Key Points
Define 'Environment'.
Environment encompasses all biotic and abiotic factors; includes resources like air, water, and life forms.
List four functions of the environment.
1) Supplies resources, 2) Assimilates waste, 3) Sustains life through biodiversity, 4) Provides aesthetic value.
What are renewable and non-renewable resources?
Renewable resources regenerate (e.g., forests); non-renewable resources diminish (e.g., fossil fuels).
Explain environmental degradation.
Environmental degradation results when resource extraction exceeds regeneration, threatening ecological balance.
What is carrying capacity?
Carrying capacity refers to the maximum load an environment can sustain without degradation.
Global warming causes.
Primarily caused by greenhouse gas emissions from fossil fuel combustion and deforestation.
Effects of ozone depletion.
Increased UV radiation leads to skin cancer and disrupts ecosystems, affecting aquatic and terrestrial life.
Air pollution in urban India.
Mainly due to vehicle emissions; significant increases in respiratory diseases among urban populations.
Identify sustainable development.
Development that satisfies current needs without compromising future generations' ability to meet theirs.
UN Sustainable Development Goals.
17 goals aim to address global challenges like poverty, inequality, climate change, and sustainability by 2030.
What is biocomposting?
Recycling organic waste into compost, reducing chemical fertilizer usage, and enhancing soil health.
Definition of biodiversity.
Biodiversity refers to the variety of life forms on Earth, crucial for ecosystem resilience and stability.
Environmental cost of industrialization.
Industrial growth leads to pollution and resource depletion, which in turn affects public health and ecology.
Explain 'Sustainable energy sources'.
Renewable sources like wind, solar, and tidal energy have minimal environmental impacts compared to fossil fuels.
Role of Pollution Control Boards.
Established to monitor and control air and water pollution, setting standards for emissions and effluents.
Impact of population explosion.
Rapid population growth causes increased demand for resources, leading to over-extraction and environmental stress.
Significance of the Chipko Movement.
Grassroots initiative aiming to protect trees by hugging them, raising awareness about deforestation.
What is 'Opportunity cost' in environmental terms?
Represents the economic losses due to environmental degradation, affecting future resource availability.
What is ecological sustainability?
Maintaining the health of ecosystems while supporting human life, requiring responsible resource management.
Draw the relationship between economy and environment.
A sustainable economy relies heavily on environmental health, highlighting the interdependence of both systems.
