- 2. Topic Outline: Definition, Scope,and Importance of Environmental Science Field of Environmental Science Environmental Interrelationships Ecology and Environmental Science Unifying Environmental Themes Source: https://www.worldatlas.com/rivers/amazon-river.html
- 3. Derived from theGreek word “environner”, which means to encircle around or surround. Environment Protection Act 1986: The sum total of land, water, air, interrelationships among themselves and also with living organisms. Definition, Scope, and Importance of Environmental Science Definition of Environment
- 4. Scope of Environment Protectsthe Earth’s surface Regulates the Earth’s temperature Atmosphere Hydrosphere All types of water resources Lithosphere Outer mantle of the Earth Biosphere Realm of living organisms and their interactions with the environment Definition, Scope, and Importance of Environmental Science
- 5. Environmental Science It isan interdisciplinary field that studies the interactions between the natural environment and human society. Deals with ecology, geology, atmospheric science, hydrology, oceanography, etc.
- 6. Importance of EnvironmentalScience Provide basic knowledge of the environment to all individuals and help in understanding present environmental projects. Provide a more sustainable way of living. Helps in using natural resources more efficiently. Educating and making people aware of different environmental issues and problems.
- 7. 5 Major Fieldsof Environmental Science Deal with global warming and its effect Atmospheric Sciences Ecologists Research Deals with how a specific species or a group of living creatures are influenced by their environment Environmental Chemistry Explores things like chemical effects on different plants Social Sciences Deal with the relationship between humans and nature Explore the chemical and physical constitution of our planet Geosciences
- 8. Environmental Interrelationships It refers tothe complex and interconnected relationships that exist among various elements within the natural world. These relationships are fundamental to understanding how ecosystems function and how human activities can impact the environment.
- 9. Ecology • Is thescientific study of the relationships between organisms and their environment. • Environment includes the physical and chemical conditions as well as the biological or living components of an organism’s surroundings. • Relationships include interactions with the physical world as well as with members of the same and other species. Ecology and Environmental Science
- 10. Levels of Ecology SpeciesPopulation Community Ecosystem Biosphere
- 11. Is a resourcethat can be replenished naturally over time. Examples: Forests, grasslands, freshwater, fertile soil, and air Renewable Resources Non-Renewable Resources Refers to a natural substance that is not replenished with the speed at which it is consumed. Examples: Coal, oil, copper, aluminum, salt, and sand Ecological Footprint -measures demand on nature including consumption of resources and emissions.
- 12. is the totalamount of greenhouse gas emissions that come from the production, use and end- of-life of a product or service. Ecological Footprint Carbon Footprint Solid Waste By 2050, worldwide municipal solid waste generation is expected to have increased by roughly 70 percent to 3.4 billion metric tons. Mining Large-scale mining can contribute to deforestation and biodiversity loss.
- 14. Unifying Environmental Themes: Interdependence refersto the intricate connections and mutual reliance among different elements within an ecosystem, where changes in one component can affect others.
- 15. Diversity and StabilityChange Unifying Environmental Themes: ecosystems with a wide variety of species are more resilient and better equipped to handle disturbances and changes over time.
- 16. Balance of Nature UnifyingEnvironmental Themes: ecosystems tend to naturally self-regulate and maintain a harmonious equilibrium, although this equilibrium can be disrupted by human activities.
- 17. Finiteness of Resources UnifyingEnvironmental Themes: highlights the idea that natural resources, such as minerals and fossil fuels, are limited in quantity and must be managed carefully to prevent depletion.
- 18. Material Cycles Unifying EnvironmentalThemes: involve the continuous flow and recycling of essential elements and compounds (e.g., carbon, nitrogen, water) through natural processes within ecosystems.
- 19. Population Growth andCarrying Capacity Unifying Environmental Themes: examines how the size of a population, particularly human populations, interacts with the environment's ability to support it without resource exhaustion.
- 20. Stewardship Unifying Environmental Themes: entailsresponsible and ethical management of natural resources and ecosystems to ensure their preservation and sustainable use.
- 21. Unifying Environmental Themes: SustainableDevelopment • Renewable Energy • Crop Rotation • Waste Management • Reduced greenhouse gases • Sustainable Forestry
