Study Notes
Introduction to Environmental Science
- Environmental science is the systematic study of our environment and our role within it.
- It combines natural sciences, social sciences, and humanities to understand the world around us.
- It is interdisciplinary, drawing on fields such as ecology, chemistry, urban planning, sociology, political science, engineering, and economics.
History of Environmentalism
- The history of environmentalism can be traced back to the Industrial Revolution, marked by increased pollution and chemical discharges.
- Early environmental movements focused on combating air pollution and advocating for cleaner air.
- The modern environmental movement gained momentum in the 1960s and 1970s, driven by concerns about environmental degradation and the impact of industrialization.
- The environmental justice movement emerged in the 1980s to address social and economic inequalities linked to environmental issues, particularly in low-income communities.
- Key conferences and protocols like the Stockholm Conference (1972), the Montreal Protocol (1987), and the Earth Summit (1992) aimed to address global environmental concerns.
Environmental Ethics
- Environmental ethics examines the moral relationship between humans and the environment, exploring the value and ethical status of nonhuman elements.
- It focuses on expanding the scope of moral consideration and ethical concern to include a wider range of entities, groups, or issues.
- The concept of ethical extension is crucial, highlighting the importance of recognizing the moral status of nonhuman beings.
- Public awareness of animal sentience, like the study in Science (2004) regarding fish and pain, has spurred ethical debates.
Principles of Environmental Ethics
- Profound respect for nature
- Maintain a harmonious relationship with other species
- Take responsibility for the impact on nature
- Respect for local and indigenous environmental knowledge
- Plan for the long term
Matter, Energy, and Life
- Matter is anything that occupies space and has mass.
- The law of conservation of matter is essential for understanding our relationship with the biosphere, as matter cannot be created or destroyed.
Laws of thermodynamics
- The first law of thermodynamics states that energy is conserved, meaning it cannot be created or destroyed.
- The second law of thermodynamics states that with each energy transfer or transformation, less energy is available for work.
Ecological Organization
- A population consists of all members of a species living in a given area at the same time.
- An ecosystem encompasses a biological community and its physical environment.
Energy Flow Through the Ecosystem
- Sunlight is the primary energy source for ecosystems.
- Plants (producers) convert sunlight into energy-storing biomolecules through photosynthesis.
- Consumers (animals) obtain energy by eating plants or other animals.
- Decomposers break down dead organisms, recycling matter and nutrients.
- Energy flow is unidirectional, moving from light to heat and cannot be recycled.
- The concept of ecological pyramids illustrates the inefficient energy transfer that occurs in food chains.
