Explain the land pollution?

The land pollution is where our land may be as far as being contaminated. All of the bad toxic chemicals and waste, that is left or dumped on our land, causes it to become polluted. Industrial activities also contribute to land pollution. For example, in open cast mining, enormous holes are dug in the ground and these form dangerously deep mining pools. Roads cause visual, noise, light, air and water pollution, in addition to land pollution.
