If biofuels help us to pollute less the planet, we need a lot of water and cereals to produce them.
What should we do?
If we keep using oil, there will be more and more greenhouse gas into the atmosphere, glaciers will melt, there will be big storms, temperatures will rise . . .
And there will be oil shortage.
So we have to use biofuels.
But, if everyone can't eat enough, and if there are bad harvests today, (how) what will we do when biofuels will be widely commercialized ?
It needs a lot of cereals, and about 4000 liters of water to produce one liter of bio-ethanol.
So, biofuels contribute to the food rising costs, and this increase penalizes the population.
In addition, they contribute to the deforestation : when they gain some lands and make them suitable for cultivation, they aggravate (the) pollution.
Today, we can't be sure that biofuels are the best solutions to preserve the Earth. We still have to work on biotechnologies.
