HR Test One Study Guide
(1) What do you need to have a sustainable society?
Environmental Sustainability = Economic Sustainability
What is sustainable development?
one that meets the current and future basic resource
needs of its people in a just and equitable manner without compromising the
ability of future generations to meet their basic needs.
live without degrading the
environment or disregarding future generations.
(2) What is natural capital/natural resources?
Be able to list them!
— the natural resources and natural services that keep us and other forms of life
alive and support our economies.
are materials and energy in nature that are essential or useful to
humans. These resources are often classified as renewable ( such as air, water,
soil, life, plants, and wind) or nonrenewable ( such as copper, oil, and coal, fossil
fuels, nuclear power)
What are natural services? - be able to name them
Air purification, Water purification, Soil renewal, Nutrient recycling , Food production, Pollination
Grassland renewal, Forest renewal, Waste treatment, Climate Control, Population control,
(species interactions) and Pest control
What is an ecosystem?
communities of plants, animals, and microbes along with the a biotic components such as soil
What is the link between biodiversity and natural services
? Certain species provide ecosystem services
Examples are species that protect soil from erosion (grass), influencing the characteristics of the
atmosphere (trees), transform energy from the sun into food energy (plants), and modify the ecosystem
to allow other species to exist (elephants)
What perpetual vs. nonrenewable vs. renewable resources?
Can you differentiate between them?
will never be used up.
The energy of the sun is the only example.
Energy from the
sun is used by plants (biomass, food), makes the wind blow (wind power and climate), and
evaporates water ( hydropower and climate control).
can be renewed on a time scale comparable to our lifespan – typically in 0-100
Trees are a good example of a renewable resource. While biodiversity is renewable,
very often the time scale is on the order of 1000s of years!!
This does imply that new species
can be created in that time period (that may take millions of years
cannot be renewed in our lifetime.
Examples are mineral resources and our typical
energy sources: coal and oil.
The earth processes that have created these resources are still
operating, but on a very slow scale.
What is the tragedy of the commons
where a resource is not protected and is degraded through
– it applies to both
