Because of the low photosynthetic efficiency and the competition of energy plants with food plants for agricultural land, we should not grow plants for biofuel production. The growth of such energy plants will undoubtedly lead to an increase in food prices, which will predominantly hit poorer people.
Competition gives birth to a lot of success, and if no one ever challenged you, you wouldn't go anywhere. It makes sense to compete with others for a promotion at work. But so many women take it a step further and won't even support other women. They end up competing over things that don't make sense - like how we look.
