Primarily, Ganesh provides information about why global
warming occurs. Within the document,
“Global warming/greenhouse effect,” Ganesh states that when the “troposphere
[or] the lowermost layer of the atmosphere traps heat by a natural process due
to the presence of certain gases,” global warming occurs and the greenhouse
effect begins to take place (Ganesh 219).
Furthermore, the greenhouse effect occurs when “there is an increase in
the concentration of the greenhouse gases in the air which absorb infra-red
light containing heat, which results in the re-radiation of much of the
outgoing thermal infra-red energy, thereby increasing the average surface
temperature” (Ganesh 220). Although it
is important to understand why global warming occurs due to the greenhouse
effect, it is also important to note what causes this phenomenon. According to Ganesh, “the level of carbon
dioxide has increased due to human activities,” which in turn has also released
gases such as “methane, nitrous oxide and chlorofluorocarbons” (Ganesh 220). All of these greenhouse gases have helped to
increase the amount of heat captured by the troposphere, which in turn is
making the earth significantly hotter than in should be. In addition to the increase in gases,
“deforestation has further resulted in elevated levels of carbon dioxide due to
non-removal of carbon dioxide by plants through photosynthesis” (Ganesh 220). With the prevalence of the greenhouse effect
growing, global warming is definitely a severe problem that the world will face
in the near future.
Next, it is important to address the changes and
detrimental effects that global warming will cause to the environment as well
as the earth. Ganesh states that due to
the increase in the global temperature, “the hydrological cycle” will be upset,
“resulting in floods and droughts in different regions of the world, causing
the sea level rise, changes in agriculture productivity, famines and death of
humans as well as livestock” (Ganesh 219).
However, these are not the only detrimental changes that will be taking
place due to the increase in temperature.
Changes in the climate will increase the “warmth at poles,” as well as
“reduce the thermal gradient between the equator and high latitude regions,
which will “disturb the global pattern of winds and ocean currents as well as
the timing and distribution of rain fall,” (Ganesh 219). Ganesh goes into depth even further when he
claims that global warming will account for some dangerous problems in human
health as well. In “Global warming/green
house effect,” Ganesh claims that the number of deaths will rise due to
“diseases like diarrhea, cardiovascular diseases, etc.,” all due to the effect
that “fresh water availability will decrease by 2050” (Ganesh 220). There is an enormous list of effects that
global warming will have on the environment as well as humans, and the list
continues to grow.
Finally, by putting what causes global warming and the
effects that it produces together, it is important to teach measures to control
as well as reduce its harmful consequences.
Ganesh states that the “government should take severe steps to control
global warming,” and that “we should bring awareness among the people
(including rural people) about the effects of global warming” (Ganesh 222). By educating society about the seriousness of
global warming, individuals will be able to make decisions to help reduce its
major effects. Although this is one
measure that Ganesh proposes, a measure that is already in place is the use of
photosynthetic glass chambers. Photosynthetic
glass chambers “convert carbon dioxide into oxygen” (Ganesh 222). By replicating the process of photosynthesis,
one can now convert carbon dioxide into the much needed gas, oxygen. Furthermore, Ganesh states that other
measures to reduce global warming’s effects are to “cut down the current rate
of use of CFCs and fossil fuel,” “use energy more efficiently,” “shift to
renewable energy resources,” “increase nuclear power plants for electricity
production,” “shift from coal to gas,” “trap and use methane as a fuel,”
“reduce beef production,” “adopt sustainable agriculture,” “stabilize
population growth,” “efficiently remove carbon dioxide from smoke stacks,” “plant
more trees,” as well as “remove atmospheric carbon dioxide by utilizing
photosynthetic algae,” (Ganesh 221). By
making an effort or even switching up old habits, an individual can make a
small impact. As the awareness within
the population grows, measures to reduce global warming will be greatly felt.
In P. H. Roop Ganesh’s article, “Global warming/green
house effect,” one can easily see what factors that propel global warming, the
serious consequences that it will cause, as well as possible measures that help
limit its destructiveness. Although not
everyone in the entire population of the world cares about global warming, it
is still important to educate individuals so that they can help make a
beneficial impact. The earth is ours and
we constantly take it for granted. It is
time to make a change and it is time to save the beautiful world that is
inhabited by all of us.
