Acid Rain (pg 118) • Precipitation with a pH below 5.6 • May also be in the form of snow, sleet, or fog • Causes the deterioration of forests, lakes, statues, and buildings • http://video.kidzui.com/channels/acid-rain Back
Habitat Destruction (pg 118) • Damage to a habitat by air, water, and land pollution • Aka habitat degradation • Deforestation is also an example • http://environment.nationalgeographic.com/environment/habitats/?source=NavEnvHab Back
Non-native species (pg 120) • May take over niches of native species in an area and eventually replace them • Aka invasive or exotic species • http://www.sciencedaily.com/videos/plants_animals/invasive_species/ Back
Global warming (pg 128) • An increased amount of the greenhouse gas CO2 has prevented a large portion of heat from escaping through the Earth’s atmosphere • Effects: more frequent and severe heat waves, floods and droughts, glacial melting, rise of ocean levels, and intense storms • http://www.goldiesroom.org/Multimedia/Movie_Clips/22%20Ecology/Global%20Warming.wmv • http://environment.nationalgeographic.com/environment/global-warming/?source=NavEnvGlobal Back
Bioaccumulation • Gradual build-up over time of a chemical in a living organism • Similar to biomagnification, but within a single organism instead of over an entire food chain • http://science.jrank.org/pages/854/Bioaccumulation.html • http://www.nationalgeographic.com/search/?site=default_collection&client=default_frontend&proxystylesheet=default_frontend&output=xml_no_dtd&oe=utf-8&search=bioaccumulation Back
Deforestation • Clearing Earth's forests on a massive scale, often resulting in damage to the quality of the land • http://environment.nationalgeographic.com/environment/global-warming/deforestation-overview/ Back
Sustainable practices (pg 123) • Promotion of using natural resources in ways that will not, or will limit, damage the ecosystem over time • http://www.thegreenguide.com/?source=NavEnvGG Back
Stewardship • “The responsible use (including conservation) of natural resources in a way that takes full and balanced account of the interests of society, future generations, and other species, as well as of private needs, and accepts significant answerability to society” • Related to sustainable practices • Simply put: being a good citizen to the environment!
