Studies that look at the impacts of growing biofuels must be multi-dimensional: Too often, studies analysing the impacts of growing biofuels focus only on one element of food security, such as access to land, without looking at the impact on other aspects of food availability and access to food.
Karas said the FDA is planning on releasing a review of potential environmental impacts of growing the salmon – and soliciting public comments on that review – before reaching a decision.
At age 48 months, the trial indicated mixed performance with both positive and negative impacts of growing some species in mixtures compared to monocultures.

The revisionist effort to increase the percentage of ethanol blended with U.S. gasoline continues to ignore the major environmental impacts of growing corn for fuel and how it inevitably leads to higher prices for this staple food crop.
It could also help assess the potential negative impacts of growing crops for biofuels, since some feedstocks may require fertilizer that will generate N2O that offsets their carbon neutrality.
