Global warming is one of the main issues being discussed in the world it is discussed by politicians, the media and even individuals. What we really do not know is the main cause of global warming, whatever the causes we come up with are merely the once the human can see and detect but there may be other natural factors that cause global warming. The fact remains that it has so much effects on animals, agriculture and its effects to human beings are scarier. As it has been researched the main causes are from human beings and so the effects will still harm us the most.

Emission of carbon dioxide burning fossil fuel plants
With electricity being the main source of energy its production is in massive and hence as the coal is being  burnt a lot of carbon dioxide is realized into the air ,and since more electric gadgets are being manufactured  we need electricity and since we do not have any other source of electricity we will go on burning coal.

Emission of carbon dioxide from burning gasoline for transportation
As the population increases the demand for more cars increases and this means we continue using fossil fuel which when burnt produce a lot of carbon dioxide in the air. If only we could come up with cars that used water instead of petrol.

Emissions of Methane from animals and agriculture
The methane is mostly produced when organic matter is broken down under conditions that are oxygen starved. This is mostly seen in green houses. Methane is also produced in the digestion of livestock animals so with the increase of livestock animals there is an increase of methane in the air which is another cause of global warming.

We all know that trees remove and store carbon dioxide from the air, this way global warming is reduced. But because of our greed for paper and charcoal and wood and also land, deforestation has tremendously increased leaving the land bear and hence an increase in carbon dioxide in the air which causes global warming.

The use of chemical fertilizer on cropland
We all stopped using manure from our animals on our soil to make it fertile. Everyone has resolved to use chemical fertilizers which in the long run, have effects that can cause global warming. Also not that high nitrates, found in the chemical fertilizers, in ground water due to over fertilization are causes for concern for human health.
