At that time what led to alternative fuels was a better way to make vehicles work better, but what truly led to the development of alternative fuels was to prevent global warming from happening. They are needed to produce less emissions and improve the world`s climate. If in the world the use of conventional fuels keeps growing eventually it could lead to global warming and hurt the planet and harm lives because those gases that conventional fuels release are not good to inhale. The question that is being asked by everyone is if alternative fuels serve their purpose and are they worth it. Some people might see alternative fuels important and some do not care, but they should because they serve their purpose in improving climate and producing fewer emission levels.
