Fossil fuels are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms, containing organic molecules originating in ancient photosynthesis that release energy in combustion. Such organisms and their resulting fossil fuels typically have an age of millions of years, and sometimes more than 650 million years. Fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas. Commonly used derivatives of fossil fuels include kerosene and propane.
- This generation has altered the composition of the atmosphere on a global scale through radioactive materials and a steady increase in carbon dioxide from the burning of fossil fuels.

- At issue is not whether the global economy will pass away. It is passing away. Rising populations and debt combined with depletion of freshwater sources and fossil fuel make the status quo untenable. The only question is whether civil society will survive the transition.
- We have a moral responsibility to help working families in the fossil fuel industry find new jobs.
