1. GARBAGE ACCUMULATION
Garbage in a city can cause a variety of problems. These include
contamination of ground water, surface water, and even the cities
water system, if leaching of chemicals occurs from the disposal site.
A lowering of pH by these chemicals can add to acidity problems in
the
water and even the air. Landfills can also cause sealing of the
ground surface, which will lead to flooding.
Disposal areas attract wildlife, such as rats, dogs and birds.
Besides causing a danger of wildlife/ human interactions (birds flying
into planes, or dogs in roaming in packs) these usually bring diseases
with them, such as plague, meningitis, pneumonitis, and
toxoplama-gondii.
Another problem is the accumulation of infectious or toxic waste
items. May people in cities do no destroy dangerous items, they often
just throw objects that should be incinerated. This can create a heap
of items as dangerous as medical waste or toxic and corrosive
chemicals. Often there are infectious diseases associated with
2. medical waste that can cause or heighten an epidemic.
In short, garbage pollution in a city causes a myriad of problems.
These include but are not limited to contamination of air & water,
increased disease risk, attraction of undesirable wildlife, soil sealing
and flood problems.
Garbage accumulation in cities has been a problem all over the world
for centuries. Garbage is created both at a government level and at
the level of individual households. Landfills have always been
regarded as sources of disease and offensive odors. Early in their
development cities generally have few disposal regulations and
individual homes disposed of garbage in their own unique ways.
Therefore, means of disposal were based on the culture, background,
occupation and size of each of the different households (Crane,
2000). Throwing away garbage is always a balance between hygiene
and thrift (Lucas, 2002). Used material may come in handy at a future
date, but in the mean time, storage of it causes certain problems, not
the least of which is sanitation concerns.
WATER POLLUTION:
Rain water percolates through garbage. The runoff from the rain will
then become contaminated by the sewage, sediment, chemicals and
diseases that are contained by that garbage. It is therefore necessary
for garbage dumps to either be waterproof or clear of water born
contaminants. Or, a better solution is to have garbage disposal not
present in the water shed of the public drinking supply. This is more a
concern in many developing countries than in countries that are more
economically advanced. Socio-economic factors make it very difficult
to solve these types of urban drainage problems (Silveira, 2002)
AIR POLLUTION:
3. Air pollution is the introduction of chemicals, particulate matter, or
biological materials that cause harm or discomfort to humans or other
living organisms, or damages the natural environment into the
atmosphere.The atmosphere is a complex dynamic natural gaseous
system that is essential to support life on planet Earth. Stratospheric
ozone depletion due to air pollution has long been recognized as a
threat to human health as well as to the Earth's ecosystems.Indoor air
pollution and urban air quality are listed as two of the world's worst
pollution problems in the 2008 Blacksmith Institute World's Worst
Polluted Places report.[1]
SOIL POLLUTION:
Soil contamination (soil pollution) is caused by the presence of
xenobiotic (human-made) chemicals or other alteration in the natural
soil environment. This type of contamination typically arises from the
rupture of underground storage tanks, application of pesticides,
percolation of contaminated surface water to subsurface strata, oil
and fuel dumping, leaching of wastes from landfills or direct discharge
of industrial wastes to the soil. The most common chemicals involved
are petroleum hydrocarbons, solvents, pesticides, lead and other
heavy metals. This occurrence of this phenomenon is correlated with
the degree of industrialization and intensities of chemical usage.
SOLUTION:
Rather than control garbage disposal through negative legislation,
there are many people attempting to come up with positive solutions
to this problem. Cohen, promotes a plan, in New York City, which is
sponsored cooperatively by the city and the state, to build high-
temperature incinerators that generate electricity. This way, the
garbage no longer is a disposal problem, it is instead an energy
source (Putting Garbage to Good Use).

dustbin!
CONCLUSION:
Garbage pollution is a serious problem in urban areas. Disposal has
been a concern of urban governments since the first city. It can cause
a myriad of problems for the citizens and wildlife in the urban area.
These range from creating an unpleasant atmosphere to creating a
center for disease infection, to altering the environmental quality of
the water, soil and native population.
