Human-induced activities such as building reservoirs for holding floods and storing water are said to lessened erosion, but geologists do however argue that building artificial reservoirs encourage erosion since the bulk of erosions takes place above dams. Destruction of the forest is also among activities that encourage floods and promote erosion by interfering with the natural circulation of air and water. Man’s activities interfere with natural agents by causing abrasion and removing weathered and un-weathered rocks. These activities encourage the formation of quarries as a result of glacially formed corries cutting through channels causing artificial cuttings. Man as a geological agent has modified geographical conditions by destructing sea coasts, and reclamation of land has caused adverse action on inanimate nature.
Other events or processes caused by human activities include; underground mines, disposal of industrial waste, and strip mining. Underground mining such as extracting base metals, limestones, gypsum have created potential hazards to the natural environment by causing roofs to collapse, surfaces to collapsing, increasing acids and toxic waters, and mine flooding. Strip mines and Open-Pit Mines, on the other hand, have caused open strip mines and open-pit mines brought about by large-scale quarrying and open pit mining for stones, asphalt, other nonfuel resources, stone, gravel, and sand. Coalfields were developed as a result of large earth-moving equipment resulting from surfacing mining-ponds and acidic or even toxic water resources. Also, highway and quarry benches may collapse, and fill materials may not be fully compatible with the natural soil leading to land subsiding.
Industrial-waste disposal in geologic formations, both liquid and solid industrial waste disposals that include surface burials in soils or rock units, and subsurface injections for liquid as a result of industrial waste may be toxic to natural waterways. In this regard, selecting a suitable place for disposing of waste will ensure waste remains isolated from the groundwater aquifers and biosphere. Conclusively, disposing of waste materials in permeable sedimentary rocks such as dolomite and sandstone surrounded by strata to assure waste containment should be practiced.
