Biofuel Displacing Food Crops May Have Bigger Carbon Impact Than Thought

Biofuel Displacing Food Crops May Have Bigger Carbon Impact Than Thought

Besides food crops displacement, it raises a very good point about N2O emission from the production of nitrogen-based fertilizers. N2O is a very potent ozone layer destroyer, and it also contributes to acid rain---an equally serious environmental problem as global warming. It doesn't make a lot of sense to me to replace fossil fuel by biofuel, if it's equally unsustainable environmentally . Why don't we put our priority on cutting down fuel consumption first, then to consider other renewable energy sources?

Remember the slogan: reduce>reuse>recycle

Reduce should come first.

Despite all the marvellous progresses that the Cuban people have made since the triumph of the revolution, struggles still continue.
