Answer»

Ecosystem: An Ecosystem is a complex set of relationship among the living resources habitats and residents of an area but changing global pattern of land use have had a significant negative effect on ecosystem.

There is a biotic balance in an ecosystem, which makes it possible to sustain the various interdependent members (plant and animal life). Ecosystem maintains a very delicate balance. Various human activities have been done to disrupt this balance and destroy the world’s ecosystems.

Adverse effect of mining on ecosystem:

1. It causes deforestation and removal of vegetation. In order to construct a mine large amount of land has to be cleared off trees and vegetation. This is bad for environment. 

2. The waste material remaining after the valuable minerals have been extracted is called tailing. These tailings are generally made up of hazardous material. Dust from these tailings causes air pollution. 

3. Chemical like arsenic and iron are very harmful. When it rains these chemicals find their way to ground water, surrounding water bodies and soil. This pollutes water bodies as well as affects agriculture.
