Thermal Pollution as the Unseen Side of Water Pollution

When we talk about pollution, thermal pollution rarely comes to our minds. However, with the innumerable thermal power plants and industries mushrooming everywhere, thermal pollution is a real and persistent problem of current times. Thermal pollution in the broadest sense can be defined as the abrupt change in ambient temperature of a natural water body by any human induced processes. The increase or decrease of water temperature degrades the quality of water and makes it unfit for consumption...

Nuclear Power in India and the Fight Against Climate Change

Nuclear power carries with it the ignominy of leading to risks that can be very devastating for health and environment, which can result in vociferous public opposition to the endorsement of nuclear technology, especially in developed economies. In fact public opposition led to the collapse of the Italian government’s plans for a nuclear industry. Germany plans to phase out all of its reactors by 2022, and Belgium is soon to follow. Also, after the Fukushima disaster, Japan had shut down the reactor,...

Antarctic Iceberg Measuring 5800 sq km Breaks from Larsen C Shelf

National Aeronautics and Space Administration (NASA) of the US estimates that an Antarctic iceberg measuring 5,800 sq km in area broke off from the mainland Antarctic continent between July 10 and 12, 2017 (NASA, 2017). The Antarctic iceberg has broken off from the Larsen C ice shelf, which is the fourth-largest ice shelf around Antarctica. The Larsen C ice shelf is located at the eastern side of the tip of the Western Antarctic Peninsula. An ice shelf is a floating sheet of ice that is permanently...

Drought Disaster Areas and the Need for Smart Management

Drought is a climatic condition, which is characterized by lack of precipitation and dryness. Drought prone areas are identified by a deficit of rainfall received in a  particular area. The parameters to identify drought prone areas vary depending on the natural climatic conditions. To tackle the impacts of drought disasters several governmental policies have been framed at national and state level. Effective implementation of the existing institutional framework and advancement in sustainable technology...

Mercury Pollution a Severe Risk without Proper Regulation

Defining mercury pollution The human body utilizes certain metals in moderate quantities such as iron, for beneficial purposes. However, other metals such as mercury and lead may have toxic effects on the biological processes of humans as well as the ecosystem. Mercury in fact is understood to be the most toxic heavy metal that occurs in a liquid state at normal temperatures. Mercury always appears in compounds and does not occur freely in nature. In its pure form, the heavy, odourless, and lustrous...

Statistically understanding desertification in India, a disturbing truth

The terms desertification refers to degradation of land in arid, semi-arid and sub-humid areas resulting from various factors, including climatic variations and human activities. It does not imply loss of land to desert or through sand-dune movement. Land degradation occurs everywhere, but is known as desertification when it occurs in the dryland ecosystems, i.e. land areas where the mean annual precipitation is less than two thirds of potential evapotranspiration (PET = potential evaporation from...
