Environment & Biodiversity MCQs

Notes:
The phases involved in Environment Impact Assessment process in India are as follows: Screening, Scoping, Baseline data collection, Impact prediction, Assessment of alternatives, delineation of mitigation measures and environmental impact statement, Public hearing, Environment Management Plan, Decision making and Monitoring the clearance conditions.

Notes:
The impacts of the following is studied under Impact Prediction in Environment Impact Assessment:
1. Biological
2. Water
3. Land
4. Air
5. Noise

Notes:
The mitigation and compensation measures for all the identified significant impacts should be and financial plan for implementing the mitigation measures should be delineated under Environment Management Plan.

Notes:
Carbon Footprint is a measurement of all greenhouse gases that we produce individually and has units of tonnes (or kg) of carbon dioxide equivalent. It is made up of the sum of two parts, i.e., the primary footprint and the secondary footprint.

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:
Global hectare used as a measurement of biocapacity of the entire earth. One global hectare is a measurement of the average biocapacity of all hectare measurements of any biologically productive areas on the planet earth.

Notes:
Earth Hour is a global event which is organized by WWF. On this day households and businesses turn off their non-essential lights and other electrical appliances for an hour to raise awareness towards the need to take action on climate change.

Notes:
Lingambudhi Lake is a lake in the city of Mysore, Karnataka.

Notes:
An air pollutant is a substance in the air that can have adverse effects on humans and the ecosystem. Because of its role as a greenhouse gas Carbon dioxide (CO2) has been described as “the leading pollutant” and “the worst climate pollution”. Other examples include carbon monoxide gas from motor vehicle exhaust, or the Sulphur dioxide released from factories.

Notes:
Lichens are found in both nature and in human-made environments, including rocks, trees, barren earth, metal and concrete. They are sensitive to air pollution because they receive all nutrients from the atmosphere, which makes them valuable as indicator species. The presence of sulphur dioxide force them to perish.
