Transcript of Sustainability
Natural Resources play an important role in the development and sustainability of a community.
meeting the needs of the present without compromising the ability of future generations to meet their own needs
occurs when a resource is used beyond its rate of replacement
Factors Affecting Sustainability
number of people
amount of resource
availability of resources - ex. lack of water = drought
rate of use
quality of resource - industrial accidents (exs: nuclear, oil spills)
natural disasters - EQ's, tsunamis, volcanic eruptions,
how do we produce enough food to meet our needs?
World Energy Usage
How do the natural resources of a community affect its sustainability?
How do communities manage and distribute natural resources in order to seek sustainability?
How might alternative energy resources minimize the negative impacts of nonrenewable energy resources?
new resources identified (exs: renewable energy, new fertilizers)
advancements in technology (plow, tractor)
management of resources (also being mindful of carrying capacity)
Carrying Capacity = the maximum number of a species an environment can support in a sustainable fashion based on resource availability.
