Study Notes
Environmental Pollution and Energy Sources
- Hazardous noise pollution begins at sound levels above 100 decibels, causing potential health risks.
- Renewable energy sources include wind power, crucial for sustainable energy solutions.
- Solar energy is also a prominent renewable energy source, harnessing sunlight for power.
Notable Movements and Individuals
- The Chipko Movement, advocating for forest conservation, was led by Sundar Lal Bahuguna.
Photosynthesis and Ecosystem Components
- Photosynthesis requires carbon dioxide, a key element in the process of converting sunlight to energy.
- The biosphere comprises three major spheres: lithosphere (land), hydrosphere (water), and atmosphere (air).
Global Environmental Events
- The Earth Summit, a significant conference focused on global environmental issues, was held in Rio de Janeiro.
- World Environment Day is celebrated annually on June 5th to promote environmental awareness and action.
Environmental Issues and Legislative Actions
- Acid rain results from air pollution, affecting water sources and ecosystems.
- The Environmental Protection Act was enacted in 1986 to regulate pollution and protect the environment.
Health and Environmental Interactions
- Hemoglobin, the oxygen-carrying component in blood, has a high affinity for carbon monoxide, which can be deadly.
Historical Environmental Disasters
- The Bhopal gas disaster, one of the worst industrial disasters, occurred in 1984, highlighting the dangers of chemical safety.
Ecological Concepts
- The ecological pyramid, specifically the pyramid of energy, is always upright, illustrating energy transfer in ecosystems.
- Forests and wildlife can be considered renewable resources when managed wisely to ensure sustainability.
Agricultural Practices and Soil Issues
- Eco-friendly agricultural practices include using organic fertilizers and bio-pesticides to reduce chemical impacts.
- Soil erosion negatively impacts the storage capacity of dams, reduces soil fertility, and can lead to desertification.
Earth’s Spheres and Environmental Function
- The hydrosphere refers to the layer of water covering the Earth's surface, essential for all life.
- The stratosphere is the atmospheric layer that absorbs harmful ultraviolet (UV) radiation from the sun.
Ecology and Environmental Management
- Ecology is the study of how organisms interact with their environment, essential for understanding ecosystem dynamics.
- Extensive tree planting supports ecosystem balance, promotes ecotourism, and alleviates pressure on natural forests.
