Flashcards
0/30
Rare Metals Scarcity
Consequences: Technological growth impediment, increased electronic waste, and innovation for substitutes. Examples: Indium used in touchscreens, Tantalum in electronics.
Nuclear Energy Waste
Consequences: Long-term storage challenges, potential for environmental contamination, and public health concerns. Examples: Fukushima Daiichi disaster, Yucca Mountain (USA).
Groundwater Depletion
Consequences: Lowered water tables, land subsidence, and reduced surface water supplies. Examples: Ogallala Aquifer (USA), North China Plain.
Fisheries Depletion
Consequences: Collapse of fish stocks, loss of livelihoods for fishermen, and disruption of marine ecosystems. Examples: Atlantic Cod Fishery, Bluefin Tuna.
Coal Burning
Consequences: Air pollution, acid rain, and health risks due to heavy metals. Examples: Smog in Beijing (China), Acid mine drainage in Appalachia (USA).
Fossil Fuel Consumption
Consequences: Air pollution, global warming, and geopolitical tensions. Examples: Smog incidents, melting of polar ice caps.
Natural Gas Flaring
Consequences: Wastage of resources, contribution to climate change, and health issues due to air pollution. Examples: Flaring in Nigeria's Niger Delta, Bakken Formation (USA).
Atmospheric Carbon Dioxide Increase
Consequences: Global warming, ocean acidification, and alteration of plant growth. Examples: Keeling Curve, climate change impact on coral reefs.
Peatland Degradation
Consequences: Carbon release, loss of biodiversity and disruption of water regulation. Examples: Destruction of Indonesian peatlands, draining of peat in Scotland.
Mangrove Clearing
Consequences: Loss of coastal protection, fisheries decline, and carbon storage reduction. Examples: Southeast Asia shrimp farms, Nigerian mangrove forests.
Hydraulic Fracturing Impact
Consequences: Ground and surface water contamination, induced seismicity, and air quality degradation. Examples: Fracking in Marcellus Shale (USA), Earthquakes in Oklahoma.
Plastic Pollution
Consequences: Marine life endangerment, microplastics in the food chain, and beach aesthetic degradation. Examples: Great Pacific Garbage Patch, microbeads in cosmetics.
Pesticide Overuse
Consequences: Soil and water contamination, non-target species affected, and pest resistance development. Examples: Colony Collapse Disorder in bees, DDT impacts in the mid-20th century.
Non-native Species Invasions
Consequences: Disruption of local ecosystems, economic implications for agriculture and fisheries, and extinction of native species. Examples: Zebra mussels in the Great Lakes, Cane Toads in Australia.
Urban Sprawl
Consequences: Habitat fragmentation, increased vehicle emissions, and loss of agricultural land. Examples: Expansion of Los Angeles, São Paulo's growth.
Deforestation
Consequences: Loss of biodiversity, disruption of water cycles, and increased greenhouse gases. Examples: Amazon rainforest, Borneo forests.
Voluntary vs. Forced Migration
Consequences: Social tensions, strain on urban infrastructure, and loss of cultural landscape. Examples: Syrian refugee crisis, rural-to-urban migration in China.
Soil Degradation
Consequences: Lowered agricultural productivity, increased erosion, and desertification. Examples: Dust Bowl event (USA), Aral Sea region (Central Asia).
Topsoil Erosion
Consequences: Decreased agricultural productivity, sedimentation in waterways, and loss of soil fertility. Examples: Erosion of the Loess Plateau (China), Midwest USA topsoil loss.
Freshwater Ecosystem Alteration
Consequences: Disruption of aquatic life, increased vulnerability to invasive species, and altered sediment transport. Examples: Dams on the Mississippi River, diversion of Aral Sea.
Industrial Water Pollution
Consequences: Habitat degradation, human health risks, and disruption of food chains. Examples: Cuyahoga River fires (USA), Bhopal disaster (India).
Oil Depletion
Consequences: Economic vulnerability, energy shortages and increased exploration risks. Examples: Peak Oil Theory, North Sea oil fields.
Mineral Resource Exhaustion
Consequences: Scarcity of raw materials, increased mining costs and innovation in recycling/replacement. Examples: Rare earth elements, De Beers diamond mines.
Desertification
Consequences: Reduction in land productivity, exacerbation of poverty, and increased conflict over resources. Examples: Sahel region (Africa), Gobi Desert expansion (China).
Phosphorus Cycle Disruption
Consequences: Eutrophication, biodiversity loss in aquatic systems, and food production impact. Examples: Algal blooms, dead zones in the Gulf of Mexico.
Ozone Layer Depletion
Consequences: Increased levels of UV radiation reaching Earth, higher skin cancer rates, and impact on crops. Examples: Antarctic Ozone Hole.
Coral Reef Bleaching
Consequences: Loss of marine habitats, reduced biodiversity, and decline in fishery resources. Examples: Great Barrier Reef (Australia), Coral Triangle (Asia-Pacific).
Sand Mining
Consequences: Ecosystem destruction, eroded beaches and dunes, and infrastructure damage due to sediment deficit. Examples: Mekong Delta degradation (Vietnam), Illegal sand trade.
Glacier Retreat
Consequences: Sea-level rise, loss of freshwater supplies and climate patterns alteration. Examples: Melting of Greenland ice sheet, retreating Himalayan glaciers.
Wetland Destruction
Consequences: Loss of flood mitigation, reduction of water quality, and habitat loss. Examples: Florida Everglades, Mesopotamian Marshlands (Iraq).
