Topic• Information technology (IT) is the acquisition, processing, storage and dissemination of vocal, pictorial, textual and numerical information by a microelectronics-based combination of computing and telecommunications.• Having both positive and negative effects on environment.• What can be done to maximize POSITIVE aspects and minimize the NEGATIVES?
+ aspects of IT 1) Reduction in consumption of paper: i) Use of digital database ii) Uses of e-books iii) Less letters more calls, SMSs and e-mails iv) Less greeting cards more online and text wishes 2) Reduction of use of writing and printing inks 3)Reduction in transportation: i)data transfer through e-mails, FAX, telephones and cell phones ii)shopping through e-marts iii) banking through e-banking and ATMs. iv) use of TELEMEDICINE.
+ aspects of IT 4) compact space, reduction in cutting of trees 5) Monitering and controlling changes in the Earth’s environment through satellites 6) Spreading awareness regarding environment through INFORMATION TECHNOLOGY: using television, internet, radio channels and messages.
21st century• Information age or computer age• Information technology• Telecommunications• 77% of world population owns mobile phones• 4-5 % of world population owns PCs
Computers • Every single computer requires about 1.8 tonnes of chemicals, fossil fuels and water for its manufacture. • Emission of about 0.1 tonne of carbon dioxide in a year. • 2 per cent of worlds total carbon dioxide emissions • Global warming • Dumping of old computers in landfills • Soil pollution
E- Waste from IT>>Discarded electronic or electrical devices or their partsSuch as Discarded Computers Televisions Monitors Laptops Cell Phones VCRs Stereos Copiers Fax machines
Dangerous elements in E-waste from IT The cathode ray tubes (CRTs), which contain significant amounts of lead. Liquid Crystal Displays (LCDs) are illuminated by mercury-filled panels. Circuitry contain chromium, copper, and lead that exceed regulatory limits. The batteries contain such as lead, nickel, cadmium, silver, lithium, and other dangerous metals.
Mobile radiation:Effects on environment Farm animals - Dairy cows – •Decreased milk production •spontaneous abortions • reproductive problems •general declines in overall health. •Sheep, dogs, cats, rabbits living near base stations affected.
Mobile radiation:Effects on environment Birds – • Interfere with navigation, reproduction, thin shells. • London - 75% fall sparrow population. • Fall in Pigeons, swans, white stork, rock dove •Biological indicators to detect alterations in our ecosystem
Mobile radiation: Effectson environment Honey bees Colony Collapse Disorder (CCD): • Abrupt disappearance of bees. • Cannot find their way back to hive due disruption in intercellular communication. CCD has hit – US (up to 70 %), England (54% fall), Germany, Spain, Italy, Switzerland, Greece, Scotland, Wales, Kerala etc
MANAGEMENT & CONTROL • INSTITUTIONS / INDUSTRIES FOR WASTE DISPOSAL • GOVT. INITIATIVE • INDIVIDUAL COMMITMENT
INSTITUTIONS & INDUSTRIES Role: • The IT related industries (esp. the manufacturing ones) should reduce the use of toxic substances in products. • Recycling plants and collection centers should be set up . Do not DESIGN TO Dump ! Instead, DESIGN TO LAST !!!
Government initiative• The GOI has passed strict rules in 2010 for e-wastemanagement and disposal• Has taken a strong stand in international forum.• More initiatives are expected from GOI.
