Environment & Biodiversity MCQs

Notes:
Decreasing poverty, prevention and control of pollution, conservation biological diversity are some of the important aspects of Sustainable Development. It is can alternative approach to the theories of development, presently.

Notes:
Both Statements are correct:

1. Algal bloom refers to a rapid increase or accumulation in the population of algae in an aquatic ecosystem.
2. Algal blooms can occur in freshwater as well as marine environments.

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:
Special Climate Change Fund was established in 2001. Adaptation to climate change is the top priority of the Special Climate Change Fund. The financial mechanism is operated by the Global Environment Facility (GEF).

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:
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:
Fuel cells do not emit any pollution at their point of use when run on pure hydrogen. The “well-to-wheels” emissions of fuel cell electric vehicles running on renewable hydrogen (extracted from water using clean energy) are almost 100 percent lower than those of conventional gasoline vehicles.

Notes:
An ecosystem is a community of living organisms in conjunction with other living and nonliving components of their environment, interacting as a system. The nature of the organisms—the species, functional groups and trophic levels to which they belong—dictates the sorts of actions these individuals are capable of carrying out, and the relative efficiency with which they do so.

Notes:
Forests are home to a large number of plants and animals. They are the “green lungs” and serve as water purifying systems of nature. In a forest, there are various types of interactions that occur between the living and the non-living components. The oxygen released during photosynthesis is used by the animals for respiration. In this way, plants and animals help in maintaining the balance of oxygen and carbon dioxide in the atmosphere. Therefore, forests can be considered as a dynamic living entity.

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.
