INTRODUCTION
Environment is the
physical and biology immediate surroundings of man, man is part of the
environment and the environment is part of man. It is very difficult to separate
a man from his environment, he can only move from one to another. The
environment of man plays very important roles on mans health and his existence,
it means a conducive environment and man makes good country.
According
to RK JAIN and SUNIL S RAO, the two factors which contribute most vitally to
the economic progress of a country are the quality of its people and the
diversity and richness of its natural resources. JAIN and RAO still believe
that the quality of the people of a country depends upon these three factors
i.
The innate intelligence of the people
ii.
The cultural heritage
iii.
The physical environment in which they
live
Fertile land, minerals on natural vegetation,
fisheries and native animal life are the chief natural resources on which the
economic development of a country can be based. The variety and the richness of
natural resources of a country determine the patterns of occupation of its
people. The more diversified the natural resources of a country the more varied
will be their occupation. Different occupation offer varying egress of
opportunities than hunting. But the best opportunities for the shaping and
improving human ability and intellect are afforded by the occupation of
manufacturing by factor system, agricultural by modern method; modern means of
transport and communication and international trade and commerce, political administration
is also a good training ground for people intellect.
According
to JO OLUWANDE [1988] described water as another component of environment which
is increasingly scarce resources requiring careful economic and environment
management the situation is exacerbated in Nigeria by rapid population growth
and urbanization, its demand for irrigation in agriculture. At the same time
the engineering and environmental cost are much higher or new waste supplies
than for source already tapped, in Nigeria and other developing countries.
Water quality is poor and often unsafe for human consumption. In addition to
human suffering the economic and environmental damages from water pollution are
devastating.
Water
or river degradation is subjected to siltation from sediment loads due to soil
loss, itself linked to loss of forest and tree cover. They are also subjected
to significant net water with drawers slowing along their course, due to
agricultural, industrial, and municipal use as well as pollution from human and
animal waste, although the rivers posses significant natural capacity to assimilate and render harmless many pollutants the
existing inflows in most case substantially exceeds much natural capacities.
This fact together with other progressive education in stream flows ensure that
the river water quality in the vast majority of cases declines as one goes
downstream. The result include loss of livelihood for fisher flask, significant
impacts on human health from polluted water lords habitation for many birds
species and loss of land navigation potential apart from these, Nigeria rivers
are extricable linked with the history and religions believes of its people, and
the degradation of important river system accordingly offends their spiritual,
aesthetic and cultural sensibilities.
This
type of problem were also associated with other degraded areas such as soils
and vegetation, and natural pastures and including forest from very important
natural resources wild as well as domesticated animal life also depends upon
natural vegetation. The present standard of our forestry nationwide has sent
some of forest habitat into other band while some were eradicated. These
problems are giving the federal government of Nigeria the African union and
other global organization a great concern as they spends a lot to preserve,
maintain and improving the present situation.
1.1 BACKGROUND OF THE STUDY
Environmental
degradation is the deterioration of the environment through declaration of
resources as air, water and soil. The destination of ecosystem and extinction
of wildlife, it is defined as any change or disturbance to the environment
perceived to be dipterous or understandable.
As indicated by the I = DAT [Deregulation
Affluence Technology] equation, environmental impact [I], or degradation is
caused by the combination of an already very large and increasing human
population [P], continually increasing economic growth or per capital affluence
[A] and the application of resources depleting and polluting technology [T].
Environmental degradation is one of ten
threat officially cautioned by high level threat panel of the United Nations.
The United Nation international strategy for disaster reduction destines
environmental degradation as the reduction of the capacity of ‘the environment
to meet social and ecological objectives and need’
Environmental change and human health, a
special section of world resources 1998-1999 in this report described how
preventable illness and premature deaths are still occurring in very large
number. It vast improvement is made in human health. Millions of people will be
living longer health live than ever before. In these forest region of the world
an estimated 11 million children or a bound one in fire, will not live to see
their fifth birthday, primary because of environment related disease.
Child mortality is larger than combined
population of Norway and Switzerland, and mostly due to malaria, acute,
respiratory infection or diarrhea illness that are largely preventable.
1.2
CLIMATIC CHANGE AND PEMPERATURE
Climatic change affects the earth’s water supply
in a large numbers of ways. It is predicted that the mean global temperature
will rise in the coming years due to a number of atmospheric CO2 will rise, and
both of these will influence water resources, evaporation depends strongly on
temperature and moisture available to replenish ground water supplier.
Temperature from plants be affected by a rise
on atmospheric CO2, which can decrease their use of water from possible
increase of leaf area temperature increase can decrease the length of the snow
season in the winter and increase the intensity of snow melt in warmer seasons,
leading to peak runoff snow melt earlier in the seasons, affecting soil
moisture flood and drought risk and storage capacities depending on the area.
Warmer winter temperatures cause a decrease
in snowpack which can result in diminished water resources during summer. This
is especially important at mid latitude and mountain region that depend on
glacial runoff to replenish their river system and ground water suppliers,
making these areas increase in temperature will initially result in a rapid
rise in water melting from glacier and a decrease in the melt and consequently
the water supply every year as the size of the glacier get smatter and smatter.
Thermal expansion of water and increased
melting of oceanic glacier from an increase in temperature gives way to a rise
in sea level, which can affect the fresh water supply of coast al areas as well
as river mouths and delta with higher salinity refreshed further in land, and
intrusion of salt water result in an increase of salinity in reservoirs and
equators.
Seas – level rise may also consequently cause
by a depletion of ground water, as climatic changes can affect the hydraulic
cycle in a number of ways.
Uneven distribution of increase in
temperature and increase precipitation around the globe decrease in ground
water suggest a rise in sea-level even after melt water and thermal expansion
were accounted to fresh-water supply.
A rise in air temperature result in rise in
water temperature, which is also very significant in water degradation, as the
water would become more susceptible to bacteria growth.
An increase in water temperature can also
affected ecosystem greatly because of species sensitivity to temperature and
also by including change in the body of water self-purification system from
decreased amount of dissolved oxygen in water due to rises in temperature.

PROBLEM OF THE STUDY
Despite the laudable
environmental health program being implemented by various tiers of government
in conjunction with the global agent to make the people live in a healthy
conducive environment. The people of this state are still experiencing some
environmental health problems such as water pollution and air pollution as a
result of indiscriminate disposal of waste in the environment. This is coupled
with the concentration of federal environmental protection agency [FEPA] only
at the state capital, which does not allow other areas from feeling their
impacts in terms of monitoring and assessment.
1.4 PURPOSE OF THE STUDY
2. To
identify the causes of environmental degradation from the grass root
3. As
erosion to investigate the implication of environmental degradation on the
health of community.
4. To
see the factors that can reduce the vast environmental degradation in the
country
1.5 SIGNIFICANCE OF THE STUDY
The research work
still focus on the problems associated with environmental degradation; examine
the major implication on both economy and prevention of environmental
degradation in OYO STATE NIGERIA.
