All Flashcards
Define environmental sustainability.
Using resources wisely so future generations can also enjoy them.
What is sustainable yield?
The amount of a resource that can be harvested without reducing the base supply.
Define 'commons' in the context of environmental science.
Resources that are shared and not owned by anyone (e.g., oceans, atmosphere).
What is overexploitation?
Overuse of a resource, leading to depletion.
Define biological diversity.
A rich variety of life that helps ecosystems bounce back from stress.
How does sustainable yield contribute to environmental sustainability?
Ensures resource use doesn't compromise future availability.
How can reforestation help promote the sustainable use of a forest?
It ensures a continuous supply of timber while maintaining ecosystem health.
How can selective logging help promote the sustainable use of a forest?
It ensures a continuous supply of timber while maintaining ecosystem health.
How can the establishment of protected areas help promote the sustainable use of a forest?
It ensures a continuous supply of timber while maintaining ecosystem health.
What are the consequences of overfishing?
Fish population crashes, potential extinction, strict regulations.
How does increased consumption affect resource availability?
Puts more pressure on resources, potentially leading to depletion.
What are the environmental impacts of logging a forest at a rate that exceeds its sustainable yield?
Habitat loss, soil erosion, decreased biodiversity, increased carbon emissions, water pollution, or loss of ecosystem services.
