Match the following environmental issues with their causes:
Match the following environmental issues with their causes:
Ozone depletion = CFCs from spray cans, refrigerators, and industrial detergents Eutrophication = High levels of nitrogen and phosphorus from animal slurry Vermin and odours at waste disposal sites = Waste attracting rats and gulls Groundwater contamination from waste disposal = Unsuitable items left at dumps
Match the following environmental problems with their solutions:
Match the following environmental problems with their solutions:
Overfishing = Setting fish quotas Pollution in fisheries = Reducing pollution to allow migratory fish to reach breeding grounds Contamination of groundwater from waste disposal = Preventing unsuitable items from being left at dumps Ozone depletion = Reduction in use of CFCs and using HFCs instead
Match the following waste management practices with their importance:
Match the following waste management practices with their importance:
Bioremediation = Removing pollution and allowing areas to revert to their unpolluted state Waste minimisation = Conserving resources by reducing waste at the source Slurry management = Improving water quality by controlling the release of nutrients into rivers and lakes Microorganisms in waste management = Breaking down organic waste and destroying pathogens

Study Notes
Environmental Issues and Their Causes
- Climate Change: Caused by greenhouse gas emissions from fossil fuel combustion, deforestation, and industrial processes.
- Air Pollution: Resulting from vehicle emissions, industrial discharges, and burning of biomass.
- Water Pollution: Caused by agricultural runoff, industrial waste dumping, and sewage discharge.
- Deforestation: Driven by agricultural expansion, logging, and urbanization.
Environmental Problems and Their Solutions
- Ocean Acidification: Solution includes reducing carbon emissions and promoting marine conservation.
- Plastic Pollution: Reduce usage through biodegradable alternatives and enhance recycling programs.
- Biodiversity Loss: Solutions involve habitat restoration and the establishment of protected areas.
- Soil Degradation: Implement sustainable farming practices and promote organic agriculture.
Waste Management Practices and Their Importance
- Recycling: Reduces waste in landfills and conserves natural resources by reprocessing materials.
- Composting: Reduces organic waste and produces nutrient-rich soil, enhancing soil health.
- Incineration: Diminishes the volume of waste and can generate energy but must manage emissions properly.
- Landfilling: Last resort for waste disposal, requiring careful monitoring to prevent soil and water contamination.
Human Activities and Resulting Environmental Issues
- Urbanization: Leads to habitat destruction and increased pollution levels.
- Agricultural Practices: Can cause soil erosion, water scarcity, and chemical runoff into waterways.
- Industrialization: Contributes to air and water pollution, along with habitat destruction.
- Deforestation for Agriculture: Results in loss of biodiversity and increased carbon emissions.
Types of Pollutants and Their Sources
- Heavy Metals: Common sources include mining, industrial discharge, and waste incineration.
- Nutrients (Nitrogen and Phosphorus): Primarily derived from fertilizers, agricultural runoff, and sewage.
- Particulate Matter: Released from vehicles, industrial activities, and combustion of fossil fuels.
- Plastics: Originates from packaging waste, improper disposal, and industrial manufacturing processes.
Environmental Impacts and Their Causes
- Coral Bleaching: Caused by rising ocean temperatures and acidification from atmospheric CO2 increase.
- Loss of Arctic Ice: Resulting from global warming through greenhouse gas emissions.
- Increased Flooding: Linked to deforestation, urbanization, and climate change.
- Declining Fish Stocks: Resulting from overfishing, habitat destruction, and pollution.
Ecosystems and Affected Elements of Pollution
- Marine Ecosystems: Affected by plastic waste, oil spills, and nutrient runoff leading to eutrophication.
- Freshwater Ecosystems: Impacted by agricultural runoff, sewage discharge, and industrial pollution.
- Terrestrial Ecosystems: Pollution from chemicals, heavy metals, and waste affecting soil health and species.
- Wetland Ecosystems: Threatened by water pollution, habitat loss, and climate change effects.
