Every country, nation, or city in this world uses electricity, but how do we get this electricity? Some of us get it from water this is known as hydro electricity, others from the sun or solar electricity, or even a fossil fuel called coal. At this time in our world coal is the main source of electricity. Coal is harmful to our environment and to humans. but currently we do not have an efficient enough substitute source to just eliminate coal totally.

Coal causes many different types of problems in our world one of the most important and dangerous is the damage that coal does to our environment. The Union of Concerned Scientist says that the average coal plant puts off 3.7 million tons of carbon dioxide which is equal to cutting down 161 million trees; this is damaging because they believe that this carbon dioxide causes 50 % of Global Warming. The factories that clean the coal use water from lakes and rivers to clean it this process takes away from the fish that live in the water and animals that drink that water because then there is not enough for them to drink or live in once this happens. There becomes competition in that environment so animals die off because they do not have enough resources to stay alive. When this water is no longer needed to clean the coal the factories store it in old coal mines the problem with this is that if or when the mine springs a leak the polluted water is then mixed with the unpolluted water , and then the water is dangerous to humans and animals in that environment. After the coal is clean it is sometimes stored outside. When it rains the water runs off the coal and transfers metals like lead and arsenic back into the lakes and rivers in the area, and theses metals can also kill off the a...

...he wind doesn't blow every day and in some place it does not even blow every week. Coal is what most of the world uses at this time a 500 Megawatt coal power plant can produce as much of half a million kilowatts of electricity in one year.

Coal is the most practical object to use for energy at this time, but it does have many dangerous effects on humans and the environment. If people do not make some kind of change in the future then Earth will come to an end sooner than what people want it to. The coal pollution will eventually destroy what is left of our world or in the near future humans may not be able to reproduce because of the PAH particles that are caused by coal combustion and the human race will come to an end. Fortunately the process to slow this down is very simply we just need to cut down on coal and use other sources in places that it is available
