This presentation discusses the positive and negative environmental impacts of information technology. It begins by defining information technology as the acquisition, processing, storage, and dissemination of information using microelectronics and telecommunications. Some benefits mentioned are reduced paper and ink consumption, as well as ability to monitor environmental changes. However, manufacturing computers uses chemicals and fossil fuels and their disposal pollutes the soil and water. Old electronics contain toxic materials like lead and mercury. The presentation recommends that industries reduce toxic substances and that governments set up e-waste recycling programs to properly dispose of old electronics. It encourages reusing or recycling old electronics to reduce their environmental effects.

Monitoring and controlling changes in
the Earth’s environment

6. Information age or computer age
Information technology
Telecommunications
77% of world population owns
mobilephones
4-5% of world population owns PCs!

8.  Every single computer requires
about 1.8 tons of chemicals,
fossil fuels and water for its
manufacture.
 Emission of about 0.1 tons of carbon
dioxide in a year.
 Dumping of old computers in land fills
Soil pollution.

10.  The CRTs which contain significant
amounts of lead.
 LCDs are illuminated by
mercury-filled panels.
 Circuitry contain chromium, copper, and
lead that exceed regulatory limits.

11. Effects Of Mobile Radiation
on:
 Farm animals
 Birds
 Honey bees

12.  INSTITUTIONS/INDUSTRIES FOR WASTE
DISPOSAL
 GOVT. INITIATIVE
 INDIVIDUAL COMMITMENT

13.  TheIT related industries (esp. the
manufacturing ones) should reduce the
use of toxic substances in products.
Recycl i ng pl ant s and col l ect i on
cent er s shoul d be set up.

14. The GOI has passed
strict rules in 2010 for
e-waste management
and disposal.
Has taken a strong
stand in international
forum.
 More initiatives are
expected from GOI

15. what should
we do ??

16.  Option1:
If your computers are in working
condition, you can donate them to a
school or an organization working in the
field of education.
 Option2:
If your computers are out of order,
return them back to the manufacturer.
 Option3:
Send them to a recycling facility for
proper disposal.

17. Do you really need
one?
Think twice,
be wise!!
