Who Needs Geology?
Supplying the things we needEnergyPlasticsMetalsMaterials for basic necessities of life (homes, appliances, cars, etc)

We all need clean water for our survival. Clean water does not come free.
Who Needs Geology?
Protecting the environmentThere is a cost for using the EarthCarbon emissionsGreenhouse effectErosionIce caps and glaciersOverpopulation
Our energy demands come with a high price: pollution.
Intense pollution may contribute to the greenhouse effect
Glaciers are responsible for shaping the earth for millions of years. The world’s supply of glaciers are melting rapidly.
We must figure out ways to provide the necessary materials for a rapidly growing population.
