  9. Env. Issues –Greenhouse Effect & Global Warming • Greenhouse effect = • process by which water vapor & gases in the atmosphere absorb & reflect infrared rays & warm Earth’s surfaces • Global warming = • an increase in earth’s temperature

  10. Env. Issues – Destruction of the Ozone Layer • Ozone = form of O2 • Ozone layer = protective layer of the upper atmosphere that traps ultraviolet (UV) radiation from the sun and prevents it from reaching earth’s surface • CFCs = chlorofluorocarbons – group of gases that are easy to compress & expand / used as a propellant in aerosol sprays & coolants

  11. Env. Issues – Destruction of the Rain Forests • Rain forest = • hot, wet, forested area that contains many species of trees, plants, & animals – 7% of earth’s land • Source of food, rubber, timber, ingredients for prescription drugs • Forests are being cleared for agriculture – trees produce O2 & absorb CO2 and it can kill many species of plants & animals
