plants and animals. Currently supply 80% of worlds energy
The Anthropocene - the modern geological era during which humans have
dramatically affected the environment via human energy consumption
Greenhouse effect - Natural situation in which heat is retained in Earth's
atmosphere by carbon dioxide, methane, water vapor, and other gases
Hydrologic cycle - The cycle through which water in the hydrosphere moves;
includes such processes as evaporation, precipitation, and surface and
groundwater runoff
, Impact of Increased carbon dioxide - results from the burning of fossil fuels and
acceleration of hydrologic cycle leading to infrequent natural disasters

to climate change
IPCC - Intergovernmental Panel on Climate Change, panel of scientists and
researchers has been one of the main bodies in environmental control and

Ocean acidification - when CÓ dissolves in seawater, it reacts with water to form
carbonic acid, which lowers ocean pH
Particulate matter - a small discrete mass of solid or liquid matter that remains
individually dispersed in gas or liquid emissions (usually considered to be an
atmospheric pollutant)
Nutrient enrichment - nutrients are removed from one area and added to another
can lead to excess in nutrients facilitating growth of plants and algae
