Global
Warming is got by so many affairs. The causes are separated into two
groups, man made or anthropogenic causes, and natural cause.
Raw
causes are causes created naturally. One raw cause is a liberation of
methane gas from arctic tundra and wetlands. Methane is a greenhouse
gas. A greenhouse gas is a gas that snares heat in the earth's
atmosphere. Another natural cause is that the earth goes through a
planned climate change. This climate change usually lasts about
40,000 years.xEOL.xBL.Man-made causes believably do the most
impairment. There are many man made causes. Pollution is one of the
biggest man made problems. Pollution comes in many shapes and sizes.
Burning fossil fuels is one thing that has pollution. Fossil fuels
are fuels got of organic matter such as coal, or oil. When fossil
fuels are burned they give off a green house gas called CO2. Also
mining coal and oil allows methane to escape. How does it escape?
Methane is naturally in the ground. When coal or oil is mined you
have to dig up the earth a little. When you dig up the fossil fuels
you hunt down the methane too.
And
a second major man made cause of Global Warming is population. More
human race means to a greater extent food, and more methods of
transportation system, right? That implies more methane because there
will be more burning of fossil fuels, and more agriculture. Now your
belike thinking, "Wait a bit, you said agriculture is going to
be damaged by Global Warming, but now you 're saying agriculture is
going to help cause Global Warming?" Well, have you ever been in
a barn full of animals and you smell something awful? You 're
smelling methane. Another source of methane is manure. Because more
food is needed we have to raise food. Animals like cows are a source
of food therefore more manure and methane. Another problem with the
increasing population is transportation system. More peoples means
more cars, and more cars means more pollution. Also, many citizenries
have more than one car.
