SCIENCE AND SOCIETY

                    As the planet moves away from fossil fuels towards a green future, the focus now is on the ramping up of mining for various rare earth minerals like Lithium, Cobalt and Nickel. These minerals are crucial for the production of batteries, solar panels, and wind turbines which are going to replace our fossil fuel-based society in the future by 2040. To achieve this objective, we will see a 4 to 6 times increase in the overall requirement of these minerals by 2040:  for Lithium, it is 40 times higher, and for Cobalt and Nickel 20 to 25 times higher. However, the ramping up of these minerals has been slow enough to meet the energy transition goals of the Paris Agreement as it is plagued by a lot of hurdles like technical barriers, environmental and ethical issues.         First, their mining is a time taking process and it often takes nearly 5 to 10 years for these minerals from mines to reach the market. Secondly, as the source of these minerals is very scarce and l

     Bringing back horrifying memories of Hitler’s gas chamber death camp, Delhi awoke on Monday (November 15, 2021) to find itself shrouded in a toxic grey haze smog, with the air quality plummeting several steps below the safety level. The Air Quality Index (AQI) reached the 490 mark on this day coming under the ‘Severe’ category condition. A blanket of thick smog enveloped the skies of the national capital in the worst ever incidence of air pollution. The pollution level became so dire and menacing that it prompted a stern warning issued from the Supreme Court directing the state and federal governments to take "imminent and emergency" measures to tackle the situation. Following this, t he Delhi government has to shut down schools until further notice, urge people to work from home, and ban non-essential trucks from entering the capital due to dangerous levels of air pollution.           Air Quality Index of a locality is generally measured by the presence of Suspended P
