The rapidly growing population, urbanization and changing consumption patterns in India has led to the generation of vast quantities of solid waste. As per the Swachhata Sandesh Newsletter released by the Ministry of Housing and Urban Affairs in January 2020, 1,47,613 metric tonnes of solid waste is generated per day, from 84,475 wards across India. The existing process for collection, transportation and disposal, as part of municipal solid waste management, is under undue stress. Thus, improper solid waste disposal poses a great risk to public health.
Rice is among the top three crops produced in Malaysia, and it is the staple food for the majority of the population. According to estimates, the adult population consumes 2.5 plates of white rice on average every day. In a year, the average consumption of a Malaysian resident is approximately 82.3 kg of rice.
Today, fertilizers are considered as an integral part of modern agriculture. One of the reasons why fertilizers are extensively used is because they provide important nutrients for better plant growth and crop productivity. However, the overuse of fertilizers has deeply affected the environment in myriad ways. It also threatens to impact human health.
Bangladesh, has a chiefly an agrarian economy where rice is the dominant crop. The climatic condition in Bangladesh also enables the year-round production of rice. Thus, rice is an integral part of the dietary culture and the main source of nutrition for the people. Also, rice production is the major source of income in rural areas.
Cleaning is a top priority in hotels, restaurants, and cafes. Although washing an infinite amount of dishes, pots, pans, and utensils may be a challenging chore, maintaining good hygiene standards is critical. It is also important for consumer loyalty. But in pursuit of better cleaning, you should not opt for dish wash liquids that may contain potentially harmful chemicals or ingredients.
Though we may have heard that manual scavenging is a thing of the past, the reality check is a shocker. In a small time span of just about a month, as many as 10 sanitation workers died. The only relief, though too late for the poor souls lost is that the government has responded with prompt action and focused on the implementation part of the law it had framed long ago.
The word plastic comes from the Greek word “plastikos”, which means ‘able to be molded into different shapes’. Plastics are made up of linking of monomers together by chemical bonds. Polythene comprises of 64% of total plastic, which is a linear hydrocarbon polymers consisting of long chains of the ethylene monomers. General formula of polyethylene is CnH2n, where ‘n’ is the number of carbon atoms. The plastics we use today are made from inorganic and organic raw materials, such as carbon, silicon, hydrogen, nitrogen, oxygen and chloride. The basic materials used for making plastics are extracted from oil, coal and natural gas. Plastics include polythene, propylene, polystyrene, polyurethane, nylon etc. Polyethylene either LDPE (low density polyethylene) or HDPE (high density polyethylene) is a thermoplastic polymer made by monomers of ethylene, used mostly as thin films and packaging sheets.
The Deepwater Horizon oil spill, which began on April 20, 2010, is the largest marine oil spill in the history of the petroleum industry. It is purported to be 8-31% larger than the previous largest spill, Ixtoc 1 oil spill. The US government estimated the overall discharge at 4.9 million barrels or 210 million US gallons.
The world we see today has come into existence through a journey of evolution for millions of years, leaving biodiversity as its trail. Biodiversity represents the variety of life on earth and the various forms of their associations. We are completely dependant upon this network of life, which we are an integral part of.
Rapid scale urbanization in a population of 1.34 billion Indians, growing exponentially at a growth rate of 1.2% has surmounted the issue of untreated sewage rapidly degrading the life cycle of flora and fauna. Untreated sewage surmounts to approximately 75% of the surface water contamination in the country. When sewage enters a lake or stream, microorganisms begin to decompose the organic materials. This impacts both the ecology and economy as well as imposes severe health risks. Sewage-contaminated water causes eutrophication, which is the increase in concentration of chemical elements required for life, thus decreasing the amount of dissolved oxygen necessary for aquatic life. Sewage pollution has been attributed to causing gastrointestinal disorders in humans like Giardiasis, Amoebic Dysentery and Cholera. Moreover debris associated with sewage hampers the aesthetic value of the environment.
