All Flashcards
What is environmental sustainability?
Using resources wisely so future generations can enjoy them.
What is sustainable yield?
Amount of a resource harvested without reducing the base supply.
What are 'commons' in environmental terms?
Shared resources not owned by anyone (e.g., oceans, atmosphere).
Why is biological diversity important for sustainability?
Helps ecosystems recover from stress, ensuring long-term resilience.
How do human population levels affect sustainability?
More people means more resource use, increasing environmental impact.
What is the 'Tragedy of the Commons'?
Overexploitation of shared resources due to lack of individual ownership.
Why is ecosystem health important for sustainable management?
Maintains the balance of nature and provides essential resources.
How does resource consumption impact sustainability?
If consumption exceeds regeneration, resources are depleted.
How do greenhouse gas concentrations impact sustainability?
They trap heat, affecting the climate and environmental stability.
Why is food production important for sustainability?
Ensuring we can feed everyone without harming the environment.
What are the environmental consequences of overfishing?
Fish populations crash, potentially leading to extinction or strict regulations.
What is a consequence of increased greenhouse gas concentrations?
Trapped heat leads to climate change, affecting ecosystems and resource availability.
How does increased human population impact resource availability?
More people means more resource use, potentially leading to resource depletion.
How does deforestation affect carbon emissions?
Reduced carbon sequestration leads to increased carbon emissions, contributing to climate change.
What effect does habitat destruction have on biodiversity?
Habitat loss leads to decreased biodiversity, making ecosystems less resilient.
What is the effect of unsustainable agricultural practices on soil?
Soil degradation and erosion, reducing the land's ability to support food production.
