The negative externality behind the production of bricks

As there are more and more buildings constructed, the demand of bricks increases, which leads to the rise in production of bricks in many countries. Bricks are commonly produced near industrial areas where construction is highly developed. A brick can be composed of clay-bearing soil, sand, and lime, or concrete materials. The primary steps of manufacturing bricks are preparing ingredients needed for making bricks, molding those materials into the shape of bricks, drying bricks and finally burning them. Because bricks are made for building, construction companies are the main consumers.

However, the large scale of burning fuels such as coal, oil, gas to produce bricks is responsible for environmental pollution that has a direct influence on agricultural crops and plantations. In fact, brick kilns emit toxic fumes containing suspended particulate matters rich in carbon particles and high concentration of carbon monoxides and oxides of sulfur that are harmful to the health of plants. Also, fog and acid rain resulting from air pollution cause extensive damages to plant life. Because the manufacturing of bricks causes air pollution as a side effect that hampers the growth of crops, local farmers are adversely impacted. This loss of income in agriculture will be the negative externality of brickmaking operation.
