Environmental Science Concepts

Front

Ecosystem

Back

A biological community of interacting organisms and their physical environment. It includes both living and non-living components.

Front

Biodiversity

Back

The variety of plant and animal life in a particular habitat or in the world as a whole. High biodiversity is essential for maintaining ecosystem health.

Front

Sustainability

Back

The practice of using resources in a way that meets current needs without compromising the ability of future generations to meet theirs.

Front

Climate Change

Back

Long-term changes in temperature, precipitation, wind patterns, and other elements of the Earth's climate system, largely driven by human activities.

Front

Deforestation

Back

The large-scale removal of forests, often for agriculture or urban development, which negatively impacts biodiversity and contributes to climate change.

Front

Renewable Energy

Back

Energy that comes from resources which are naturally replenished, such as sunlight, wind, and water. It contrasts with fossil fuels, which take millions of years to form.

Front

Carbon Footprint

Back

The total amount of greenhouse gases (including carbon dioxide and methane) generated by our actions, commonly measured in tons of CO2.

Front

Pollution

Back

The introduction of harmful substances or products into the environment, which can affect air, water, and land, leading to negative impacts on health and ecosystems.

Front

Greenhouse Effect

Back

The trapping of the sun’s heat in the Earth’s lower atmosphere due to the presence of greenhouse gases, leading to a warming effect that contributes to global warming.

Front

Conservation

Back

The protection and preservation of natural environments and wildlife, often through efforts to manage resources and habitats sustainably.
