Fuel for aircraft and vehicles has a huge effect on the climate. If fossil fuels can be replaced by crop-based fuels, would you be willing to use certain food crops to produce bio-energy?

Bio-fuels risk creating famine
Today, ethanol fuel is produced around the world from maize, rape, grain or other feed crops for animals that take the place of crops for human food consumption in fields and put upwards pressure on the price of foodstuffs. It’s a crime against humanity to use fertile farmland for growing crops that are to be used as fuel.
There should be a 5-year moratorium on turning food crops into fuel until technological progress has made it possible to use plant remains from food production instead, i.e. so-called second generation technologies.

Plants as solar collectors
The effect on food prices isn’t as severe as is claimed, but of course you have to be careful. I believe it’s possible to produce ethanol fuel by means of first generation and check food prices at the same time.
There’s no doubt that second generation technology is preferable because then we can combine food production with biomass production, as we don’t want foodstuffs to compete with agricultural products. Plants are solar collectors, and if we use them correctly, there’ll also be a great environmental benefit for the transport sector.
