TECHNOLOGY AND THE EARTH'S SURFACE

Resources that exist in a fixed supply are nonrenewable (coal, oil, natural gas, iron, copper, aluminum). The use of these nonrenewable resources leaves waste in the forms of heat, polluting exhaust gases, toxic substances. Technology has impacted the earth's surface and its resources.


How do we get at these nonrenewable resources without damaging the earth's surface?


Consider for a moment the impact of: surface mining, construction and urban development, farming, dams, landfills, restoring wetlands, recycling, conservation efforts!


By now you probably recognize that there are limited amounts of global resources available to us and that you can have an effect on the total supply of resources by using those materials wisely.
