Study Notes
Environment
Climate Change
- Global temperatures rising by 1°C since 1880
- Main causes: greenhouse gas emissions (CO2, methane, etc.) from human activities (burning fossil fuels, deforestation, etc.)
- Consequences: more frequent and severe weather events, sea-level rise, melting of polar ice caps
Biodiversity Loss
- Current rate of species extinction: 100-1,000 times faster than natural rate
- Causes: habitat destruction, pollution, climate change, overfishing, etc.
- Consequences: ecosystem disruption, loss of ecosystem services, reduced food security
Plastic Pollution
- 8 million tons of plastic waste enter oceans annually
- Causes: single-use plastics, inadequate waste management, littering
- Consequences: harm to marine life, contamination of food chain, economic impacts
Deforestation and Land Degradation
- 13 million hectares of forest lost annually
- Causes: agriculture, urbanization, logging, etc.
- Consequences: loss of biodiversity, increased greenhouse gas emissions, soil erosion
Sustainable Development
- 17 UN Sustainable Development Goals (SDGs) aim to balance human well-being with environmental protection
- Key goals: climate action, life below water, life on land, sustainable cities and communities
- Achieving SDGs requires international cooperation, policy changes, and individual actions
Renewable Energy and Energy Transition
- Renewable energy sources: solar, wind, hydro, geothermal, etc.
- Benefits: reduced greenhouse gas emissions, energy independence, job creation
- Challenges: intermittency, infrastructure costs, policy and regulatory frameworks
Water Scarcity and Management
- 2 billion people live in water-scarce areas
- Causes: climate change, population growth, inefficient use, pollution
- Consequences: food insecurity, economic impacts, human health risks
- Solutions: water conservation, efficient use, sustainable agriculture practices
Environment
Climate Change
- Global temperatures have risen by 1°C since 1880
- Greenhouse gas emissions, primarily from human activities, are the main cause of climate change
- Burning fossil fuels and deforestation are significant contributors to greenhouse gas emissions
- Climate change consequences include:
- More frequent and severe weather events
- Sea-level rise
- Melting of polar ice caps
Biodiversity Loss
- The current rate of species extinction is 100-1,000 times faster than the natural rate
- Habitat destruction, pollution, climate change, and overfishing are key causes of biodiversity loss
- Consequences of biodiversity loss include:
- Ecosystem disruption
- Loss of ecosystem services
- Reduced food security
Plastic Pollution
- Approximately 8 million tons of plastic waste enter oceans annually
- Single-use plastics, inadequate waste management, and littering are primary causes of plastic pollution
- Consequences of plastic pollution include:
- Harm to marine life
- Contamination of the food chain
- Economic impacts
Deforestation and Land Degradation
- Approximately 13 million hectares of forest are lost annually
- Agriculture, urbanization, and logging are primary causes of deforestation and land degradation
- Consequences of deforestation and land degradation include:
- Loss of biodiversity
- Increased greenhouse gas emissions
- Soil erosion
Sustainable Development
- The 17 UN Sustainable Development Goals (SDGs) aim to balance human well-being with environmental protection
- Key SDGs include:
- Climate action
- Life below water
- Life on land
- Sustainable cities and communities
