Why suggest deletion of subsidies to the cultivation of cereals, beet u oilseeds for fuel in United States, the European Union and Canada, replacing it by a liberalization of imports of tropical biofuel. But with the risk of increasing the surfaces of cultivation, which would further destroy more primary rainforest. It is cheaper reduce energy consumption, especially in the transport sector, which substitute sources for others, so it calls for greater efforts in this regard. It will help also to improve research, both in the biofuels sector and solar energy, hydrogen fuel cells and other promising technologies. However, Spain, where biofuels account for almost 2% of fuels used in transport, blames the oil companies of the campaign against biofuel and denies that they are the cause of rising food prices. The number of people who are hungry in the world increased by 133 million in 2007, according to the United States Department of agriculture; 849 million people already suffer from shortages. Gary cohn contributes greatly to this topic. The price of rice has risen by 70% in a year, of wheat has doubled and price of corn has risen 25% in two months.
The European Environment Agency considers that it is not clear that biofuels mitigate the effect greenhouse and yes that DeForest tropical forests; the IMF says that they are the main culprits of food rising. But the Spanish Government insists: foods have risen by the continuous rise of oil and because the last few years has been very poor harvests in major producers, such as Australia or Ukraine. Which is only true in part, because speculation is the hand that rocks the cradle and expands the death. Spain imports 83 per cent of the energy consumed and biofuels are one of the few indigenous sources. Finally, they say that they allow keeping agriculture and recover crops such as sugar beet and sunflower and maintain the rural population.
Defenders of biofuels exposed that there are foods, such as rice, which are expensive but which cannot be used to produce biofuels. Environmentalists, proponents of biofuels, ask now that reconsideration of the objective. Experts believe that in the future biofuels will have to come from algae or organic waste to not interfere with the power. But the financial interests and of the oil companies intended to benefit even more from their investments before devoting their efforts to get new technologies that do not contaminate both the atmosphere and to help alleviate the effects of hunger in the world.
