Earth and every living organism on this planet require water for survival and without water there would be no life. Drinking water should be clean that means it should be free from micro-organisms, free from harmful chemical and other pollutants. Consuming unsafe drinking water may lead to several water borne diseases, and other long term and chronic health problems. Water conservation encompasses the policies, strategies and activities to manage fresh water as a sustainable resource to protect the water environment and (...) to meet current and future human demand. Water conservation in simple words, is an effort to save water and ultimately save the planet. Water conservation is needed to protect the ecosystem and to restore its fast deterioration and to overcome the threats of environmental degradation, to meet the unavoidable emergency of shortage for drinking and domestic water in near future.

Everywhere in the world, and in every period of human history, it has been common for energy decisions to be made in an ethically haphazard manner. With growing population pressure and increasing demand for energy, this approach is no longer viable. We believe that decision makers must include ethical considerations in energy decisions more routinely and systematically. To this end, we propose an applied ethics framework that accommodates principles from three classical ethical theories—virtue ethics, deontology, consequentialism, and two Native American (...) ethics (Lakota and Navajo)—all considered from the perspectives of the impacted communities. We illustrate this framework by evaluating five recent energy decisions: the Dakota Access Pipeline, the Navajo Nation’s possible transition from coal to solar, hydraulic fracturing in Pennsylvania, uranium mining in Virginia, and the construction of the Xiaolangdi Dam in China. An applied ethics framework is preferable to existing ethical analyses because it can serve to sharpen arguments for (un)ethical decisions and action. Rather than treat ethical reasoning as a matter of opinion, we argue that applying ethical principles in a universal and standardized way adds rigor to energy sector decisions by presenting a position available for objective scrutiny. Because our framework identifies which aspects of a targeted action (if any) must adjust to improve ethical merit, it can serve as a practical tool for improving decision-making as we enter a new era of energy transitions.

During the microscopic anatomical study of a fresh water siluridfish, Wallago attu,a new trematode species Opisthorchis varunai was recorded from the gallbladder. The fish was collected from the Varuna River in Varanasi. The newly reported species has been described in detail, discussed and compared with other species of the genus Opisthorchis. It has elongated spinose body, bluntly pointed at anterior and posterior extremities, entire ovary, ventral sucker pre-equatorial, unlobed testes and presence of pre-pharynx. It has been distinguished by other species (...) through the absence of a crown of spines around the excretory pore. (shrink)
