7 Human Population and Environment part 5
Information and Electronic Revolution
With the beginning of the electronic age in recent years, Our world has become a place
where information and communication are regarded as the most valuable resources. Our
world has now shrunk to a ‘global village’ and we now have access to places our grandparents
didn’t know existed. Information from cosmopolitans to unexplored frontiers are all now
available at a drop of a hat, it’s just a matter of mouse-click. Data flows at the speed of light
in today’s wired world, or shall, we say the wireless, paperless and non-messy world. The
advent of the Internet has, in a way, brought continents together once again.
Modern technology has also minimized our utilization of resources; e.g. today’s,
sophisticated engineering has replaced the blind usage of metals in every production. Thanks
to the marvel of lightweight alloys and composite building materials, automobiles now
require half as much metal as they typically used to do a generation ago. Today 1,000 soft
drinks cans are manufactured with around 6 kg of aluminium, which once used to require
50 kg of steel. In the 1970’s, when the fear of an impending shortage of metals gripped the
world, countries like the United States began stockpiling essential minerals to keep their
resource inventory up-to-date. Copper for electric wiring, telephone cables, and electric
motors were in short supply. But then glass-fibre optic cables, ceramic magnets, microwave
relay systems and satellite communication networks were invented. We now have a copper
surplus.
Similarly, technology has also cut down our fuel consumption. Diesel engines replaced
coal-based steam engines in locomotives, which were, further replaced by more efficient and
pollution-free electric engines. The popularity of high-mileage yielding, fuel-efficient vehicles
have made the gasoline guzzling vehicles obsolete in the market. Such advancements in the
field of information technology have made distance between two places immaterial. Today,
people can communicate via teleconference and transmit data through fax machines and
computer networks, and save precious time & fuel wasted earlier in traveling for meetings
and business appointments. It is no longer necessary for all workers to commute to an office
building in the congested city to do their work. Increasingly, workers have home offices
linked electronically to co-workers, clients, libraries, databases, and business opportunities
elsewhere in the world. Commercial establishments are moving away from the brick-andmortar set-ups to more affordable, cost-efficient, far-reaching virtual offices on the Internet.
Suggestions
Almost every country in the world is spending more & more in the information technology.
Just-in-time delivery systems and recycling further reduce the amount of virgin materials
we use. We will probably never reach a point at which we don’t need to extract resources
from nature, but we may greatly lower our consumption rate as well as the rate at which
we produce wastes and pollution. This would surely have important environmental benefits.
QUESTIONS
1. What do you understand by the population growth and population explosion? Explains.
2. What is the relation between the environment and human health?
3. Write about the human rights and value education in 500 words.
4. How we can prevent the HIV/AIDS in the world?
5. What is the Role of information echnology in environment and human health and how it
helps the population?
