Fossil Fuels Journal Entry
Human consumption of fossil fuels is getting bad. We are using so much of fossil fuels to power our daily lives, that eventually we will run out. It is also effecting and polluting our earth and atmosphere. We need to find a safer alternative for these fossil fuels. Something that wouldn't pollute our atmosphere and we wouldn't run out of. The pollution from these fossil fuels is causing Global Warming which is causing a lot of other problems. We use fossil fuels for so many things. For example: gas, oil, electricity, ect. Since we use those things for almost everything of our daily lives, it's impacting the earth at an alarming rate. Pretty soon, there will be no fossil fuels left. What would we do then if we don't find an alternative energy source by then? In some countries, they use sugar cane or corn to power their vehicles. We don't have enough of those resources in America to power everything with sugar cane or corn, but I'm sure we'll find something eventually.

Coal
Coal is mostly made of carbon and hydrocarbons. It is a nonrenewable because it takes millions of years to be created. For millions of years, layers of dead plants on the bottom or the swamps was covered in water and dirt. That is what trapped the energy of the dead plants. The pressure and heat from the top layer helped form coal.
