The benefits of the mobile phone
The mobile phone is a significant
technological advance in the field of communication. It allows anyone, wherever
they are, to be in touch with the rest of the world all the time.
On a global scale, the mobile phone
greatly facilitates communication especially in remote areas of the world
(where there is no traditional telephone infrastructure).
The prices of phones
are very affordable in most cases, they remain accessible to the middle class
and poor in almost all countries.

The disadvantages of the mobile phone
On a global scale, the 4 billion laptops
pose an environmental problem that one suspects only very little. Mobile phone
batteries contain pollutants that are very dangerous to nature and human health
(heavy metals). Specific systems are needed to collect these used batteries and
recycle them. In the less advanced countries, these systems are absent or
deficient. The batteries are then rejected in nature posing a certain
environmental problem.
Mobile phones also consume energy; on
average one hour of conversation is equivalent to the energy used by a washing
machine at 400C. CO2 emissions from the production of the world's 4 billion
mobile phones are estimated at 40 million tonnes, the equivalent of 20 million
cars.
