Study Notes
What is the Environment and What is an Ecosystem?
- The environment consists of all living and nonliving things supporting life on Earth.
- A system is a collection of interacting components that produce patterns of behavior over time.
- An ecosystem is a natural system composed of living and nonliving components, such as a coral reef.
- Humans rely on ecosystem services, such as oxygen, water, and energy, for survival.
- The Anthropocene Epoch is characterized by significant human impacts on the planet.
What is Sustainability?
- Sustainable development aims to meet current needs without compromising future generations' abilities to meet theirs.
- Sustainability involves managing natural resources to ensure their long-term availability.
- Sustainability encompasses environmental, economic, and social aspects, often referred to as the 3Es.
- The UN has outlined 17 sustainable development goals (SDGs), each with indicators to measure progress.
- Climate change is a significant environmental challenge addressed by the SDGs.
- Ecological resilience refers to an ecosystem's ability to recover from disruptions like wildfires or overfishing.
What is Science?
- Science is a process of asking and answering questions about the natural world.
- The scientific method involves observation, hypothesis formulation, controlled experimentation, and data analysis.
- A hypothesis is a proposed explanation for a phenomenon or answer to a scientific question.
- Controlled experiments compare manipulated and unmanipulated situations to isolate the effects of a specific variable.
- Reproducibility and public sharing of scientific findings are essential for validation.
- Models are simplified representations of complex processes used to understand natural phenomena.
What Shapes Our Decisions on the Environment?
- Ecological footprint analysis measures the amount of natural resources needed to support a particular lifestyle.
- Carbon footprints estimate the level of greenhouse gas emissions associated with a particular activity.
- Countries with the largest ecological footprints are those with high consumption rates.
- Collaboration and collective action within social networks can amplify individuals' influence on environmental issues.
