8 Most VSAQ’s of Environmental Economics Chapter in Inter 2nd Year Commerce (TS/AP)
2 Marks
VSAQ-1 : Ecosystem.
Ecosystems are distinct geographical areas comprising both living (biotic) and non-living (abiotic) components. These systems are influenced by various environmental factors, such as climate, sunlight, temperature, and rainfall, which regulate the interactions within them. Ecosystems play a crucial role in maintaining ecological balance and sustaining life on Earth.
VSAQ-2 : Water pollution.
Water pollution refers to the introduction of harmful substances or contaminants into bodies of water, including rivers, lakes, oceans, and groundwater. This pollution alters their chemical, physical, or biological properties, posing detrimental effects on the environment and harming living organisms.
VSAQ-3 : Sustainable development. (OR) What is Sustainable Development? (OR) Explain the Sustainable Development?
Sustainable development is an approach to economic and social development that prioritizes meeting the needs of the present generation while ensuring the ability of future generations to meet their own needs. It involves balancing economic growth with a strong emphasis on environmental protection and social equity. The core principle is to use resources in a manner that does not deplete them for future use and to ensure that the benefits of development are equitably shared among all members of society. Sustainable development is a comprehensive concept that seeks to promote the long-term well-being of both people and the planet.
VSAQ-4 : What are the types of environment?
The three types of environments are:
- Physical Environment: This includes non-living elements such as air, water, soil, climate, and geological features. It forms the foundation for all life on Earth and plays a critical role in shaping ecosystems.
- Biotic Environment: This encompasses all living organisms, including animals, plants, microorganisms, and humans. The interactions and relationships between these living entities are essential for the functioning of ecosystems.
- Social or Cultural Environment: This pertains to the human-made environment, including cultural practices, social structures, traditions, and lifestyles. It reflects how human societies interact with and adapt to their physical and biotic surroundings.
VSAQ-5 : Environmental Degradation.
Environmental degradation refers to the deterioration of the natural environment caused by pollution, landfills, land disturbance, deforestation, industrialization, and overproduction. It harms ecosystems, depletes resources, and threatens biodiversity. Solutions involve sustainable practices and pollution control to protect the environment.
VSAQ-6 : Green house effect.
The greenhouse effect is the process where certain gases in the atmosphere, such as carbon dioxide and methane, trap heat from the sun and prevent it from escaping into space. This leads to a warming of the Earth’s surface and is responsible for climate change.
VSAQ-7 : Renewable and non-renewable resources.
Renewable resources can be naturally replenished, like water and forests. Non-renewable resources, on the other hand, cannot be naturally replaced and will eventually run out, such as fossil fuels like coal, oil, and natural gas.
VSAQ-8 : Air pollution.
Air pollution is the contamination of the air with harmful pollutants, which can have adverse effects on both living organisms and the environment. It can be caused by various sources, including agricultural activities, industrial manufacturing processes, the use of solvents and combustion, and even nuclear energy programs.
