Our environment is more then just our surroundings
is the sum of our surroundings
It includes all of earths
Biotic Constituents = Animals, plants, soil, forests, people occupying
Abiotic Constituents = Continents, oceans, clouds, rivers, icecaps
In the most inclusive scene, our environment includes scientific, political, ethical, economical,
It is the interactions that characterize environment.
Most people equated environment with wilderness.

conserve our renewable resources and protect our water resources.
Environmental science explores interactions between humans and the physical and
We depend on the environment for air, water, food, shelter, and everything else essential
Some actions have enriched our lives, bringing us longer life spans, better health
Some have damaged natural systems that sustain us
is the study of how the natural world works, how our
environment affects us, and how we affect our environment.
It is important to understand our interactions and our role in the environment.
Natural resources are vital to our survival
Islands are finite and have limitation in material resources
Renewable Natural Resources
are natural resources that are relenishable over short
periods (wind, wave energy, sunlight.
Become non-renewable if we use them at a rate that is faster at which they are
renewed or replenished.

the use of a resource with its protection and preservation.

Non-Renewable Natural Resources
are finite supply & depletable as they are formed
much more slowly (fossil fuels, mineral deposits.)
Once we use them up they are no longer available.
Fossil fuels & minerals are mined rather than harvested, therore once extraction
becomes inefficient to be profitable they move on to new sites.
Management of non-renewable mineral resources demands conservation,
Other resources are
non-renewable and nonreplenishable (once a species has
become extinct it won’t return)
