Environment & Biodiversity MCQs

Notes:
The Umbrella Group is a coalition of 12 non-european developed countries that was formed following the adoption of the Kyoto Protocol. The Group is made up of Australia, Belarus, Canada, Iceland, Israel, Japan, New Zealand, Kazakhstan, Norway, the Russian Federation, Ukraine, and the United States.

Notes:
A Red Data Book contains lists of species whose continued existence is threatened. Species are classified into different categories of perceived risk. It documents rare and endangered species of animals, plants and fungi, as well as other living organisms in an area, region or country.

Notes:
An Air Quality Index (AQI) of 301-500 is considered as hazardous to human health. It denotes the severely polluted state of air. AQI values over 300 trigger health warnings of emergency conditions. The entire population is even more likely to be affected by serious health effects.

Notes:
The Basel Protocol on Liability and Compensation was adopted at the Fifth Conference of Parties (COP 5) on10 December 1999. The objective of the Protocol is to provide for a comprehensive regime for liability as well as adequate and prompt compensation for damage resulting from the transboundary movement of hazardous wastes and other wastes, including incidents occurring because of illegal traffic in those wastes.

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:
The predominant wild animal species that inhabits the Park is the deer, of which the most easily sighted are the graceful little chinkara or Indian gazelle, and the chital. Other species that have their habitat in the park are nilgai, sambar, chausingha or four-horned antelope, blackbuck, sloth bear, leopard and the common langur.

Notes:
Gahirmatha Marine Sanctuary is a marine wildlife sanctuary located in Odisha that is the world’s largest nesting beach for Olive Ridley Turtles. It extends from Dhamra River mouth in the north to Brahmani river mouth in the south. It is the one of world’s most important nesting beach for turtles.

Notes:
Ecological sanitation is a sustainable system for handling human excreta, using dry composting toilets. This is a practical, hygienic, efficient and cost-effective solution to human waste disposal. With this composting method, human excreta can be recycled into a resource (as natural fertiliser), which reduces the need for chemical fertilisers.

Notes:
Glover’s Reef is a part of The Belize Barrier Reef Reserve System, a UNESCO World Heritage Site since 1996. This is the world’s second largest reef system, extending 300 km along the coast of Belize. It’s a host to seven protected areas inclusive of three atolls: Turneffe, Lighthouse, and Glover’s Reef. The complex supports 1,400 known species, among them 17 endangered ones such as the American crocodile, manatee, and different sea turtles. The system, notable for its pristine condition, was deemed by Charles Darwin as the “most remarkable reef in the West Indies”.

Notes:
The Iguaçu National Park is a World Heritage Site straddling the borders of Brazil and Argentina. This locale is famous for the panoramic Iguaçu Falls, consisting of about 275 individual falls, spanning 2,700 meters. Most importantly, the park serves as a sanctuary for numerous rare animals like jaguars, ocelots, and jaguarundis. The phenomenal waterfall isn’t only a top tourist attraction but also an important habitat for species like the great dusky swifts. Proclaimed a World Heritage Site by UNESCO in 1984, the park exemplifies global importance in wildlife conservation.
