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.
