All of the following are advantages of organic farming as compared to conventional farming EXCEPT: fewer pollutants are released into the environment.

NOT:

The advantges of organic farming compared to conventional methods of farming which are actually the most widespread types of farming are that they will release fewer pollutatns into the environment. They will also increase the biological diversity of crops and reduce the use of argicultural chmeicals. 

However, what is NOT a advantage of organic farming compared to conventional farming would be higher crop yields as conventional farming will have higher yields every season mostly due to the use of conventional agricultural chemicals.
