Water
Mexico city is built on an underground a guider
which significantly depleted. In general much of the water in the basin
is heavily polluted, acquitters and over that supply its water are over
extended and polluted; cholera recently have killed many people.
Today
most of the food and water consumed writhen the basin comes from
outside its boundaries may parts of the city suffer from water shortage
and industrial use of water is very inefficient water receding uses only
7% of the savage, and nearly 20% of the water supply is lost through
deficient pipe system. Pipe breakage represents a countries health
hazard, as microorganisms from the sewage system can contaminate the
fractured pipes.
Waste
Approximately 4-5 m3.5 of sewage water are
treated and used mainly for irrigation in parks and public spaces. The
remainder is eliminated from the basin by means of the deep drainage
system that was built in the early 1970s and by the old surface drainage
canals. This waste is mostly used for irrigation, constituting an
important source of agricultural pollution.
The health and
environmental effects of inadequate solid waste disposal are felt for
beyond the city in the form of water, land and air contamination on a
wide area. The city produces appropriately 10,000 loans of domestic
garbage per day. In consrate to developed countries, which generate
liter wish a low proportion of organic residues, the garbage of Mexico
city is rich in vegetable and fruit waste, and consequently could be
used for making compost at a relatively low cost. Until 1987 most the
residues were dispraised of in open field, recently a mix modern systems
of sanitary filling into dredged pits has become operational.
Extending
and huproving waste collection, processing and disposal services is
vital to control mounting health problems and prevent further damage to
the environment.
Air
City streets citoged with traffic and air
pollution is perhaps the worse protean the city faces. Photochemical
smog is critical during the winter months when a temperature mersion
stabilizes the atmosphere above the basin and the air pollutants
accumulate in the stationary layer of air that covers and factories.
Most
of the air pollution originates from automobile exhaust, which are
responsible for 72% of all atmospheric pollutants in mexicocity mean
ozone levels in Mexico city are ten time the normal atmospheric
concentration and are more than twice the Mexico limite allowned in the
united states. In order to alleviate this problem, the vehicles of
Mexico city are under a permanent vehicles program called “Hogno
circuld†all vehicles according to the last digit of their license plate
are distributed by colours along the week, and are not allowed to be
driven once in a week.
Air quality report are published daily through
the national media. Based on this reports vehicle use and industrial
activity are restricted, in order to protect Mexican people’s health.

ABSRACT - [ Total Page(s): 1 ]The work is motivated by the seeming inability of the public sector to make and implement polices and programmes to curb the high rate of rural – urban migration and unemployment that is usually experienced in Nigeria. The study was geared towards an overview of the issues of urbanization and unemployment as well as their implication on the development of Nigeria. Secondary data were collected and analyzed using ordinary least square method. The result obtained from the analysis shows tha ... Continue reading---
