Quarrying is the process of extracting valuable rocks from the ground. The opencast techniques employed leave deep holes in the ground. Open quarries pose a threat to the environment. Below are the effects of quarrying that have made companies campaign against it.

Ecological Imbalance

Quarrying interferes with the biodiversity of a place. Microorganisms get killed during the excavation process. Cutting of trees and other plants occurs in preparation for quarrying. In the process, there will be a loss in the rare tree species.

Loss of the Landscapes Beautiful Scenery

The land will lose its aesthetic value. Open holes everywhere on the ground do not offer the best sites. The once green ground covered with grass is left bare.

Noise Pollution

The bulldozers and drills used cause disturbing sounds dangerous to the human ear. During transportation of the excavated stones, unpleasant noises are also produced. This causes irritation, headaches and high blood pressure among residents. Continuous exposure may lead to deafness.

Air and Water Pollution

Dust particles disperse in the air during blasting. The amount of dust carried to the surrounding area depends on the dust particle sizes and wind speed. Its effects include stomata blockage in plants and eye irritations. It may also change the soil properties upon settling on the ground.

Land Dereliction

After quarrying, the land left behind will not support plant growth. It HAS lost its fertility. Quarrying kills the small organisms in charge of aeration of the soil.it also gets rid of humus.


Erosion is the carrying away of loose soil particles by wind, ice or moving water. Quarrying leaves the ground with no cover. The loose topsoil is carried away, farther reducing its value.

Quarrying has more adverse effects than you can imagine. It also interferes with the hydrological cycle. This is the reason why it has met objection from many companies.
