But some scientists and green groups say biofuels contribute more greenhouse gases than they save. Then there is the affect on food production when land is taken over for growing plants to produce biofuels. The cost of some foods is already going up because of this.
So is it right to take land out of food production so as to produce biofuels for us in the developed world to be able to drive our cars while people in other less privileged circumstances have to go hungry because of rising food prices?
Seems to depend on who's saying what.Transport is not the biggest producer of CO2,bio-fuel produces less harmful emissions,and car manufacturers are already striving to produce ever decreasing emissions from their vehicles...or so the article I read recently says.
