A quarry is a wide and deep hole which forms when people and machines remove materials from the earth’s crust. Quarrying is the act of removing material from the earth. Machines or simple equipment remove the material from the crust. Quarries have negative effects on the physical and human environment.

Loss of Biodiversity

People clear vegetation to create space at the quarrying site. Clearing vegetation destroys the habitats of living organisms. Animals and insects either flee or die. After destruction of vegetation, an ecosystem takes centuries to recover. Therefore, some of the natural biodiversity may never regenerate.

Pollution

The noise from machines creates a disturbance. It disrupts neighborhood routines. Machines emit Carbon dioxide, a greenhouse gas which depletes the Ozone layer. Depletion of the Ozone layer exposes living things to harmful ultraviolet rays. Quarrying kicks up a lot of dust and debris. These pollute the air. The dust attaches to moisture drops in the atmosphere. Both dust and carbon dioxide attach to moisture drops in the atmosphere and form smog. Smog is a cloud that blocks the sun’s rays from reaching the ground. Lack of sunlight threatens life on earth. It causes a rise in global temperature and blocks terrestrial radiation, raising temperatures.

Dereliction

Quarrying destroys the productive land. Quarrying sites have huge gaping holes, which remain open after the quarrying ends. Whenever it rains, the holes fill with water. The stagnant water is a habitat for disease-causing insect vectors like mosquitoes. Animals and people fall into the pools and drown. Destruction of vegetation leads to soil erosion. Water, ice and wind erode the top soil after clearance of vegetation. The land becomes unproductive. It is possible to rehabilitate derelict land, but the cost of rehabilitation is very high.

Quarries destroy earth’s aesthetic value and disrupt ecosystems. Their demerits outweigh their usefulness. Individuals should ban quarrying to avoid further environmental destruction.
