Environmental Science Chapter 1 September 3 2015 Brooke Yaffa Environmental Science A field of science that is used to understand the natural world and our relationship to it Empirical Science Applied Science Approach that investigates natural world Research whose findings are used Through systematic observation and to help solve practical problems Experimentation Ecosystems are naturally sustainable This means that without any disruptions an ecosystem can support a certain population In the world we see a major loss of Biodiversity This means that there is a decrease in the natural services that world provides for us Ex Bees pollinating owers for us Earth is unique and humans have a large impact on the environment There are many environmental problems that are not easy to solve such as I Food shortages I Water shortages I Diminishing Fossil fuels I Climate change I Air pollution I Water pollution I Health problems Vocabulary Words Carrying Capacity Population size that and area can support indefinitely Ecological Footprint Land needed to provide resources and assimilate waste of a population Ex What food we eat the amount of land needed to grow crops or raise cattle and so on Nonrenewable resources Resources in finite supply or not replenished quickly enough to continue to support the ecosystem and population Renewable resources Resources that come from an infinitely available or easily replenished source Sustainable Using resources in a way that a population can use them indefinitely Making sure that generation that follow can also survive in the same manner Environment The surroundings and conditions in which an organism exists Environmental literacy The basic understanding of how ecosystems function and the impact of our choices on the environment Tradeoffs Imperfect and problematic responses that we must at times choose between in regards to complex problems Social Traps Discounting the future is a term that refers to the idea that shortterm benefits outweigh longterm benefits Tragedy of the Commons Talks about using as much land as fast as possible due to competition The thought process behind it is If I don t use it someone else willquot This ultimately degrades the land until it can no longer be used for the intended purpose Time Delay This social trap is seen over time If a person uses too much of a resource before it has time to replenish then we see a total decrease in that resource Ex Overfishing in an area to a point where the ecosystem is destroyed Sliding Reinforcer Commonly seen when addressing a certain problem first and then noticing that the certain problem has become immune or another problem occurs Then the target changes and the problem or solution is constantly changing along with it Ex Certain animals were targeted with pesticides soon one animal became immune so to solve that problem different pesticides were used to try to eliminate the problem The ecosystem is damaged in the process World Views Biocentrism This ideology is human centered Life centered ideology Humans and other Only humans have intrinsic value species have rights to exist and be Utility protected Due to life System centered ideology Value is given to ecosystem as a whole A biotic amp biotic Environmental Science Research and Data that attempts to solve a problem VS Environmentalism Social movement that promotes solving a problem
