  1. Chapter 11 Environment Lydia, Greyson, Exelman

  2. Chapter Overview • This chapter covers the many ways IT is used in relation to our environment, both positive and negative. The environment theme covers a wide range of topics. The increasing processing capability of mobile devices has enabled almost universal access to information, but the increased number of devices has impacted on health and the environment.

  3. Topic 1- Data Logging • Data logging systems use computers to automatically record data from sensors, without human intervention, over a long period of time. (Days, months, years) • Data logging has many applications; used by automatic weather stations that can record environmental data which can later be used for weather prediction; can monitor volcanic and seismic activity.

  4. Topic 2- Electronic Waste • E-Waste refers to old, broken, and obsolete computer and electronic equipment. • E-Waste includes monitors, keyboards, mice, printers, batteries, mobile phones, chargers, and other household electronic goods. • In 2007, over 2 million tonnes of E-Waste were thrown away in the US and less than 20% was recycled. • Unsafe Disposal- arsenic, lead, mercury, and cadmium. • Sources of E-Waste- originates on economically developed countries, Europe and North America. Cost up to 30 dollars per to recycle a computer equipment. Less developed countries are a dollar per computer.

  5. E-Waste Continued • Reduce: the amount of raw materials and energy used in the production of the product. • Reuse: or refurbish computer equipment, or donate it to those who could still make effective use of it, such as local schools, disadvantaged people in the local community or users in developing countries. This could also help reduce the digital divide. • Recycle: e-waste is another option, using specialist equipment to extract valuable materials including glass, gold, sliver, and platinum.

  6. Topic 3- Satellite communication • Advanced imaging satellites such as the GeoEye1 orbit team above earth and altitudes up to 680 kilometers, are capable of taking photographs of any location on the planet with incredibly high resolution. • Remote sensing: a setting other satellites use, like radio waves, lasers, or sound to gather data not visible using normal photography techniques. • Applications: weather monitoring, photos of the earth to monitor climate and environmental change.

  7. Topic 4- Mapping, virtual globes • Online maps often have data layers customized for their target audience, so a system for tourist use may include layers which display hotels, restaurants, car rental agencies and national parks. • Geotagged: images with location coordinates embedded • Virtual globes- software models of the Earth (or other planets) which provide similar functionality to mapping systems, but in three dimensions.

  8. Topic 4 continued • -Advantage: clearly showing the height of terrain features such as mountains, as well as allowing more detailed layers of information to be added. • Example: Software such as Google Street View takes the online mapping process even further by including images of entire streets in cities around the world. Users can move up and down streets almost as though they were present, viewing local buildings vehicles, and people.

  9. Beach Ball Question Game • Questions will appear on the PowerPoint and we will thrown the beach ball to a student to answer the question. • If you answer the question correctly, throw the ball to another person who wants to answer the next question. • If you answer the question incorrectly, throw the ball back to Lydia/Greyson/Exelman and they will throw it to another student.

  10. What is E-Waste? • E-Waste refers to old, broken, and obsolete computer and electronic equipment.

  14. What are Geotags? • images with location coordinates embedded

  15. What are the 3 Rs? • Reduce, reuse, recycle
