Insights Static Quiz -345, 2019–Environment

Solution: a)

Epiphytic (plants growing on other plants including those growing on rock boulders and often termed lithophyte),

Terrestrial (plants growing on land and climbers)

Mycoheterotrophic (plants which derive nutrients from mycorrhizal fungi that are attached to the roots of a vascular plant).

Solution: b)

Global Environment Outlook report has been released. The report is the sixth and is the UN’s most comprehensive report on the state of the global environment since the fifth edition in 2012.

• The GEO is often referred to as UN Environment’s flagship environmental assessment.
• The first publication was in 1997 and was originally requested by Member States.

GEO global assessments provide an integrated analysis (e.g. social, economic, environmental) of major trends that have shaped the environment. These reports provide world leaders with policy options to take immediate action to address environmental issues by turning environmental discussions into practice.

The Orang National Park is located on the north bank of the Brahmaputra River in the Darrang and Sonitpur districts of Assam.

The park has a rich flora and fauna, including great Indian one-horned rhinoceros, pygmy hog, elephants, wild buffalo and tigers. It is the only stronghold of rhinoceros on the north bank of the Brahmaputra river.

The Orang National Park is popularly known as the “mini Kaziranga.” The reason behind this is that both the parks have the same kind of climate and ecology.

The United Nations Environment Assembly was created in June 2012, when world leaders called for UN Environment to be strengthened and upgraded during the United Nations Conference on Sustainable Development, also referred to as RIO+20.

The United Nations Environment Assembly is the world’s highest-level decision-making body on the environment. It addresses the critical environmental challenges facing the world today. Understanding these challenges and preserving and rehabilitating our environment is at the heart of the 2030 Agenda for Sustainable Development.

The Environment Assembly meets biennially to set priorities for global environmental policies and develop international environmental law. Through its resolutions and calls to action, the Assembly provides leadership and catalyses intergovernmental action on the environment.

Solution: d)

Bioleaching is a simple and effective technology for metal extraction from low-grade ores and mineral concentrates. At present bioleaching is used essentially for the recovery of copper, uranium and gold.

Biosparging is an in-situ remediation technology that uses indigenous microorganisms to bio-degrade organic constituents in the saturated zone. In biosparging, air (or oxygen) and nutrients (if needed) are injected into the saturated zone to increase the biological activity of the indigenous microorganisms. Biosparging can be used to reduce concentrations of petroleum constituents that are dissolved in groundwater, adsorbed to soil below the water table, and within the capillary fringe.

Bioremediation strategies can involve natural attenuation, bioaugmentation, or biostimulation and can take place in situ or ex situ.
