Key Concepts 

  1. Pollution: The introduction of harmful substances or products into the environment, leading to negative effects on health, ecosystems, and the climate.
  2. Sustainable Development: Development that meets current needs without compromising the ability of future generations to meet their own needs, balancing economic growth with environmental protection.
  3. Environmental Impact Assessment (EIA): A process used to evaluate the potential environmental effects of a proposed project or development before it is carried out.
  4. Waste Management: The collection, transportation, processing, recycling, or disposal of waste materials, aiming to reduce environmental harm.
  5. Pollution Control Technologies: Methods and tools used to prevent or reduce the release of pollutants into the environment, such as filtration systems, wastewater treatment plants, and renewable energy sources.
  6. Emission Standards: Regulations that set the maximum allowable levels of pollutants that can be emitted into the air, water, or soil from industrial and other sources.
  7. Pollution Prevention (P2): Measures taken to reduce or eliminate the generation of pollutants at the source, before they can cause harm to the environment.
  8. Renewable Energy: Energy sourced from renewable sources, such as wind, solar, and hydroelectric, that reduce dependency on fossil fuels and lower pollution levels.

Key Terms

  • Air Quality Index (AQI): A measure used to communicate the quality of air in a specific location based on pollutant levels.
  • Biodegradable: Substances that can be broken down by natural processes, such as bacteria, fungi, or other organisms.
  • Carbon Footprint: The amount of carbon dioxide emissions produced by human activities, typically measured in tons per year.
  • Greenhouse Gases (GHGs): Gases in the Earth’s atmosphere that trap heat, contributing to global warming (e.g., CO2, methane).
  • Recycling: The process of converting waste materials into new products, reducing the need for raw materials and decreasing pollution.
