Study Notes
Introduction to Environmental Science
- Environmental science integrates knowledge from biology, chemistry, physics, geography, and economics to understand environmental problems.
- It studies interactions between human activities and the natural world, impacting ecosystems, biodiversity, and human health.
Key Environmental Issues
- Climate change: Greenhouse gas emissions cause rising temperatures, altered weather, and sea-level rise, disrupting ecosystems and societies.
- Biodiversity loss: Species extinction rates increase due to habitat loss, pollution, and climate change, impacting ecosystem services and human well-being.
- Pollution: Air, water, and soil pollution from industries, agriculture, and transportation harms human health and the environment. Air pollution causes respiratory issues and acid rain, water pollution contaminates drinking water and harms aquatic life, and soil pollution affects plant growth and food chains.
- Resource depletion: Overuse of water, minerals, and forests threatens availability and ecosystem health.
- Population growth: Increasing human populations strain resources, causing environmental degradation and conflict.
Key Concepts in Environmental Science
- Sustainability: Balancing human needs with environmental well-being for present and future generations. It involves conserving resources, reducing pollution, and responsible consumption.
- Carrying capacity: The maximum population size a species can sustainably support. Exceeding this capacity causes environmental degradation.
- Ecosystem services: Essential benefits ecosystems provide, such as clean air and water, pollination, climate regulation, and nutrient cycling.
Environmental Ethics
- Understanding moral responsibilities to the environment and nature. Should humans prioritize resource exploitation or consider ecosystems' well-being?
- Different philosophical perspectives exist, like deep ecology, ecological feminism, and environmental justice.
Environmental Policy and Law
- Government regulations address environmental issues and promote sustainability, dealing with pollution, conservation, and resource management.
- International cooperation and treaties tackle global environmental problems.
Environmental Management and Conservation
- Strategies protect and restore ecosystems. They include habitat restoration, species conservation, and protected area management.
- Sustainable practices in agriculture, forestry, fisheries, and urban planning affect human-environment interactions.
- Environmental monitoring and assessment track changes and evaluate intervention effectiveness.
Types of Pollution
- Air pollution: Release of harmful substances into the atmosphere (e.g., gases, particulates).
- Water pollution: Contamination of water bodies (e.g., lakes, rivers, oceans) by pollutants (e.g., chemicals, sewage, agricultural runoff).
- Land pollution: Soil degradation from pollutants (e.g., industrial activities, improper waste disposal, agricultural practices).
Types of Ecosystems
- Forests: Contribute to oxygen production, carbon sequestration, and biodiversity conservation.
- Freshwater ecosystems: Essential for drinking water, agriculture, and aquatic life.
- Marine ecosystems: Support diverse species and provide resources like fish and seafood.
Human Impact on the Environment
- Deforestation
- Agriculture
- Industrialization
- Urbanization
- Transportation
- Waste generation
