Study Notes

Overview of Environmental Science

Environmental science studies interactions between humans and the natural environment.
Encompasses both living (plants, animals, fungi) and non-living (rocks, soil, water) elements.
Involves the built environment (cities, buildings) and social institutions.

Importance of the Environment to Humans

Climate, air and water quality, soil types, and the presence of other organisms are crucial for human survival.
Environmental conditions impact human health, wealth, and mobility.
The health of our planet is vital for long-term survival and well-being.

Interdisciplinary Nature of Environmental Science

Combines concepts from multiple fields:
- Economics: Evaluates energy sources (e.g., coal) and their costs.
- Geology: Involves mining practices and land use.
- Engineering: Focuses on the infrastructure needed for energy distribution.
- Chemistry: Studies pollution effects from energy generation.
- Meteorology: Analyzes weather impacts, like acid rain.
- Ecology: Examines the relationship between pollution and plant health.
- Politics: Involves regulations and laws for environmental protection.

Natural Resources

Are essential for human survival and include:
- Renewable Resources: Continuously available (sunlight, wind) and renew over short periods (water, soil, timber).
- Non-renewable Resources: Finite and can be depleted (oil, coal, minerals).

Global Human Population Growth

Global population exceeds 6.7 billion due to:
- Agricultural and industrial revolutions.
- Urbanization and advancements in sanitation and medicine.
Overpopulation leads to resource depletion and environmental degradation.

The Ecological Footprint

Measures the biologically productive land and water needed for resources and waste disposal.
"Overshoot" occurs when humanity exceeds the Earth's capacity to sustain itself, utilizing 30% more resources than sustainably available.

Role of Environmentalism

Environmentalism is a movement aimed at protecting the natural environment.
Ethical pursuit of knowledge about environmental issues and promoting activism for sustainability.

The Nature of Science

Science employs a systematic method for learning and testing knowledge about the world.
Critical for discerning facts from fiction and developing solutions for environmental challenges.

Scientific Method in Environmental Science

Steps:
- Define the problem/question.
- Formulate hypotheses as potential solutions.
- Collect data (qualitative and quantitative).
- Test hypotheses through observation and experimentation.

Levels of Ecology

Species: Groups of similar organisms capable of interbreeding.
Population: Groups of the same species in a specific area over time.
Community: Groups of different populations interacting in a defined area.

Conclusion

Humans’ well-being is inextricably linked to environmental quality.
Sustainable practices and informed decision-making are vital for future generations.
