Environment & Biodiversity MCQs

Notes:
The public must be informed and consulted on any proposed development under a project. Everyone who is affected by the proposed project is entitled to have access to the Executive Summary of the EIA.

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:
Littoral and Swamp Forests or the Mangrove Forests mostly contain sundari mangrove trees. The other main
species found in these forests are
casuarina trees, goran, gnewa, baen,
dhundal, etc.

Notes:
Acid rain is a rain or any other form of precipitation that is unusually acidic i.e. it possesses elevated levels of hydrogen ions (low pH). It is caused by emissions of oxides of sulphur (SO2 or SO3) and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.

Notes:
Basel Convention is an international treaty that was designed to reduce the movements of hazardous waste between nations, and specifically to prevent transfer of hazardous waste from developed to less developed countries (LDCs). It ultimately aims at biodiversity conservation.

Notes:
Ecology is the scientific study of interactions among organisms and their environment, such as the interactions organisms have with each other and with their abiotic environment. Topics of interest to ecologists include the diversity, distribution, amount (biomass), number (population) of organisms, as well as competition between them within and among ecosystems.

Notes:
The Taj Mahal, is slowly turning brownish-yellow because of air pollution, also called “Marble cancer”. The Industries located in and around Agra especially the Mathura oil refinery have been responsible for producing pollutants. Emissions of sulphur dioxide around the Taj Mahal are twice the permissible levels. Now, researchers found 3% of the deposits to be black carbon, around 30% organic carbon (or brown carbon) and most of the rest dust. Black carbon is emitted by vehicles and other machines that burn fossil fuels.

Notes:
Bandhavgarh National Park is located in the Umaria district of Madhya Pradesh. Bandhavgarh was declared a national park in 1968. This park is known for high density of Tigers. The park derives its name from the most prominent hillock of the area, which was said to be given by Hindu Lord Rama to his brother Lakshmana to keep a watch on Lanka (Ceylon).

Notes:
Mylo is a leather-like material made from mycelium, the underground root structure of mushrooms. Mylo is a sustainable alternative to leather because it can be grown without polluting substances. It is also more sustainable than synthetic leathers, which are usually made from petroleum-derived inputs.
Mylo is grown in a controlled indoor environment. The growing process is designed to be low impact and takes less than two weeks. It emits fewer greenhouse gases and uses less water and resources than animal-based leather.
Mylo is 80% bio-based and is completely biodegradable and compostable. However, when extra durability is needed, the mushroom leather is reinforced with polyurethane, which decreases its biodegradability.

Notes:
K’gari, also known as Fraser Island, is recognized globally as the largest sand island. Located in Queensland, Australia, this World Heritage-listed island covers a vast expanse of 120 kilometers. Further adding to its ecological significance, it harbors varied ecosystems ranging from rainforests to perched freshwater lakes. Notably, it serves as a habitat for a pure breed of dingoes and is home to Boomanjin Lake, the world’s largest perched lake. The island carries a historic and cultural resonance as it was once associated with the Butchulla people and used as an Allied training base during World War II.
