Study Notes
Sustainable Development
- Defined by the World Commission on Environment and Development (WCED) as development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
- Key aspects of achieving sustainability include:
- Circulating and reusing materials
- Reducing material usage
- Protecting living organisms by minimizing harmful substances
- Minimizing energy use and waste heat
- Creating long-lasting products
- Utilizing sustainable energy sources
- Conserving resources
- Learning from nature for sustainable living
Sustainable Development Goals (SDGs)
- The 2030 Agenda for Sustainable Development adopted by all UN members outlines 17 SDGs.
- These goals address climate change, ocean and forest conservation, global peace, and inclusive societies.
- All countries and stakeholders are expected to implement this plan.
Areas of Critical Importance (5 Ps)
- People: End poverty and hunger, ensure equality
- Planet: Protect the planet from degradation
- Prosperity: Enable all humans to enjoy fulfilling lives
- Peace: Foster peaceful and inclusive societies free from fear and violence
- Partnership: Global solidarity focused on the needs of the most vulnerable
Relationship Between Poverty and Environmental Problems
- Poverty poses a significant threat to human health and the environment.
- Those living in poverty often lack the luxury of prioritizing long-term environmental sustainability.
Environmentally Sustainable Society
- A society fulfilling its people's basic needs without depleting natural resources.
- This involves meeting current needs for resources such as wood, water, clean air, and shelter while living off natural income replenished by the environment.
Sustainable Living
- Current unsustainable practices are depleting the Earth's natural capital at an alarming rate.
Reducing Water Pollution
- Practical steps to reduce water pollution include:
- Utilizing manure instead of commercial fertilizer
- Minimizing pesticide use
- Preventing yard waste from entering drains
- Avoiding toilet fresheners and flushing unwanted medicine
- Refraining from pouring harmful pesticides down the drain
Soil Contamination
- The upper layer of the Earth's crust is transformed by weathering and biological processes, forming soil.
- Soil pollution occurs when a chemical or substance is present at higher than normal concentrations.
Main Sources of Soil Pollution
-
Anthropogenic sources dominate:
- Point-source Pollution: Specific events releasing contaminants into the soil, easily identified (e.g., factory sites, spills).
- Diffuse Soil Pollution: Pollutants spread over wide areas, difficult to track and analyze (e.g., air-soil-water systems).
- Natural Geogenic Sources: Include volcanic releases, weathering of minerals, and natural events such as eruptions or fires.
-
Anthropogenic Sources:
- Industrial Activities: Release harmful chemicals, wastes, and wastewater.
- Mining: Releases significant amounts of heavy metals and toxic elements.
- Waste and Sewage: Growing populations generate more waste, requiring careful management.
Waste Management
-
Canadian Waste Statistics (2021):
- Average Canadian generates 777 kg of waste annually.
- Municipal solid waste diversion rate: 25%.
- Waste management costs: $2.6 billion.
- E-waste generated annually: 725,000 tons.
-
Global E-waste (2021):
- 57.4 million tons of e-waste generated globally.
- Average individual generates 7 kg of e-waste.
The Meaning of a High-Waste Society
- Characterized by a "throwaway mentality", where separating valuable resources in landfills is difficult.
- Limited consideration for human and environmental safety.
Waste Reduction
- Treating solid waste as potential resources for reuse.
- Prioritizing waste reduction strategies.
Options for Solid Waste Management
-
Primary Pollution and Waste Prevention (1st Priority):
- Change industrial processes, refuse harmful products, minimize waste, reduce packaging.
- Reuse and Repair, Recycle, Compost (2nd Priority):
- Treat Waste to Reduce Toxicity, Landfill Burial, Incineration (Last Priority):
-
Refuse, Reduce, Reuse, Recycle, Rethink, Recover:
- Refusing unnecessary products, reducing packaging, reusing materials, recycling products, rethinking strategies, and recovering valuable materials.
Industrial Ecology
- Mimicking natural systems for waste management.
- Transforming resource-to-waste systems into recycling systems.
Air Pollution
- The Atmosphere:
- Composed of layers with varying temperatures, pressures, and compositions.
Types of Air Pollution
- Primary Pollutants: Released directly into the atmosphere (e.g., smoke).
- Secondary Pollutants: Formed in the atmosphere through chemical reactions (e.g., ozone).
Sources of Air Pollution
- Natural Sources: Volcanic emissions, forest fires, dust storms.
- Anthropogenic Sources: Combustion of fossil fuels, industrial processes, vehicular emissions.
Impact of Air Pollution
- Health problems: Respiratory illnesses, cardiovascular disease.
- Environmental damage: Acid rain, smog, climate change.
Noise Pollution
- Sound levels exceeding acceptable limits, causing discomfort, stress, and health issues.
Sources of Noise Pollution
- Traffic, construction, industrial activities, machinery, loud music.
Impact of Noise Pollution
- Sleep disturbance, stress, hearing loss, cardiovascular problems, reduced productivity.
Noise Control
- Source control, path control, receiver control, and land-use planning.
Light Pollution
- Artificial light exceeding natural nighttime levels, causing glare, skyglow, and light trespass.
Types of Light Pollution
- Glare: Excessive brightness causing visual discomfort.
- Skyglow: Brightening of the night sky over inhabited areas.
- Light Trespass: Light falling where it is not intended or needed.
- Clutter: Bright, confusing, and excessive groupings of light sources.
Causes of Light Pollution
- Street and vehicle lighting, advertising lights, industrial lights.
Impacts of Light Pollution
- Wasteful energy and money: Inefficient lighting leads to wasted resources.
- Environmental degradation: Impacts wildlife, alters plant growth, reduces star visibility.
- Human health issues: Sleep disturbances, hormonal imbalances.
Reducing Light Pollution
- Using low-voltage, warm-colored lights, shielding lights to direct them downward, utilizing motion sensors, turning off unnecessary lights, and advocating for environmentally responsible lighting regulations.
