide, herbicide and fertilizer use; however, without proper care and implementation of irrigation and farm management, natural occurrences brought about by rain and storms can pose as problems. One of these is commonly known as agricultural runoff. The process involves water being allowed to flow back to the water reservoirs that are contaminated by minerals, nitrates and bacteria. Animal manure that are often used in green farming may be essential in keeping the soil fertile, but may also carry pathogens and bacteria that are harmful to human health. When farmers use chemical pesticides and fertilizers, the harmful effects are obvious. But, do you know that chicken manure may be full of copper nitrate that may be as dangerous? If not addressed, these harmful substances may go into groundwater and contaminate drinking water supplies.
Agriculture science courses promote the use of proper farm and soil management. Farmers and landowners can control agricultural runoff to a certain extent that it will not reach and pollute the water sources. However, heavy rains, flash floods and other weather disturbances are not controllable factors. If the unsuspecting farmer uses contaminated water to irrigate the crops, it will bring undue harm not only to the people who will consume the produce but also the animals that depend on them as their natural food. Science would need to discover new ways of enhancing the growth and production of food crops without the use of traditional fertilizers and pesticides that can cause water pollution and pose future health problems. Agriculture courses and help sustain the environment and food supply.
