Question: Why are fossil fuels cheap, in limited supply, and dirty? Each answer needs to be at least 1 paragraph (5-10 sentences)
Answer:
1. Why are fossil fuels cheap?
Fossil fuels release bad things when they are burnt. For example, when you burn fossil fuel, it might release carbon dioxide (CO2), just like coal does when they are burnt.Carbon dioxide is a gas that we breathe out and the plants breathe in. The oxygen and carbon dioxide was balanced long time ago because there were many plants by then, however, people care cutting down the trees and plants so there aren't much plants that could keep up the process. Nowadays carbon dioxide is the main reason that is destroying the ozone layer in our atmosphere and is causing the global warming. So regardless of how much fossil fuels may help us, all the countries in the world doesn't want to use fossil fuels so the fossil fuels are cheap.
2. Why are fossil fuels in limited supply?
Fossil fuels are in limited supplies these days. This is because fossil fuels are non-renewable. This means once fossil fuels are burnt up, they won't be used again. They will just become a pile of ashes and just release carbon dioxide. They have to take a long process of million years in order to become an oil (fossil fuel) or a coal.
3. Why are fossil fuels dirty?
Fossil fuels are dirty. This is because many things (such as chemical, etc.) are combined inside. Fossil fuels, just like human, releases dirty gas while they are decomposing and being made as a fossil fuel. When people dig up the fossil fuel, it is impossible to dig it without digging the dirty fossil fuel gas too. Another reason that people say fossil fuels are dirty is because just as I mentioned above, it releases gases that harm humans and are dirty.
