Environment & Biodiversity MCQs

Notes:
Coastal Regulation Zone Notification, 2018 is based on the recommendations of Shailesh Nayak committee. Defense and strategic projects are exempted from regulations. For CRZ-III (Rural) areas, two separate categories have now been stipulated, i.e., CRZ-IIIA & CRZ-IIIB.

Notes:
Biocapacity refers to capacity of an area to provide resources and absorb wastes at the same time. When an area’s ecological footprint exceeds its biocapacity it results into unsustainability.

Notes:
Land Use, Land-Use Change, and Forestry, which is also termed as LULUCF is a green house inventory sector. It provides us a relatively cost-effective way of offsetting the green house emissions.

Notes:
The Least Developed Countries Fund (LDCF) was established in 2001 and is operated by the Global Environment Facility (GEF). It was established to support these countries work programme under the UN Framework Convention on Climate Change (UNFCCC).

Notes:
Biodegradable waste is a type of waste which can be broken down, in a reasonable amount of time, into its base compounds by micro-organisms and other living things, regardless of what those compounds may be. Wool is the textile fibre obtained from sheep and certain other animal products are organic in nature and thus can be degraded and be used as substrates for keratinase production.

Notes:
Checking atomic blasts will reduce radioactive pollution. Sewage pollution can be prevented by treating sewage before passing into water course, in sewage treatment plant or effluent treatment plant (ETP). Electrically operated vehicles will control automobile exhaust and improve the air quality in cities. Environmental pollution can be controlled by treating factory wastes before disposing of them. So, if we treat wastewater before disposing of in a river, it will surely decrease the amount of dumped pollutants. For example- Steel industries have a high concentration of cyanide in it, and it led to harmful effect. So, treatment is really necessary.

Notes:
Sultanpur National Park is located at Sultanpur, Haryana in Gurgaon District, Haryana. As a bird sanctuary it was the finding of Peter Jackson, famous ornothologist, and Honorary Secretary of the Delhi Birdwatching Society, who wrote to Prime Minister of India, Indira Gandhi, founder of the Society, in 1970 about the need to declare the Sultanpur jheel near Delhi, a bird sanctuary, and she asked him to take her there.

Notes:
Manas National Park is located in the Himalayan foothills of Assam. It is also a UNESCO Natural World Heritage site, a Project Tiger Reserve, and Elephant Reserve. It is contiguous with the Royal Manas National Park in Bhutan. Manas is famous for its population of the wild water buffalo.

Notes:
The Keibul Lamjao National Park is a national park in the Bishnupur district of the state of Manipur in India. It is 40 km2 (15.4 sq mi) in area, the only floating park in the world, located in North East India, and an integral part of Loktak Lake.

Notes:
The Great Barrier Reef, a UNESCO World Heritage Site, is the world’s largest coral reef system, spanning 2,300 kilometers and covering 344,400 square kilometers. It is home to 10% of the world’s fish species, 400 types of coral, and six of the seven species of marine turtles. The reef is composed of over 2,900 individual reefs and 900 islands, with the widest sections reaching up to 65 kilometers. It is visible from space and supports a diverse array of marine life, including whales, dolphins, and sharks. The reef has been listed as one of the Seven Natural Wonders of the World since 1997. Despite its natural beauty, the reef faces threats from climate change, coral bleaching, and pollution, with UNESCO recommending it for the In Danger list due to these impacts.
