Top 4 Reasons Behind The Heating Of Our Earth


0

Global warming is affecting many parts of the world. Due to global warming, the glaciers are melting which are causing the rise in the sea level. When the level of the sea rises, it cause danger to the people living in the low lying areas. So, this cause a big problem for the people, plants and animals living on the earth.

When the level of the sea rises, it covers the plants and causes some of them to die. When they die, animals lose their main source of food. We, human beings lose our two sources of food, plants and animals. It may also force people to lose their homes. In other words, the whole chain will get affected if nothing is done on time to stop global warming from spreading its wings.

Here below are few of the main causes that are contributing their best towards global warming.

  1. Pollution:

pollution

Pollution whether it is vehicular, electrical or industrial is the main contributor to the global warming. Everyday billions of vehicles release various gases into the atmosphere. This causes earth to warm up and increase its average temperature. Electricity causes pollution in many ways.

Fossil fuels are burnt for e.g. Coal is burnt to produce electricity. Coal is the major fuel that is burnt in these power plants. Coal produces around 1.7 times as much carbon dioxide per unit of energy when flamed as does natural gas and 1.25 times as much as oil. Over 75% of the electricity worldwide is produced by burning fossil fuels. Many gases are sent into the air when fossil fuels are burnt of which main is the carbon dioxide gas.

Industries on the other hand release various gases into the water and air. Carbon dioxide, methane, nitrous oxide are the major greenhouse gases. Different gases have different heat trapping capabilities. Some of them trap more heat than carbon dioxide. Methane is much more effective then carbon dioxide in entrapping heat in the atmosphere. By driving cars, using electricity from coal fired plants and heating up our homes from natural gases, we release carbon dioxide and other heat trapping gases in the atmosphere.

  1. Deforestation:

deforestation

Deforestation is the cutting down of trees and plants to make way for any development activity. Carbon dioxide is the air that our body lets out when we breathe. Trees take in this carbon dioxide and release oxygen that we breathe in. With the cutting down of more and more trees is leading to greater concentration of carbon dioxide in the air.
This means that it is very important to protect our trees to stop the greenhouse effect, and also so we can breathe and live. Deforestation is blamed for rise in the greenhouse gases present in the atmosphere by cutting or burning them. New development projects, requirement of land for homes and factories, requirement for wood and also soil erosion are the major factors that are causing deforestation, which in turn leading to global warming.

3.   Landfills:

landfills

When we throw garbage out of our house it goes to landfills. Landfills are those big chunks of garbage that you must have seen on some expressway, when you go out of your city that stink. The garbage is then used by big recycling companies to make some useful products out from that garbage.

Most of the time that garbage is burnt which then release some toxic gases into the atmosphere. These enormous amount of toxic greenhouse gases when go into the atmosphere makes global warming worse.

  1. Population:

population

Another cause of global warming is population. Since Carbon dioxide contributes to global warming, the increase in population makes the problem worse because we breathe out carbon dioxide. More people means more demand for food, more carbon dioxide in the atmosphere, more demand for cars, more demand for homes and they all in somehow or other lead to global warming.

 

More demand for food will lead to more transportation since movement of goods and services is done by transportation sector. More demand for cars means more pollution in the air and more traffic on the roads which means longer waiting time on the traffic lights and will result more burning of fuel. More demand for homes means cutting down of trees to make way for homes, schools and colleges.
