- Soil contamination or soil pollution as part of land degradation is caused by the presence of xenobiotics (human-made) chemicals or other alterations in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals, or improper disposal of waste.
- Fungi and bacteria found in the soils cannot bind the soil due to chemical changes and this causes soil erosion. Large tracts of land become barren; unable to support any life on it. Even the plants that do grow on these lands will absorb the toxins and transfer them to the food chain.
Key-Points
Hydropower
- Hydropower is electrical energy produced through the power of moving water. In modern technology, hydropower moves turbines that pass on their energy to a generator which then produces electric power. Hydropower is a type of renewable energy, and once the power plant is constructed it produces little to no waste.
- Hydropower plants convert potential energy into mechanical energy through water turbines, which then generate electricity.
- The main purpose is to store energy by pumping water up into the upper reservoir during low-demand periods and generate (peaking) power by releasing the water back to the turbine during high-demand periods.
Additional Information
Transport sector
- The environmental impact of transport is significant because transport is a major user of energy, and burns most of the world's petroleum. This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through the emission of carbon dioxide.
- Transportation, as a component of the tourism industry, has many side effects on the environment due to carbon dioxide emissions, pollution, etc. The work mainly emphasizes the way in which air, road, rail, and water transportation influence the quality of the environment, contributing to global warming at the same time.
Agriculture sector
- Agriculture and livestock activities pollute soil through the excessive application of pesticides and fertilizers, the use of untreated wastewater for irrigation, and the use of manure and sewage sludge with high antibiotic, antimicrobial-resistant bacteria, and heavy metal content.
Thermal power plants
- Since the thermal power plants and the ash ponds are located in densely populated areas, there is a potential chance for contamination of soil and groundwater of the surrounding areas from the toxic trace elements in the ash. These elements are also enriched in the pond ash.
Since Hydropower plants are not a source of pollution in soil
Therefore Option 4 is the correct answer.
