proofread this paragraph?
you might have seen this before because ive been posting alot of my essay .. but ive been making alot of changes .. please proofread!! 
In addition to being responsible for deforestation and food shortages, biofuels will also be responsible for the dramatic increase in retail grocery prices. As biofuels become more attractive as an alternative fuel to government officials and the general public, who are unaware of the consequences, food prices will rapidly proliferate as our food supply is used up to make these fuels. Farmers will digress from growing crops for food in order to grow crops for biofuels because they will be getting paid more per acre. As farmers are rewarded to sever our food supply, consumers will suffer due to the shortened supply. Worldwide, people will not be able to afford to provide for themselves and their family, which will ultimately cause many people to become distraught and deranged.
Update:As President George W. Bush is demanding that biofuels become more widely available in order to help consumers save money at the pump, food prices are already steadily increasing. For instance, many dairy products, such as milk and cheese, have already risen by ten percent. Consumers will be paying almost $4.00 for a gallon of milk (Pyle). It is obvious that if biofuels continue to be supported by government officials, consumers might spend less at the pump, but spend more at the grocery store.

2nd paragraph looks fine, you might want to add the word 'Even' as the first word of the paragraph and replace 'is demanding' with 'demands'
1st paragraph has some words used incorrectly.
Find a synonym for 'be(ing) responsible', as you use it twice in the first sentence (only use it once, otherwise it sounds repetitive). I suggest using the word 'cause' or 'causing').
proliferate is not the correct word, I suggest using 'increase', or 'rise'.
digress is not the correct word, suggest using 'diverge' or rework the sentence to read something like "Farmers will replace crops grown for food in order to grow crops for biofuels..."
Replace: As farmers are rewarded to sever our...
With: As farmers are rewarded for severing our...
Also, shortened might not be the best word here (although it works). The word 'tightened' may work better.
distraught and derranged are not appropriate words here, suggest replacing "cause many people..." with "cause great suffering and increased starvation."
I'm going to assume you only want grammar notes, rather than content notes...it's hard to edit without changing font or color, so I used asterisks. Hope it's understandable:
In addition to being responsible for deforestation and food shortages, biofuels will also be responsible for the dramatic increase in retail grocery prices. As biofuels become more attractive as an alternative fuel *to government officials and the general public, who are unaware of the consequences* (unnecessary), food prices will rapidly proliferate* (reconsider word choice) *as our food supply is used up to make these fuels* (unnecessary) as farmers will digress* (reconsider word choice) from growing crops for food in order to grow crops for biofuels because they will be getting paid more per acre. As farmers are rewarded to sever* (again, word choice) our food supply, consumers will suffer due to the shortened supply. Worldwide, people will not be able to afford to provide for themselves and their family*(ies), which will ultimately cause many people to become distraught and deranged* (word choice again).

As President George W. Bush *is demanding* (demands) that biofuels become more widely available in order to help consumers save money at the pump, food prices are already steadily increasing. For instance many dairy products, such as milk and cheese, have already risen by ten percent. Consumers will be paying almost $4.00 for a gallon of milk (Pyle). It is obvious that if biofuels continue to be supported by government officials, consumers might spend less at the pump, but spend more at the grocery store.
