Natural Resources- The earths natural materials and processes that sustains living organisms Gas
Conservation- Sensible and careful use of the resources
Resources. Three main groups
iron, copper, aluminum
clay, sand, phosphates
Plants and animals
Environment- All factors that affect a living organism.
Ecology- Science dealing with the relationship between living organisms and the environment. Environmental Science- Science dealing with how the earth works, how humans interact with the environmental, and how environmental problems can be solved or managed. Stake Holders in Conservative Issues
Energy, nutrient cycling, and product design
Since the industrial revolution (mid to late 1800s) products have been designed for a “cradle to grave” life cycle Meaning the products are made then once something else comes along we throw it out. People choose to promote ecological effectiveness”- a “cradle to cradle” process Use it and then reuse it somehow instead of throwing it away. Eco-effectiveness
Create buildings, like trees, that produce more energy than it uses Make products that decomposes easily
Paper is a good one
Plastic is bad

Energy Source and Use
Other is the dung used in furences in some third world countries Renewable vs. Nonrenewable
9% of all resources use in the US
Non-renewable (will run out in the future)
91% of all resources used in the US.
Main fossil fuel driving the world and politics
Most wars have been fought over this resource.
Used for everything.
Largest source of environmental contamination.
Most refineries are located along the coast of the US.
Saudia Arabia has the most oil.
The middle east hold more than 60% of all oil.
Methane, propane, ethane, and butane
Larger reserves than oil
Produces less pollution than other fossil fuels
Easily transported by pipes but difficult to ship.
Russia and the Middle East have 66% of the reserves.
Lignite, bituminous (soft coal, the dirtiest), coal, anthracite (the oldest and “cleanest”) About half of the energy is produced this way.
Northeast area relies on it the most
Very abundant (10x more reserves than oil or gas) with high net energy but much of it is from low quality coal Very destructive environmentally and to human health.
