Human Impact a. Coal burning plants release lots of (oxygen/carbon dioxide/sulfur dioxides) into the air. b. Which is NOT a greenhouse gas? (ammonia/ carbon dioxide/water vapor/methane). C. Deforestation causes (more/less) oxygen production due to an (increase/decrease) in photosynthesis. Trees that are cut down are often burned increasing (ash and particulate matter/sulfur dioxide) to be released into the air. d. The Sun's energy output is slightly (lower/higher) during periods with large numbers of sunspots. e. CFCS introduce (chlorine/nitrogen/sulfur) into the ozone layer. The ultraviolet radiation at this altitude breaks down CFCS which then break down (carbon dioxide/oxygen/ozone). f. Ground-level and airborne from burning are the two pollutants that pose the greatest threat to human health in this country.
