If we use crops for biofuels, won it mean that we don have enough food for everyone?
No. If more crops are required to satisfy demand for both food and biofuels, the market will respond accordingly. The Food and Agriculture Organisation of the UN estimates that no more than 1% of the available land for agriculture in the whole world was used for biofuels in 2004. They also estimate that this will only rise to 2% by 2030. Not all suitable agricultural land is in use at present and farmers will respond to increased demand by increasing crop yields and planting on more land. In addition, the main co-products in the production of biofuels provide high-protein animal feed for the livestock sector.
