2.5+Reduce+Destruction+of+Nature

//**Anticipated Length of Subunit**: 5 session of 50 minutes each //

//In this section students consider some examples of resource consumption that produce lasting damage. Are there sufficient resources to supply human food, energy, water and construction needs while still leaving sufficient resources to support the health of the ecosystems that provide many of those essential services? Examples of destruction and some of wise decisions of restraint and restoration of balanced conditions are included in this unit. Mountain top removal coal mining, and the use of excessive amounts of nitrogen leading to dead zones in the Gulf of Mexico are contrasted with the reduction in the size of the ozone hole during the last quarter century due to International agreements banning CFCs through the Montreal Accord. The subunit closes with an issue closer to home - choosing between a parking lot and a garden on campus. //

The ozone layer over the far northern hemisphere -- once relatively robust compared to the Antarctic concentrations -- would have developed a similar ozone hole by the 2020s if the Montreal Protocol had not limited ozone-depleting substances.
