Industrialization, in any society, is a major initiator of development and urbanization. Although the merits of industrialization are innumerable, it has been identified as a major threat to the environment as it releases various toxic chemicals, gases, solid wastes as well as microbes of various kinds into our immediate environment—land, air, and water.

How Industrial Agriculture Affects Our Water

When many of us think of pollution, images of smoggy cities and litter-infested oceans come to mind. While littering and gasoline-fueled cars are a major contributor to pollution, there are many other influences that are important to be aware of. Essentially, pollution occurs when substances are introduced to the environment that have harmful effects, damaging the quality of land, water, and air. The cause is the accumulation of solid and liquid waste materials that contaminate groundwater and soil. These waste materials are often referred to as municipal solid waste MSW , which includes both hazardous and non-hazardous waste. When waste is deposited onto an area of land, the permeability of the soil formations below the waste can increase or reduce the risk of land pollution. The higher the permeability of the soil, the more likely that land pollution will occur.
