What are biofuels?
From an etymological perspective, would be the fuels of biological origin, but this definition would include oil, since this comes from fossils that have existed for millions ofyears. A better definition would be that they are bio-based fuel derived renewably from organic waste. Biofuels are the primary source of energy in human history. Among the sources of biofuels arebiomass from crops such as sugarcane, maize, sorghum, cassava and others, used to produce ethanol, and oils from palm, soybean, castor, Jatropha curcas, canola and other plants used to produce biodiesel.Will increased production biofuels will jeopardize the food security and increase the prices of certain foods?
This would be true if land for planting food crops used for biofuel production, or ifyou replace the original purpose of these crops and are used for biofuel production.

It should be noted that over 50% of the poor in Latin America and the Caribbean lives and depends on the ruralsector. Of the 525 million people in Latin America, 128 million live in poverty (less than $ 2 per day) and 50 million in extreme poverty (less than $ 1 per day). Consequently, if there are crops thatgenerate more income to producers, they will focus their efforts on those crops. You need better pay farmers for their products, but it is extremely important to have clear policies about it, toprevent the destruction of wildlife reserves and allocate land to the cultivation of these crops. It also must establish regulations aimed at maintaining a balance between the amount of produceconsumption-oriented food and bioenergy production, in order to avoid jeopardizing food security.

The problem is that the price of certain foods has increased, as is the case of corn, due to increased demandfor use in ethanol production. As mentioned by the magazine Foreign Affairs (2007), it is often exaggerated the impact of higher prices due to the production of ethanol, which also contributed...
