main causes of global warming is to have a large amount of cacbon dioxide(CO2)
in the atmosphere. They contributed to increase in temperature in the planet.
People consume such fossil fuels as coal, oil, and natural gas for energy or
deforestation to have a place for
plantations and pastures. Besides, there are a lot of gases in Earth’s
atmosphere known as ” greenhouse gases”(GHGs) like methane(CH4),
nitrious oxide,…. They are pollutants making the problem become more serious.
In many poison gas existing in atmosphere, CO2 is one of the
greatest gas risks occuring in over many centuries. This gas will threaten not
only climate of future but also progeny later(Climatehotmap,
ten ho tac gia, nam). Human influence is also rapidly changing the climate.Scientists also
authorities drew a conclusion on global warming that the temperature of the
planet is increasing in at nearly twice the rate it was 50 years ago. Causes of
this epidemic are not only natural cycles but also effect of GHGs released by
people. IPCC- a groups specialized in researching and writing results about
newest scientific findings about our planet, they declared that people living
in the earth emitting toxic gas to environment in differents ways. It is ignition
of fossil fuels from vehicles, factories, industrialization, electricity
product. Landfills and agricultures also are impacted by methane ( especially
from the digestive systems of grazing animals), nitrous oxide from fertilizers,gas
used for refrigeration and industial processes,….However, each GHGs has a
diverse effect on environment. To name a few, a particle of methane generate
more than 20 times that of CO2. Nitrous oxide is 300 times more influential
than CO2. Other gas have a high ability of heat-trapping, but none
of these gas affect much warmth more than CO2 does. (Phan1, ho tac gia, nam)Another causes contributed to
increased emissions of GHGs is overpopulation. Nowadays, rapidly growing
population has become a huge menace to natural environment as well as human-being.
These responses have been made up many places for rice growing and cattle farming.
This makes methane go up dramatically and destroy our environment.(Pakenham,.n.d) Human influence has been a very serious issue now because
human do not take care about the earth. People cause global warming are more
than natural causes global warming. The earth has been changing for many years
until now it is still changing due to modern lifestyle of everyone. Human
activities include indutrial production, burning fossil fuel, mining, castle
rearing or deforestation made our planet become worse and worse.
