Economics have shown us the human development has shown
advancement, from trading commodities now we can even trade services such
as call centres. Technology has contribute a lot in human development. But with
all the development incurring the environment seem like having to take all the
negative side eect of the development. So KEB!" environmental economics
will try to analy#e what the ma$or causes of environmental problem happening in
the world. So to fully understand the problem we need understand the basic
principle of environmental problem which is pollution, to truly tackle this problem
at its root. %mong the environmental problem that can occur is pollution which
means contamination of harmful to&ic waste into the environment from factory,
vehicle and people own fault. % statement from the world wildlife 'ederation on
pollution(
)f we look at any ecosystem and there could be multiple forms of contamination
*streams full of to&ic chemicals from industrial processes, rivers overloaded with
nutrients from farms, trash blowing away from land+lls, city skies covered insmog. Even landscapes that appear pristine can e&perience the eects of
pollution sources located hundreds or thousands of miles away. ollution may
muddy landscapes, poison soils and waterways, or kill plants and animals.
-umans are also regularly harmed by pollution. ong/term e&posure to air
pollution, for e&le, can lead to chronic respiratory disease, lung cancer and
other diseases. To&ic chemicals that accumulate in top predators can make some
species unsafe to eat. 0ore than one billion people lack access to clean water
and !.1 billion don2t have ade3uate sanitation, putting them at risk of
contracting deadly diseases. %nd according to live science website article on
pollution facts and type of pollution4 there +ve type of pollution which is(
5. and pollution is because of household garbage and industrial waste. 'or
household most of the garbage would be from food. %nd according to the
6atural 7esources 8efence 9ouncil, up to 1:; of food produce in the
oating in the air.1. 6oise pollution is unable to be seen or smell but it still aects the
environment. 6oise pollution happens when the sound coming from
planes, industry or other sources reaches harmful levels. 7esearch has
shown direct links between noise and health, including stress/related
illnesses, high blood pressure, and speech interference and hearing loss.?. ight pollution is not well known because the side eect has not shown
critical or direct eect on environment but the eect could prove to be
fatal for some species like bird singing at unnatural hours because of

arti+cial light, Scientists have determined that long arti+cial days can
aect migration schedules, as they allow for longer feeding times.
So if we look at the facts above, it is important for us to understand the ma$or
causes of environmental problem among them are population growth, wasteful
and sustainable costs of resource use, poverty, e&clusion of environmental costsof resource use from the market prices of goods and services, and attempt to
manage nature with insu@cient knowledge.
opulation growth
opulation increase can have huge impact on the economy. %n increase in
the number of people to a country2s population means that the wealth must be
distributed among more people, causing A6 per capita to decrease at least in
the short term.
7apid population growth rates can make it di@cult for countries to raisestandards of living and protect the environment because the more people there
are, the greater the need for food, health care, education, houses, land, $obs, and
energy was 3uoted by the world bank webpage.
%s 3uoted from nova webpage )n !:5? the world population is more than .
billion people. That2s more than seven billion three hundred million bodies that
need to be fed, clothed, kept warm and ideally, nurtured and educated. 0ore
than . billion individuals who, while busy consuming resources, are also
producing vast 3uantities of waste, and our numbers continue to grow. The
owing and would end up getting
wash away into the river and would cause water pollution. 6ot $ust it causes
pollution to land but also air and water pollution.
=aste management is important e&pect if the number of population increases
because more waste is going to be dump. =hat is meant by waste management
is separating the waste from things that can be recyclable and thing that cannot
be recycled.
The e&panding of population must also meet the housing capacity in order to
avoid people crowding a certain place which can increase wastage capacity,
Dpening a housing area can also have a negative impact. 'irstly in order for you

to open a new land you must +rstly clear a part of the forest. 9utting trees will
aect the wildlife as they lose they habitat and end up e&tinct because of our
reckless action in planning a housing area. By cutting down the trees we also
allow ourselves to be in danger because without the tree we are e&pose to
danger like >ooding and even landslide. 6ot only tree provide o&ygen for us to
breath but they also can prevent landslide from happening because their root
grips a wide range of land thus providing grip to the land so landslide doesn2t
happen.
The aftermath of landslide problem can e&pand to >ooding. -ow can it e&pand to
become >ooding is when the land beside the river fell into the river because of
landslide the depth of the river decreases thus causing the water to over>ow and
causing >oods.
