Not to long ago we thought that biofuels would be a good way to reduce global warming by cutting greenhouse gas (GHG) emissions.
In reality, biofuels could actually increase GHG emissions if we consider their effects over their entire life cycle. In a study by the University of Edinburgh, their impact has even been quantified: biofuels could increase GHGs by 50 to 70%. So before going any further with biofuels, we must carefully evaluate all of their environmental effects.
Not only it’s causing more GHGs but it’s also causing food shortages in many parts of the world. Global food stocks are officially at their lowest in nearly 25 years.
There have already been riots in over 30 countries, including Haiti. And this food crisis could worsen in the short term.
