Study Notes
Understanding Our Environment
- Human beings inhabit two worlds: the natural world and the world of social institutions and artifacts created by humans.
Environmental Science
- Environmental science is the systematic study of our environment and our place in it.
- It is an interdisciplinary field that integrates natural science, social sciences, and humanities.
Sustainable Development
- Definition: meeting the needs of the present without compromising the ability of future generations to meet their needs.
Environmental Ethics
- The way we interpret environmental issues depends on our basic worldviews and decisions about natural resources.
Environmental Problems
- Clean Water: 1.1 billion people lack access to safe drinking water, and 2.5 billion lack modern sanitation, contributing to the ill health of 1.2 billion people annually.
- Food Supplies: global food production has kept pace with population growth, but soil degradation and biotechnology/ intensive farming techniques are concerns.
- Energy: fossil fuels provide 80% of energy used in industrialized countries, contributing to air and water pollution.
- Climate Change: human activities release CO2 and other gases, causing severe weather events, seasonal changes, droughts, floods, and ice disappearance.
- Air Pollution: worsened air quality causes 3 million deaths annually, with pollutants accumulating and being transported across thousands of kilometers.
- Biodiversity Loss: habitat destruction, overexploitation, pollution, and exotic species introduction threaten ecological life systems.
Signs of Hope
- Renewable Energy: China is making progress using wind, biogas generators, and solar collectors, with potential to get all energy from renewable sources.
- Health: many cities are becoming cleaner and more livable.
This quiz covers the basics of environmental science, exploring the natural world and its relationship with human-made institutions and artifacts.
