It’s worse for sedentary species like reptiles, small mammals, beavers and burrowing rodents, all of whose primary habitat is the Earth’s surface. Pollution of aquatic habitats is another outcome of surface mining for coal. Wastes and chemicals from it trickle and seep into streams, rivers and underground water-bodies.
How does coal affect wildlife?
In addition to potentially severe heart and respiratory problems, coal dust can impair the ability of leaves to photosynthesize and oxidizing coal particles can settle in waterways, reducing the oxygen available for aquatic wildlife.
What animals were used in coal mines?
Canaries were iconically used in coal mines to detect the presence of carbon monoxide. The bird’s rapid breathing rate, small size, and high metabolism, compared to the miners, led birds in dangerous mines to succumb before the miners, thereby giving them time to take action.
What’s bad about coal mining?
Air pollution from coal-fired power plants is linked with asthma, cancer, heart and lung ailments, neurological problems, acid rain, global warming, and other severe environmental and public health impacts.
How does coal mining affect the environment?
Coal mining harms land, surface waters, groundwater and even our air. 4 Impacts to the land from mining cause drastic changes in the local area. Damage to plants, animals and humans occurs from the destruction and removal of habitat and environ- mental contamination.

What are the disadvantages of coal?
The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.
Is Coal good for environment?
Coal provides many jobs. Unlike other forms of energy (nuclear, natural gas, oil, hydroelectric), coal provides many jobs in removing coal from the earth, transporting it to the utility, burning it, and properly disposing of coal ash. … Coal can be mined and burned with little environmental impact.
