Since
human antiquity until today, humans have always been progressing in every
period of time passed. Current human civilization has been a lot of progress.
During development, the human living and being dependent on farming and agriculture.
Through the life orientation, people are always trying to maintain and preserve
the environment as well as possible which aims to sustain human life .
Humans
have now experienced the industrial revolution which lives depend on the
industry sector. By using the life orientation, world agriculture was declining
gradually. The values of human life underwent a change, especially in human interaction
with the environment. The changes that occurred this produces a positive or
negative impact
One
of the effects of the industrial revolution that has occurred and is continuing
on the present in the life and human civilization is its impact on the
environment that exists around the man himself. Expansion efforts by industry
players such as the construction of factories and manufacturing production with
a large capacity to the exclusion of attention to its impact on the environment
is slowly but surely have resulted in the negligence that will ultimately harm
the living environment and human life.
Environmental
experts have found indications of the impact on the environment and the world's
most globally due to efforts made and the industry has been growing rapidly at
this time. This negative impact is the warming in the world and is often
referred to as Global Warming. Global Warming on earth that every day more and
make the earth become worse.
However,
the problem of Global Warming as an environmental issue is still debated truth
by some parties who think Global Warming is a reason that was created to limit
the pace of industrial development. Although there is still a debate about the
truth of the state of global warming among environmental experts, the problem
of Global Warming is not able diungkiri to be researched and investigated
further for the survival of human life.
Global
Warming or Global Warming is the increase in the average temperature of the
atmosphere, ocean, and land Earth. Global average temperature at Earth's
surface has increased by 0.74 ° C ± 0:18 (1:33 ± 0:32 ° F) over the last
hundred years. Most of the increase in global average temperatures since the
mid-20th century, most likely caused by increased concentrations of greenhouse
gases due to human activity through the greenhouse effect.
Increasing
global temperature will cause changes such as rising sea levels, increased
intensity of extreme weather phenomena, as well as changes in the amount and
pattern of precipitation. Consequences of global warming include its impact on
agricultural output, loss of glaciers and the extinction of various animal
species.
Global
warming lately frequent cause tremendous impact on human life, Here I will
explain about some of the things that cause global warming and the impact of
global warming. Global warming, among others, due to the greenhouse effect, feedback
effect, deforestation. And actually there are many other causes that lead to
global warming.
Explanation
of global warming is happening because of the greenhouse effect. All energy
sources that exist on Earth comes from the sun. When this energy arrives the
Earth's surface, the light is turned into heat which warms the Earth. Earth's
surface will absorb some of the heat and reflect kembai rest. Some of this heat
tangible long-wave infrared radiation into space.
Some
of this heat tangible long-wave infrared radiation into space. However, some
heat remains trapped in the earth's atmosphere due to the accumulated amount of
greenhouse gases include water vapor, carbon dioxide, and methane that become
traps for this radiation. These gases absorb and reflect radiation emitted by
the Earth and consequently the heat stored in the Earth's surface. This
situation occurs continuously, resulting in an annual average temperature of
the earth continues to increase. These gases working in the greenhouse gas.
With the increasing concentration of these gases in the atmosphere, the more
heat is trapped below.
Explanation
of global warming is happening because of feedback effects that feedback
process that occurs affects the cause of global warming. An example is in the
process of evaporation of water. In the case of warming due to increasing
greenhouse gases like CO2, warming will initially cause greater volumes of
water that evaporates into the atmosphere. Because water vapor is itself a
greenhouse gas, warming will continue and increase the amount of water vapor in
the air until it reaches equilibrium with the water vapor concentration.
Explanation
of global warming is happening because of deforestation. Rampant cases of
deforestation is one of the causes of global warming today. Deforestation which
reduces the absorption of carbon by trees, causing the increase of carbon
emissions by 20%, and change the local micro-climate and hydrological cycle,
thus affecting soil fertility. Forests are the lungs of the Earth now can not
function optimally because it has a very reduced number of existing trees. The
number of trees there can not balance out the large number of existing CO2 in
the Earth.
Here
are some of the negative impacts of global warming is sea Circulation disturbed,
disturbing and have unknown effects on the world climate, desert becomes dry
and increased desertification, water shortages in areas already scarce water,
more extreme weather and increased frequency of storms and disasters,
Extinction animal and plant species, Increased air pollution.
The
positive impact of global warming the Arctic, Antarctica, Siberia, and other
frozen earth regions may experience more plant growth and temperate, less
energy consumption needs to warm up the cold, high mountains Improvement due to
melting glaciers, are higher because they rebound against weight lost of ice.
The
impact of global warming is not good for the development of good earth at this
particular time and in the future will come, therefore care about and love the
earth because the earth is our survival. The start to keep and preserve the
earth from now and reduce global warming for the good of our survival and his
successor to make the earth better.
