Study Notes
Malnutrition
- Malnutrition is characterized by not getting enough to eat, living with chronic hunger, and poor nutrition.
- It is not a result of eating a healthy diet.
- Lack of motivation to eat is not a characteristic of malnutrition.
Overnutrition
- Overnutrition is when food energy intake exceeds energy expenditure, leading to excess body fat.
- Overnutrition results in a lower life expectancy and increased susceptibility to disease.
- Lower productivity and quality of life are also associated with overnutrition.
- Living healthily is not indicative of overnutrition.
Types of Agriculture
- Industrialized agriculture aims to yield more food per unit of land, relying on heavy machinery, significant financial capital, fossil fuels, water, commercial fertilizers, and pesticides to cultivate monocultures.
- Traditional agriculture is a less intensive agricultural approach compared to industrialized agriculture.
- Systematic agriculture is not a defined type of agriculture.
- Regular agriculture is not a defined category of agriculture.
Genetic Engineering
- Genetic engineering involves altering an organism's genetic material to create desirable traits and eliminate undesirable traits through adding, deleting, or changing segments of its DNA.
- Gene splicing is a method used in genetic engineering to produce crop varieties faster.
Industrialized Food Production and Energy
- Industrialized food production requires substantial energy inputs for running farm machinery, producing synthetic pesticides and fertilizers, and transporting food across countries.
Environmental Effects of Food Production
- Overproduction of food leads to increased food waste.
- Cultivated areas replace natural ecosystems like grasslands, forests, and wetlands.
- Cultivated areas have a loss of genetic diversity in crop strains as they are solely focused on monoculture farming.
- Killing wild animal predators to protect livestock is an unintended consequence of specific farming practices.
Soil Degradation
- Salinization occurs when repeated irrigation applications in dry climates cause salts to accumulate in upper soil layers.
Irrigation Effects
- Excessive irrigation depletes groundwater and surface water supplies.
- Excessive irrigation leads to waterlogging, increasing the water table.
- Excessive irrigation can reduce soil fertility due to the depletion of plant nutrients.
Genetically Modified Organisms (GMOs)
- Critics of GMOs are concerned about their potential for long-term harm to human health and ecosystems, possible harmful genetic and ecological effects, and the potential for these genes to spread between species and decrease natural genetic biodiversity in crops.
Water Resources Management
- Poor management of water resources leads to issues like falling water tables, disappearing wetlands, swelling of lakes, and decreasing river flows in areas with intensive water use.
Water Use
- Fresh water is used globally for manufacturing goods, wastewater disposal, irrigation, drinking, bathing, growing crops, and generating power and in residential, agricultural, and industrial uses.
Water Resources
- Ninety-seven percent of the world's water resources are saltwater.
- Eighty percent of the remaining water is found in ice caps and glaciers.
Groundwater Pollution
- Polluted groundwater is difficult and costly to clean up due to the extended time it takes for groundwater to recycle, pollutants clinging to the aquifer, and the vast areas of rock and dispersed pollutants throughout.
Aquifer Overpumping
- Overpumping aquifers limits future food production, exacerbates the gap between the rich and poor, and can cause land to collapse due to subsidence and sinkholes.
Desalination
- Desalination technologies involve processes like vapor-compression evaporation, thermal distillation, membrane distillation, and reverse osmosis.
- These technologies are used to remove salt from ocean or brackish water, creating freshwater.
- Desalination is costly, creates brine waste, increases fossil fuel dependence, greenhouse gas emissions and exacerbates climate change when non-renewable resources are utilized for freshwater production.
Flood Disadvantages
- Floods cause property destruction and loss of life, despite having a positive role in nutrient deposition for healthy fisheries and recharging groundwater for biodiversity.
Wastewater Reduction
- Wastewater can be reduced through several methods, such as using drip irrigation and mulch for gardens, repairing water leaks, using recycled water for lawns and plants, and encouraging water-efficient crops.
Mining Impacts
- Mining results in environmental impacts including creating dust, destruction of natural habitats, groundwater pollution, and soil erosion.
Rock Classification
- Geologists classify rocks into sedimentary, igneous, and metamorphic rocks based on their formation.
