The market system and modern agriculture
Modern agriculture, through its total dependence on the market, has turned into a business than a vocation.
Changed the eating habits of people and a market that is abuzz with foreign –made mouth –watering dishes has totally cut into he traditional market of agricultural goods. Thus, today, agriculture has been reduced to total dependence on market tastes and is guided by the demand factor. What to produce is decided not by nature, But by the market! In other words, the choice of what to grow is no longer with the farmer nor is it guided by the national forces like rain and/ or soil. Today, it is being forced by the market.
New farming methods such as buying of seeds from the market and not saving them from the last crop have also had deleterious effect on the agricultural practices. Study the effects of the changing practices on farming, farm produce and the role of market in the choice of crop by farmers.

When acid rain reaches the earth, it acidifies the land turning it barren. It affects living farms. Amphibians like frogs lay eggs in small holes in the ground. If acid rains reach there the eggs do not hatch. In the same way, moll scans and corals depend on calcium for their existence. Acid rain destroys calcium. Fish and other aquatic animals cannot survive in acid rain. Acid rain destroys the food chain, forests and crops are ruined. Quality of both surface and ground water is affected.
