Polar bears (Ursus maritimus)-classified as a marine mammal, roam the arctic sheets and swim in the region’s coastal waters. As these bears depend on sea ice for their existence and are directly impacted by global warming and climate change, it makes them a significant indicator species (Ramsay M., 1998). Polar bears are also on the top of the very long Arctic marine food chain and by measuring the levels of contaminants in their tissues; scientists get an idea of the degree of contamination of the Arctic marine ecosystem.
Now, a new worrisome study has surfaced which says that Polar bears in and around Svalbard in the Arctic are found to be carrying increased loads of mercury in their bodies. The study, published in the journal Environmental Science and Technology on May 15, 2020, says that the increasing load of mercury–a potent neurotoxic pollutant, in the bodies o...

Each of the nine chapters of this book showcases an outlook on pertinent social issues. From the ever-changing evils of society and how together we can solve day-to-day problems to what the responsibility of society towards orphans should be and how to prevent their criminalization have been discussed threadbare. Khanna has selected topics unrelated to politics and governments, addressing the smallest unit of a nation - the family. He attributes problems to the departure from India's roots and highlights instilling the nation's ageold cultural ethos among children. Khanna hails from Punjab where, in the recent decades drug addiction among the young population has emerged as a significant problem.
