Back

Humans influence biogeochemical cycles through activities such as pollution, deforestation, and agriculture, which alter the natural flow of nutrients and energy. (carbon, water and nitrogen)

Front

Back

Renewable resources: solar energy, wind energy, water. Nonrenewable resources: fossil fuels, minerals, nuclear energy.

Front

What are the goals of each type of technology, and what is one positive and one negative outcome for each?

Back

Goal of renewable technology: sustainability; positive outcome: reduced emissions; negative outcome: high initial costs. Goal of nonrenewable technology: energy production; positive outcome: high energy output; negative outcome: environmental degradation.

Front

Front

List three ways humans threaten biodiversity.

Back

Front

How have humans influenced the environment?

Back

Through industrialization, urbanization, and resource exploitation, leading to climate change and habitat loss.

Front

What is sustainability?

Back

Sustainability is the ability to meet present needs without compromising the ability of future generations to meet their own needs.

Front

What is the ecological (carbon) footprint?

Back

The ecological footprint measures the environmental impact of an individual or community in terms of the amount of land and water required to sustain their resource consumption and waste.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

What are invasive species?

Back

Invasive species are non-native organisms that spread widely in a new habitat, often causing harm to native species and ecosystems.
