Now, to the important facts: There is only one species of cannabis. The Herald-Whig article correctly stated that cannabis sativa is the only species of cannabis. However, the article implies a botanical difference between marijuana and hemp. There is no difference.
Today, fossil fuel industries drill or mine for these energy sources, burn them to produce electricity, or refine them for use as fuel for heating or transportation. Over the past 20 years, nearly three-fourths of human-caused emissions came from the burning of fossil fuels. The Energy Department maintains emergency petroleum reserves, ensures responsible development of Americaâs oil and gas resources and executes natural gas regulatory responsibilities.
Over millions of years these remains become the carbon-rich coal, oil and gas we can use as fuel. When fossil fuels are burned they release carbon dioxide into the atmosphere which contributes to global warming. Using fossil fuels to generate energy also releases pollutants into the atmosphere-such as sulphur dioxide.
