• Gypsum is used as a fertiliser; it is a moderately soluble source of the essential plant nutrients, calcium and sulphur, and can improve overall plant growth. Gypsum amendments can also improve the physical and chemical properties of soils, thus reducing erosion losses of soils and nutrient concentrations (especially phosphorus) in surface water runoffs.
• Gypsum is the most commonly used amendment for sodic soil reclamation and can be included as a component in synthetic soils used in nursery, greenhouse, and landscape applications. These multiple uses of gypsum represent potential benefits to agricultural and horticultural users.
• PoP is made by heating gypsum at temperatures in the range of 300$^\circ$F. When it comes in contact with water, the material regains the form of gypsum. Since gypsum is a naturally occurring substance, and is used as a soil-conditioner to reclaim saline-sodic soils, it has been argued by idol-makers' associations that it is harmless to the environment.
• This argument, however, is trashed by activists who argue that PoP idols are non-biodegradable. A test carried out at the Centre for Environmental Science and Engineering at IIT-Mumbai, showed that these idols remain intact for several months in still water, as compared to clay idols which dissolve within 45 minutes.

In 2017, pollution was responsible for 15% of all deaths globally, and 275 million Disability-Adjusted Life Years. India saw the most pollution deaths - about 2.3 million - a new report has found. The 2019 Pollution and Health Metrics: Global, Regional and Country Analysis report from the Global Alliance on Health and Pollution (GAHP) updates findings from The Lancet Commission on Pollution and Health, and provides a ranking of pollution deaths on global, regional and country levels. The report uses the most recent Global Burden of Disease data from the Institute of Health Metrics Evaluation. The top 10 countries with the most pollution deaths include both the world's largest and wealthiest nations, and some of its poorer ones. India is followed by China in the number of pollution deaths, with about 1.8 million. The United States makes the top 10 list with 1,97,000 pollution-related deaths, while ranking 132nd in the number of deaths per 100,000 people.

The Himalayan Ibex (Capra sibirica hemalayanus) is regarded as a subspecies of the Siberian Ibex (Capra sibirica). They are found in mountain ranges of central and northeastern Afghanistan, China, north India (Himalayas of Jammu and Kashmir and Himachal Pradesh), eastern Kazakhstan, Kyrgyzstan, Mongolia, northeastern Uzbekistan, northern Pakistan, Russia, and Tajikistan. An adult ibex weighs about 90 kgs, and stands around 40 inches tall, with huge curved horns. The horns have notches on the front, and grow each year. Their coat is thick and woolly in winter, and shed in early summer. Colour ranges from pale brown to dark brown, with a darker dorsal stripe. They are usually found in small herds and sometimes around 50 together. They normally feed on grass, moss and small shrubs. In winter, they come down to lower elevations in search of food as the mountains get covered in snow. In summer they move back upward as the snow melts. According to IUCN Red list it is least Concern species.
