Invasive Species

Species that threaten biodiversity when introduced to a new environment.

CFCs

Gases that deplete the ozone layer, leading to increased UV radiation.

Fossil Fuels

Study Notes

Invasive Species

  • Invasive species pose a significant threat to biodiversity, disrupting ecosystems and displacing native species.

CFC Emissions

  • Factories emitting chlorofluorocarbons (CFCs) can lead to an increase in skin cancer rates due to ozone layer depletion.

Fossil Fuels

  • Unsustainable levels of fossil fuel usage include natural gas, coal, and oil, which cannot be renewed within a human timeframe.

Renewable Resources

  • Wood is classified as a renewable resource, as it can be replenished through sustainable forestry practices.

Greenhouse Effect

  • An increase in the greenhouse effect directly results in global warming, influencing climate patterns and weather events.

Air Pollution

  • Air pollution encompasses harmful substances like CFCs and smog, contributing to respiratory issues and environmental degradation.

Sustainable Practices

  • Sustainable use practices involve the responsible management of natural resources to avoid depletion and prevent environmental damage.

Natural Resource Requirements

  • As the human population expands, the demand for natural resources increases, putting additional pressure on the environment.
