Study Notes
Air Pollution
- Definition: Presence of harmful substances in the atmosphere.
-
Sources:
- Vehicle emissions
- Industrial discharges
- Burning of fossil fuels
-
Effects:
- Respiratory diseases (asthma, lung cancer)
- Cardiovascular problems
- Climate change (greenhouse gas emissions)
- Ozone layer depletion
Water Contamination
- Definition: Introduction of harmful chemicals or pathogens into water bodies.
-
Sources:
- Industrial waste disposal
- Agricultural runoff (pesticides and fertilizers)
- Sewage and wastewater discharge
-
Effects:
- Drinking water shortages
- Aquatic ecosystem disruption
- Spread of waterborne diseases (cholera, dysentery)
- Bioaccumulation in food chains
Soil Degradation
- Definition: Deterioration of soil quality and productivity.
-
Sources:
- Overuse of chemical fertilizers and pesticides
- Deforestation and land clearing
- Overgrazing by livestock
-
Effects:
- Reduced agricultural productivity
- Loss of soil fertility and structure
- Increased erosion
- Contamination of groundwater
Health Impacts
-
Direct Health Effects:
- Respiratory diseases from air pollutants
- Gastrointestinal illnesses from contaminated water
- Skin diseases from polluted soil
-
Long-term Effects:
- Increased risk of chronic conditions (cancer, heart disease)
- Developmental disorders in children
- Mental health issues linked to environmental stressors
-
Vulnerable Populations:
- Children
- Elderly individuals
- Low-income communities with limited access to clean environments
Biodiversity Loss
- Definition: Decrease in the variety and variability of life forms.
-
Causes:
- Habitat destruction due to urbanization and deforestation
- Pollution affecting species survival
- Climate change altering habitats
-
Effects:
- Ecosystem instability
- Loss of species essential for ecological balance
- Disruption of food chains
- Reduced resilience to environmental changes
Air Pollution
- Air pollution is the presence of harmful substances in the atmosphere.
- Major sources include vehicle emissions, industrial discharges, and burning fossil fuels.
- Effects include respiratory diseases like asthma and lung cancer, cardiovascular problems, climate change due to greenhouse gas emissions, and ozone layer depletion.
Water Contamination
- Water contamination occurs when harmful chemicals or pathogens enter water bodies.
- Sources include industrial waste disposal, agricultural runoff containing pesticides and fertilizers, and sewage and wastewater discharge.
- This can lead to drinking water shortages, aquatic ecosystem disruption, the spread of waterborne diseases like cholera and dysentery, and bioaccumulation of toxins in food chains.
Soil Degradation
- Soil degradation is the deterioration of soil quality and productivity.
- Causes include overuse of chemical fertilizers and pesticides, deforestation and land clearing, and overgrazing by livestock.
- Impacts include reduced agricultural productivity, loss of soil fertility and structure, increased erosion, and contamination of groundwater.
Health Impacts
- Air pollution causes respiratory diseases, contaminated water leads to gastrointestinal illnesses, and polluted soil can cause skin diseases.
- Long-term effects include increased risk of chronic conditions like cancer and heart disease, developmental disorders in children, and mental health issues linked to environmental stressors.
- Vulnerable populations include children, elderly individuals, and low-income communities with limited access to clean environments.
Biodiversity Loss
- Biodiversity loss refers to the decrease in the variety and variability of life forms.
- Causes include habitat destruction due to urbanization and deforestation, pollution affecting species survival, and climate change altering habitats.
- Effects include ecosystem instability, the loss of species essential for ecological balance, disruption of food chains, and reduced resilience to environmental changes.
