Chapter 1 Flashcards
What is gross net income for different income classifications?
HIC (High-Income Country): $14,005 or more
MIC (Middle-Income Country): $1,145 - $4,515
LIC (Low-Income Country): $1,145 or less
14 is high for zero’s and 5’s. I likes1’s but not 45’s. 1 stuck in the middle of 5’s but wishes to be with 4 (i)
Income classifications are based on per capita gross national income as defined by the World Bank.
What is an ecological footprint?
Determines how dependent humans are on natural resources.
An ecological footprint measures the environmental impact of an individual, community, or organization.
What is sustainability?
The ability to meet the needs of the present without compromising the ability of future generations to meet their needs.
Sustainability encompasses environmental, social, and economic dimensions.
What are four unsustainable practices?
- Oil drilling – Depletes fossil fuels and harms ecosystems
- Overconsumption – Leads to resource depletion
- Food waste – Wastes energy, water, and land
- Cars – Emit greenhouse gases and contribute to pollution
These practices have long-term negative impacts on the environment.
What are five advantages of reservoirs and dams?
- Stores water for drinking and irrigation
- Provides flood control
- Generates hydroelectric power
- Creates new habitats
- Boosts tourism, helping the economy
Reservoirs can play a critical role in water management and energy production.
What are five disadvantages of reservoirs and dams?
- Displaces organisms
- Causes land loss
- High construction and maintenance costs
- Alters natural water flow
- Can lead to water quality issues
The environmental and social impacts of dams can be significant.
Why do governments build dams such as the Three Gorges Dam in China?
- Meet energy needs
- Control floods
- Boost the economy
- Provide a stable water supply
Large-scale dams are often seen as necessary for development and disaster management.
What are the advantages of groundwater removal?
- Useful for drinking and irrigation
- Available year-round
- No evaporation loss
Groundwater is a crucial resource in many regions, especially where surface water is scarce.
What are the disadvantages of groundwater removal?
- Aquifer depletion from overpumping
- Land subsidence (sinking of land)
- Pollution of aquifers lasting decades or centuries
Sustainable management of groundwater is essential to prevent long-term damage.
What are two solutions to reduce water waste?
- Grow efficient crops
- Raise water prices & repair leaking pipes
Efficient water use is critical in managing limited water resources.
What are two solutions to reduce food waste?
- Innovations that advance food preservation
- Meal planning
Reducing food waste can significantly impact resource conservation.
How does Singapore sustain its stability for energy supply?
3
Singapore uses natural gas, imports energy, and invests in renewable energy.
Diversification of energy sources is key to energy security.
How does Singapore sustain its stability for waste management?
3
Through recycling programs, incineration plants, and strict waste regulations.
Effective waste management strategies contribute to environmental sustainability.
How does Singapore sustain its stability for water supply?
Desalination, water recycling, and imports from Malaysia.
Water is woman and Malaysia is man. WM
Water scarcity solutions are critical in urban areas with limited natural resources.
How does Singapore sustain its stability for food supply?
3
Urban farming, food imports, and agricultural technology advancements.
Food security strategies are essential for densely populated cities.
How does Singapore sustain its stability for clean air management?
Air quality monitoring, strict vehicle emissions policies, and industrial regulations.
Clean air initiatives are vital for public health and environmental protection.
